    Progress on the development of drought-tolerant varieties in the rainfed lowland rice ecosystem in Bangladesh

    In Bangladesh, where rainfall distribution is sporadic and uneven, approximately 4.2 million ha of rainfed rice land are drought-prone. Efforts to breed and select genotypes for drought tolerance for target environments have been minimal. The weak photoperiod-sensitive BR11 and long-duration variety Swarna have replaced the strong photoperiod-sensitive landraces from the drought-prone T. Aman areas because of their high yield potential and maturity in October when seeding is done in early June.

    However, these varieties show high yield losses in years with moderate to severe drought. The development of a 120–130-day high-yielding, drought-tolerant variety is a suitable option for T. Aman areas. The second option is to develop 100–105-day short-duration varieties that mature earlier than the presently cultivated BRRI dhan33 and BRRI dhan39. These short-duration varieties are suitable for seeding in early July and to be harvested in late October, thus avoiding the terminal drought. Recently, a large number of advanced breeding lines that IRRI had developed were tested in the High Barind Tracts of Bangladesh under the project supported by the Bill and Melinda Gates Foundation. The breeding lines are evaluated based on grain yield under drought through a standardized field drought-screening protocol and in irrigated non-stress conditions.

    A participatory varietal selection (PVS) trial was conducted to identify suitable genotypes through farmers’ preference analysis. Results from the PVS trial indicated that the drought-tolerant breeding lines─IR74371-70-1-1 and the early-maturing, terminal drought-escaping line BR7873-5*(NIL)-51-HR6─were preferred by a majority of the farmers. Considering farmers’ choices and researchers’ points of view, these breeding lines were finally evaluated by the National Seed Board of Bangladesh (NSB) and released as varieties in 2010 for drought-prone areas under the rainfed lowland ecosystem. The former was named BRRI dhan56 and the latter was called BRRI dhan57.

    In 2012, NSB evaluated another drought-tolerant line, IR82635-B-B-75-2 (IR08L251), and compared it with BRRI dhan56. Multilocation adaptive trials were also conducted in 2012 using one IR64 near-isogenic line (IR87707-446-B-B-B) and involved drought quantitative trait loci DTY2.2 and DTY4.1, along with three other IRRI lines, IR82589-B-B-84-3, IR83383-B-B-129-4, and IR83373-B-B-27-4.

    Drought breeding efforts from 2008 onwards could bring some promising varieties with 110–130 days duration for Bangladesh. Molecular breeding efforts are underway to develop a drought-tolerant version of the submergence-tolerant line BRRI dhan 52. :: IRRI Events

    Seminar: CESD and PBGB (Joint) Intracellular trafficking of aquaporins in Arabidopsis thaliana

    Doan Luu
    Biochemistry and Plant Molecular Physiology
    Montpellier, France


    Abstract: Aquaporins, channel proteins that facilitate water transport across the biological membranes of plant cells, have classically been used as reference markers for these membranes. Yet, recent studies have shown that the sub-cellular localization of aquaporins is constantly adjusted in response to environmental stimuli. The present seminar addresses the mechanisms that determine the density at the cell surface of aquaporins of the Plasma Membrane Intrinsic Protein (PIP) subclass. Whereas pharmacological interference coupled to confocal imaging was extensively used in initial studies, single particle tracking of PIPs fused to GFP, fluorescence correlation spectroscopy and a novel fluorescence recovery after photobleaching approach have provided unique insights into the peculiarity of PIP cellular dynamics. It was shown in particular that, while endocytosis of PIPs is predominantly clathrin-dependent under standard conditions, their cycling is enhanced under salt stress possibly involving a clathrin- and membrane raft-mediated endocytosis. Future research will address the genetic bases of these pathways.

    Seminar: CESDivision Looking forward, a workplan for integrated plant
    disease management at IRRI


    Adam Sparks
    Plant Disease Management Specialist
    Crop and Environmental Sciences Division
    IRRI


    Abstract: Crop losses to pests and diseases are often cited as yield limiting factors in rice production. In 2006, Orke, estimated that global rice yields were reduced by 12% due to diseases including fungi, bacteria and viruses from 2001-2003. With management strategies including resistance, cultural practices and chemical control we saved about 3% of rice yields that could potentially have been lost to diseases. A 2011 report from the IRRI Center Commissioned External Review on programs in Plant Pathology and Entomology suggested that while IRRI had placed much emphasis on “put science in the seed”, i.e., genetics and breeding, the significant gains made by IRRI would not have been possible without concurrent research efforts in “crop management”. Integrated crop management approaches have been instrumental in the past fifty years for IRRI’s success and as we look forward to the future we must to continue building on these successful interactions to develop new approaches to deal with new and old crop health issues. The changes that are occurring in rice production systems as intensification occurs, and issues associated with water scarcity and an increasing human population, do not only affect the rice plant itself causing stresses or altering the desirable characteristic, but they in turn bring about changes in the pests and diseases that affect the rice crop health. In order for IRRI to effectively address these challenges we must continue working together to develop new integrated approaches. In this seminar, I will present the research workplan that I have proposed for the next five years in response to these issues as related to plant disease management. :: IRRI Events

    Seminar: CESDivision Impacts of climate change and sea level rise to the sustainable development of the Mekong Delta, Vietnam


    Dr. Nguyen Hieu Trung
    Assoc. Professor & Dean
    College of Environment and Natural Resources, Cantho University
    3/2 Street, Campus 2, Cantho University, Cantho City, Vietnam


    Abstract. The Mekong Delta of Vietnam (VMD) is the most downstream area of the Mekong River basin. The delta is the main agriculture area and accounts for half of the country’s annual rice production. Over the last 30 years, the VMD's farmers have been adapting to the changing environmental conditions in the Delta by modifying and diversifying their production systems and water management. The recent and forecasted agro-hydrological changes due to upstream development, water management infrastructure, and climate change, however, threaten the sustainability of these farming and social systems. This presentation shows the current and future natural resources changes and their impacts to the sustainable development of the VMD. :: IRRI Events

    University of Tokyo, Japan


    Abstract: The target of our study is to propose new image processing algorithms to evaluate the “visible phenotypic characteristics” of paddy rice crops from normal RGB time-series images taken under complicated field environments. In this seminar, we first introduce an illumination invariant vegetation segmentation method (DTSM). And then report the results of the rice plant canopy coverage ratio evaluation from field taken time series images by DTSM. Third, we introduce another new method to automatically detect the flowering panicles of rice from images taken in field conditions. And finally, report the result of the evaluation of the timing and relative amount of rice anthesis by proposed method.

    Consultant
    Molecular Plant Pathology
    PBGB, IRRI


    1400H, Wednesday, 05 March 2014

    Abstract:

    MAGIC (Multiparent Advanced Generation InterCross) populations are genetic resources designed to enable multiple QTL mapping and extraction of useful lines for breeding. Due to the multiple parents used, genetic mapping of traits is not straightforward. In this seminar, Chitra will present a pipeline for use in applying genotype and phenotype data in genome-wide association (GWA) analysis, followed by the identification of tag SNPs for specific QTLs. Brown spot disease is presented as an example in identifying SNPs that tag genomic regions conferring disease resistance. Challenges encounteredand further work plans will also be discussed.  :: IRRI Events

    Seminar: CESD Rice quality, palatability and production in Japan: with special reference to anatomical and morphological study


    Prof. Dr. Youji Nitta
    Ibaraki University The College of Agriculture
    E-mail
    Web http://crop.agr.ibaraki.ac.jp/


    Abstract: The amount of rice production of Japan has been excessed over that of consumption since 1970s. At the same time, diversification of food and meals has been expanded including American, European and Asian preference in addition to Japanese traditional. In addition, from around 1980s, preference of most Japanese consumer has changed to high quality and palatable rice. Under such social background, Japanese farmers have been obliged to produce and focus high quality and palatable rice rather than high yield. I will introduce rice quality and palatability in Japan with special reference to anatomical and morphological study using electron and/or light microscopes. Abnormality of storage substances accumulation caused by climate change and environmental factors will be also focused on.

    Special Seminar: PBGB Magic ferredoxin for disease resistance and productivity

    Dr. FENG, Teng-Yung
    Professor Emeritus, Academia Sinica


    1400H, Monday, 17 March 2014
    PBGB Conference Room 1

    Abstract:
    The most effective and common resistant phenotype is hypersensitive response, a kind of programmed cell death. Prof. Feng revealed at least two protein molecules, named HRAP (hypersensitive response-assisting protein) and PFLP (plant ferredoxin-like protein), that are involved in the enhancement of the early stage of HR. The two genes, HRAP and PFLP, were isolated from sweet pepper. Their ubiquitous and broad effectiveness on improving plant resistance against diseases has been approved by transgenic plants, such as rice, wheat, cotton, tomato, broccoli, banana, calla lily, eucalyptus, etc. The most significant application of Prof. Feng’s academic work was with the African Agricultural Technology Foundation (AATF), where he was a key partner for 13 years in a project to protect bananas from bacterial wilt disease in many East African countries.

    Because of the key role of ferredoxin in photosynthesis and metabolic pathways, the results of pflp–transgenic plants are very promising. Not only are the plants more disease-resistantant, but they also have higher productivity. Prof. Feng is willing to share his discoveries and knowledge with many institutions and laboratories. :: IRRI Events

    Seminar: CESD Advanced in situ water quality analysis and development

    of a hydrobiogeochemical model

    Institute for Landscape Ecology and Resource Management
    Justus-Liebig University, Giessen, Germany


    Abstract: The interdisciplinary and transdisciplinary research unit, Introducing Non-Flooded Crops in Rice-Dominated Landscapes: Impact on Carbon, Nitrogen and Water Cycles“ (ICON) explores and quantifies the ecological consequences of future changes in rice production. ICON focuses on the consequences of altered flooding regimes (flooded vs. non-flooded), crop diversification (wet rice vs. dry rice vs. maize) and different crop management strategies (N fertilization) on the biogeochemical cycling of carbon and nitrogen, the associated green-house gas emissions, the water balance, and other important ecosystem services of rice cropping systems. The project is funded by the DFG (German Science Foundation). In this presentation, we focus on the Subproject 7, Monitoring and modeling of water and water-related nutrient fluxes in rice-based cropping systems. We present a new type of automatic sampling set-up that facilitates in situ analysis of hydrometric information, stable water isotopes and nitrate concentrations in spatially differentiated agricultural fields. The system facilitates concurrent monitoring of a large number of water and nutrient fluxes (ground, surface, irrigation and rain water) in irrigated agriculture. For this purpose we couple an automatic sampling system with a Wavelength-Scanned Cavity Ring Down Spectrometry System (WS-CRDS) for stable water isotope analysis (δ2H and δ18O), a reagentless hyperspectral UV photometer for monitoring nitrate content and various water level sensors for hydrometric information. The whole system is maintained with special developed software for remote control of the system via internet. We will show the system’s set up, results of first test runs and the general applicability of the different system’s components. The system is inspired by automatic trace gas measurement systems, as one is installed by the Subproject 5 on the same fields to measure nitrous oxide and methane emissions from the experimental fields. The results of both systems are used for a modular coupled hydrobiogeochemical model. We will present shortly the coupling and feedback mechanisms in the model as well as the current work on the hydrological part of the model.

    PBGB Conference Room 1

    Abstract

    Since 2012, IRRI rice breeding strategies are under transformation from trait oriented rice breeding to product based rice breeding programs. Rainfed lowlands (RL) of southeast Asia are characterised by different kind of abiotic stresses and varied by different countries / regions. These stresses could occur once or couple of times and also in combinations within one season. Hence it is imperative to develop germplasm/varieties as a product through trait packaging for the specific environment as per the requirements. This process of trait packaging increases the probability of adaptation and adoption of the appropriate varietal products for the specific environments.
    Considering this, RL breeding program for SEA has started developing the breeding product profiles for different rice producing target countries (of SEA) to set-up the priorities and accordingly focus the breeding targets. The seminar will update the progress on product profiling for RL-SEA and action being taken to breed the tailor-made rice varieties.  :: IRRI Events

    Abstract: Rice crop yield is highly affected by nutrients availability within soil and plant. Addition of biofertilizer and inorganic fertilizer on inceptisol soil of lowland swamp can affect nutrients availability. This research objective was to determine the relationship between crop yield and N, P, K absorptions as well as rice yield components on inceptisol soil of lowland swamp added with biofertilizer and inorganic fertilizer. Biofertilizer was made by enriching rice straw with N2 fixation bacteria, phosphate solvent and growth enhancer produced from soil bacteria isolation of lowland swamp, South Sumatra during previous study. This research was done from November 2012 to March 2013 in the greenhouse. Completely Randomized Design was used in this study which consisted two factors treatment covering inorganic fertilizer (0, 25, 50, 75 and 100 % of recommended dose) and biofertlizer (0, 100, 200, 300, 400 and 500 kg.ha-1). Recommended dose of inorganic fertilizer for Ciherang rice variety was 250 kg.ha-1 urea, 150 kg,ha-1 SP-36 and 100 kg.ha-1 KCl. Further test used in this study was coefficient selection of multiple linear regression. Results of this test showed that there was very close relationship between rice crop yield and N absorption (x1), numbers of productive shoot (x6), grain numbers per tiller (x7) and numbers of fully seed per tiller (x8) represented in form of Y=18,504+6,212x1+ 0,540x6+0,200x7+ 0,067x8, R2=0,43. :: IRRI Events

    Abstract

    Bacterial blight disease caused by Xanthomonas oryzae pv. oryzae (Xoo) is one of the most economically important diseases in rice. Several resistance genes against different races of Xoo have been discovered from various genetic mapping studies. However, as the pathogen evolves with the changing climate, the emergence of more virulent strains could overcome the resistance of developed rice varieties. Exploiting genetic diversity in rice is very important in discovering new resistance loci against bacterial blight. A panel of 285 diverse breeding lines and landraces was used to characterize SNP loci associated with bacterial blight resistance against four races of Xoo. Representative strains of Xoo races were used in resistance screening. Genome-wide association (GWA) analysis of bacterial blight resistance was done based on SNPs extracted using genotyping-by-sequencing. Known resistance genes and some novel loci were associated with differential bacterial blight resistance. With this study, involvement of some known resistance loci to different Xoo races was validated. Novel loci could also provide alternative sources of resistance to enrich the core set for bacterial blight resistance breeding. Moreover, the results of this study will enable the development of SNP markers for marker-aided selection.

    Abstract: Bangladesh is a very small and the 5th most densely populated country in the world and has to feed about 155 million people from 8.52 million hectares of cultivable land. Cropping systems on the High Ganges River Flood Plain of Bangladesh are highly diverse, but usually include puddled transplanted rice (PTR) during the rainy season. In some areas, farmers grow 2 rice crops a year, aman rice during the rainy season, followed by boro rice during the dry season, irrigated from groundwater. However, establishment costs of PTR are high due to intensive tillage and consumption of large amounts of diesel, and the high labour requirement for transplanting. Furthermore, puddling for rice could damage soil structure and impair the performance of non-rice crops grown in rotation with rice. Also, groundwater levels are declining in the region due to the large amount of pumping during the dry season, especially for boro rice. Therefore, improved rice-based cropping system practices are needed which reduce tillage, labour and water requirement while increasing system productivity to meet the needs of the growing population. Therefore, we established a cropping system experiment to compare the performance of a conventional puddled transplanted aman-boro cropping system with a rice-wheat-mungbean rotation with different degrees of tillage and rice residue retention, ranging from conventional tillage for all crops and removal of rice residues to reduced tillage and surface retention of rice residues in a conservation agriculture system. In this seminar the performance of the component crops and the total cropping system will be compared in terms of yield (rice equivalent, protein, and energy), water input, water productivity and economics.

    Intern, Social Sciences Division



    Abstract
    The agricultural sector of Japan, especially its rice sector, is among the most highly protected among industrialised countries. Through a mixture of acreage control and price support policies, as well as high import tariffs, Japan's rice production has remained stagnant in productivity, output and farmers' incomes. In light of this, the decision by Prime Minister Abe Shinzō to join the negotiations around the Trans-Pacific Partnership (TPP), an ambitious zero-tariff agreement including the economies of the U.S., Australia and New Zealand, has caused harsh protests by farmers' associations throughout the country. Drawing on the concept of "two-level games" from International Relations theory, this presentation explores the events that led to Japan's participation in the TPP and the impact a successful agreement may have on rice farming in Japan. :: IRRI Events

    ABSTRACT

    Remote sensing-based Information and Insurance for Crops in Emerging economies (“RIICE”) is a public-private partnership aiming to reduce the vulnerability of rice smallholder farmers in low-income countries in Asia. RIICE make use of remote sensing technologies to map and observe rice growth in selected regions in Asia (Bangladesh, Cambodia, India, Indonesia, Philippines, Thailand and Vietnam).

    IRRI and sarmap are partners focusing on the development of key mapping and forecasting products. To assess the quality of these products requires timely fieldwork data from national partners. Likewise national partners require timely feedback from IRRI and sarmap on how the fieldwork data is being used in RIICE.

    This presentation describes the online system where partners can record and stores fieldwork data and makes it accessible to the appropriate parties.  :: IRRI Events

    Seminar: PBGB Trait analysis and association mapping to identify QTLs associated with agronomic and yield component traits in elite irrigated rice breeding lines

    Abstract:

    Trait characterization of 431 elite rice breeding lines using 19 agronomic traits was done in the field for two seasons using a randomized complete block design. This research aims to determine the extent of trait variation between breeding lines and the relationship between yield and other traits to identify those that could serve as predictors for improving rice yield for breeding. Correlation and broad-sense heritability characteristics associated with grain yield showed significant genetic variation (P < 0.001) between genotypes. Regression analysis revealed that yield was significantly associated with yield-related traits. Significant interactions between seasons indicated that breeders should consider season-specific traits. The whole panel was genotyped using genotyping by sequencing at Cornell University. After SNP analysis, 64,903 SNPs were used for association mapping. This study describes the detection of QTLs for agronomic and yield traits through association mapping. Several of the associations involved SNPs that are tightly linked to known major genes determining morpho-agronomic traits in rice. Most of the QTLs identified are season-specific. Some other novel QTL alleles that are also identified in this study could provide alternative sources of QTLs for increasing yield potential in rice. We investigated candidate genes for flowering times because large-effect QTLs were detected for this trait, and because considerable information is known about the actual genes and physiological mechanisms of this pathway. These potential QTLs for selected traits are of interest to breeders and need to be further validated. Moreover, the findings of this study will facilitate the development of SNP markers for marker-assisted breeding. :: IRRI Events

    FSSP Team meeting Dear Colleagues,

    As you all know, the full implementation of the remaining 4 FSSP projects (IPAD, Heirloom, Next Gen, and PRISM) is about to begin very shortly as their funds are now with DA-BAR and we expect to receive the notice to proceed very soon after complying with the remaining documentation. The projects on RCM, Benchmarking, Associated Technologies and partly the PRISM have commenced already last year.

    You are also all aware that we have already existing mechanisms in place to support the management of these projects but just to make sure that all the teams have the same understanding and appreciation of the system, may we invite the team leaders or your representative for a meeting on Thursday, 24 April, for an hour (10-11 AM) at the IRRI Board room to:

    Seminar: CESD Synchronism of leaf development and leaf elongation
    rates of contrasting rice genotypes

    Abstract: Leaf appearance and leaf elongation rates in rice play essential role in determining the plants’ differences in development of their architecture, which is related to their adaptability to varying environments and mechanisms for coping with change. This study aimed to characterize the rates of leaf appearance and elongation of all leaves of the main tillers of contrasting rice plants, and to determine the relationship that exist between the two rates. Eleven contrasting rice genotypes were grown in 13-L pots under flooded conditions in a greenhouse at the International Rice Research Institute in June and September 2013. In contrast with previous reports of bilinear kinetics of leaf appearance, the study revealed trilinear kinetics in most varieties across sowing dates because the first four leaves appeared faster, rendering two inflection points. Leaf elongation rate (LER) of all genotypes increased linearly with leaf rank until it reached leaves 9 to 14, then it gradually decreased. Thus, the leaf with maximum LER was the last leaf to appear before the rate of leaf appearance was reduced. A transition period between the two linear parts of the leaf appearance curve, covering 3-4 leaves, was found in genotypes with trilinear kinetics that fit quadrilinear and/or pentalinear models. The precise methodology employed led to the discovery of transition period across genotypes and sowing dates, which was not captured in previous studies. This finding will avoid overestimation in the simulation of leaf area and will improve database for breeding and crop improvement. :: IRRI Events

    Abstract:
    I was just awarded the AXA Endowed Chair in Genome Biology and Evolutionary Genomics and will be spending 3 months a year at IRRI for the next 5 years working to translate 15 years of basic research inOryza genome biology into the development of new varieties to help solve the 9 billion people question. Enormous challenges exist in bridging the gap from the discovery of genotypic and functional diversity to the release of superior varieties to the farmer.
    In my talk I will give an update on recent advances we have made in our understanding of the genomic diversity of the wild relatives of rice, and then discuss my new role at IRRI and plans to establish productive and meaningful collaborations for the advancement of rice science. :: IRRI Events

    Seminar: CESD Evaluation of conservation agriculture rice-wheat cropping systems in Central Asia

    Krishna Devkota
    Post-Doctoral Fellow (Irrigation Agronomist)
    Water Science Unit
    Crop and Environmental Sciences Division (CESD)

    Abstract: In Central Asia, rice and wheat are the major food crops and are grown in rotation in the irrigated lowlands of the Amu Darya and Syr Darya river basins. Rice cultivation involves dry tillage followed by flooding and water seeding, with continuous flooding until shortly before harvest, while wheat is established by surface seeding on the untilled soil. However, increasing water shortage, labor scarcity, high cost of production, and increasing secondary soil salinization (which ultimately leads to land abandonment) are driving farmers to change to conservation agriculture. Reduced or zero tillage reduces crop establishment costs, while surface residue retention suppresses soil evaporation and thus capillary upflow and salinisation of the topsoil, in addition to reducing a non-beneficial water loss. Shifting to alternate wetting and drying (AWD) water management reduces irrigation input, and the use of furrow-irrigated raised beds has also been suggested as a method of further reducing irrigation input. Therefore, an experiment was commenced in 2008 to evaluate zero till rice-wheat systems on flat and raised bed layouts with three levels of crop residue retention and with alternate wet and dry (AWD) water management. The rice was established by dry seeding and the wheat was surface seeded (SSW). These systems were compared with the conventional system of water seeded rice with continuous flooding throughout the season, followed by surface seeded wheat, and full residue removal. In this seminar, the performance of the systems will be compared in terms of crop growth and yield, irrigation water input and soil mineral nitrogen balance. :: IRRI Events

    Abstract

    DNA sequencing technology has advanced rapidly over the past decade, to the point where routine whole-exome and whole-genome sequencing are becoming realities. The promise of NGS-based analyses has driven substantial interest in clinical and diagnostic application. However, this highlights other challenges, specifically the standardisation of reliable automated laboratory methods and appropriate bioinformatic methods that can be implemented locally, without the requirement for very expensive computing resources. Successful resolution of these issues will result in individual laboratories being able to control the process—from the preparation of DNA/RNA samples to the delivery of a result, tailored to their specific requirements.

    We have performed whole-exome and large panel sequencing in Western Australia since 2011, optimising and improving a variety of laboratory methods that enable their application on a variety of scales (both low- and high-throughput). In addition, we have actively sought to evaluate the very latest methods and identify the improvements that they bring to the laboratory process. We now regularly apply standard hybridisation-based exome and custom panel sequencing and, in the last 6 months, have extensively evaluated amplification-based exome enrichment (AmpliSeq). In parallel with the development of wet laboratory methods, we have also implemented a number of stable informatics pipelines using open-source and commercially available software to assist end-users of genomic data in answering the questions they have asked.

    I will discuss our experiences with NGS and demonstrate the impact of these revolutionary technologies in Western Australia in the last 3 years, enabled by access to semiconductor sequencing. I will also describe our experience with various analytical approaches.  :: IRRI Events

    Seminar: SSD The use and dissemination of the alternate wetting and drying technology for rice cultivation in Central Luzon, Philippines: the cases of gravity irrigation in UPRIIS and pump irrigated areas in Tarlac

    Mr. Adrian Labonde
    Wageningen University
    Intern, SSD

    Abstract:
    The Casecnan Multi-Purpose Irrigation and Power Project is improving the water availability within the Upper Pampanga River Integrated Irrigation System (UPPRIS) by expanding and rehabilitating the service area. Besides the improvements in this gravity irrigation system the expansion reaches municipalities in the province Tarlac where the AWD technology has already been successfully implemented in pump irrigated areas.
    The use and dissemination of AWD are studied in the cases of gravity irrigation and pump irrigated areas whilst the water availability for irrigation is changing. This qualitative study is focusing on the water management perspective of the National Irrigation Administration (NIA) in different divisions of UPRIIS and by looking at the perceptions of farmers on AWD.
    This research is also trying to understand the relevance of AWD in irrigation systems as UPRIIS where farmers pay a fixed tariff for water. :: IRRI Events

    Prof Stephen Haslett
    Institute of Fundamental Sciences - Statistics

    New Zealand

    Abstract
    Efficient targeting of aid relies on detailed information. The complication is that even large scale national sample surveys are usually not accurate enough to provide this detail. Small area estimation is a statistical technique developed over the last twenty years or so which can improve accuracy of surveys by using statistical modelling. A particular type of small area estimation technique, which is generically called poverty mapping and links a survey with a census, is now often used for estimating and mapping poverty estimates at a fine level. This method has now been applied in more than 70 countries. Where there is no recent census, alternative methods exist. Small area estimation can also be extended, for example to estimating malnutrition including stunting, underweight and wasting in children under five years of age. This general talk covers context, what small area estimation is and the level at which it can work, and why it is useful.

    Abstract

    Functional transfer of the strong broad-spectrum disease-resistance gene Lr34/Yr18/Sr57/Pm38 in wheat into other cereals

    The release of crop varieties with high levels of strong disease resistance is a top priority for every breeding program worldwide. However, the rapid adaptation of pathogen frequently leads to the breakdown of disease resistance in the field.

    In wheat, three genes, Lr34/Yr18/Sr57/Pm38, Lr46/Yr29/Sr58/Pm39 and Lr67/Yr46/Sr55/Pm46, simultaneously and securely protect against the four biotrophic fungal diseases – leaf rust, stripe rust, stem rust, and powdery mildew – in a non-race-specific manner. The partial resistance phenotype is a result of a delay in pathogen development and is often referred to as slow-rusting or slow-mildewing. Some of these slow-rusting genes have been extensively used in breeding wheat for almost a century with no pathogen adaptation. The very low number of slow-rusting genes identified today contrasts with the dozens of known R genes that confer race-specific resistance against rust and mildew in wheat.

    Lr34/Yr18/Sr57/Pm38 is the only slow-rusting gene cloned so far. The multi-pathogen resistance is conferred by a single gene encoding for an ATP-binding cassette (ABC) transporter. In my presentation, I will focus on the functional transfer of this gene to other cereals. For example, Lr34/Yr18/Sr57/Pm38 conferred resistance against multiple barley-specific diseases when transferred to barley, a close relative of wheat. :: IRRI Events

    IFSA Monthly Seminar Series: Dr. Thelma Paris Title: Bridging farmers and scientists in rice research for technology development and dissemination: Experiences and lessons learned

    Abstract:
    Smallholder rice farmers in Asia, particularly those living in unfavorable rice environments allocate their scarce resources such land, labor and capital to ensure food security of their household members, especially of their children. Despite the availability of rice and rice-related technologies, farmers’ adoption of these technologies particularly knowledge-intensive technologies, remain low. Thus there is a need to understand farmers’ constraints to adoption and how these constraints can be overcome as well as develop strategies or research design which involves farmer participation.
    In my presentation, I will share my efforts (research and training) efforts as well as failures and successes, as a social scientist, in bridging farmers and scientists and in ensuring that rice science benefit the target clients – poor rice farming communities, including men and women.

    PhD Student - Chemical Engineering
    Stanford University

    1000H, Friday, 06 June 2014
    PBGB Conference Room 1

    Abstract
    A pressing goal of plant science is to extend functional genomic tools from Arabidopsis to crops and medicinal plants. Dietary plants produce antimicrobial metabolites known as phytoalexins when stressed, which help the plant to resist disease and also often possesses drug-like effects in humans. To elucidate the genes of a new biosynthetic pathway, we selected Brassica rapa (Chinese cabbage), which produces a variety of nitrogen- and sulfur-containing phytoalexins not found in Arabidopsis. Knowledge of certain pathway intermediates led us to conjecture that cytochrome P450 (CYP) enzymes catalyze key steps. To identify candidate genes, we profiled the transcriptome of leaves exposed to microbial elicitors using RNA-seq. In vitro biochemical studies indicate that two highly similar CYP enzymes catalyze divergent steps in phytoalexin biosynthesis and multiply the chemical diversity of the defense response. Currently, we are progressing to characterize the entire pathway, for which no biosynthetic gene was previously known. Our findings reveal the evolutionary plasticity of plant specialized metabolism, and testify to the power of functional genomic techniques to uncover pathways important to plant and human health.  :: IRRI Events

    Abstract

    The Seed health Unit of the International Rice Research Institute has been designated as the single gateway for safe and efficient germplasm exchange. As the single gateway, all incoming and outgoing rice seeds, nonseed biological materials, soil samples, and seeds other than rice pass through the SHU for phytosanitary certification and/or post-entry clearance. SHU ensures compliance to import regulations and established policies in intellectual property rights. To meet the standards, dry seed inspection, routine seed health testing, crop health inspection, and seed treatment are performed on incoming and outgoing germplasm. In addition, to comply with the established intellectual property rights, all incoming and outgoing germplasm are accompanied by an appropriate material transfer agreement. However, a few concerns affect the safe and efficient movement of germplasm, making SHU’s task challenging. The three major areas of concern are the changes in: (1) the intellectual property rights environment, (2) plant quarantine requirements, and (3) the research environment at the Institute.  :: IRRI Events

    Baghdad, IRAQ



    Abstract: Root zone hydrology is an important scientific issue for agricultural water management. The processes of distribution and redistribution from both irrigation and shallow ground water occurs mostly under unsaturated conditions . Determination of flow velocity and direction are required for field assessment of the components of the soil water balance in the vadose zone. In a field study, irrigation water was applied to three different irrigation depths 30, 30-60 and 60 cm at three different depletion rates 50%, 70% and 90% from plant available water. ETcum of wheat ranged from 428.49 to 522.12 mm. Contributions to the ETcum from applied irrigation water ranged from 334.20 to 496.50 mm and increased with increasing irrigation depth. Contributions to the ETcum from upward flux capillarity ranged from 25.61 to 96.59 mm and decreased with increasing irrigation depth. Contributions to the ETcum from applied irrigation water decreased with increasing depletion rate whilst contributions to the ETcum from upward flux capillarity increased with increasing depletion rates. Daily rate contribution to evapotranspiration from irrigation water ranged from 2.15 to 3.20 mm.d-1 and from capillary flux ranged from 0.16 to 0.61 mm.d-1. :: IRRI Events

    Abstract

    DNA methylation is one of the most central elements of gene silencing among eukaryotic systems. Plants employ repressive viral genome methylation as an epigenetic defense against viruses. The accumulation of the rice tungro baciliform virus (RTBV) was found to be suppressed in rice cv. Utri Merah. Genetic analyses for the trait suppressing RTBV (RTBV resistance) in Utri Merah showed that, RTBV resistance is a dominant trait controlled by two genes, one (TBV1) of which is mapped in the 200-kb region (31.2-32.4 Mb) of Chromosome 4. The TBV1 locus includes two genes for gene-silencing, AGO2 and AGO3. To characterize the molecular mechanism of RTBV resistance, the methylation status of the RTBV genome in susceptible and resistant plants was examined using strategies based on DNA bisulfite modification. The results showed higher methylation levels in the resistant plant than in the susceptible one, in parts of ORF3, ORF2, and the large intergenic region of the RTBV genome. In addition, a portion of ORF3, which corresponds to the putative viral movement protein, was hypermethylated. The accumulation of RTBV DNA and transcript significantly decreased at 14 and 21 dpi in the resistant plant, compared with that in the susceptible plant. Collectively, our results suggest that the level of DNA methylation might be correlated with resistance to RTBV in Utri Merah. :: IRRI Events

    Abstract

    Quantitative trait locus (QTL) analysis is an effective approach to identify the multiple loci that are responsible for a trait. Detected locus identified by QTL analysis can be used in marker-assisted selection in breeding. The recent rapid development of genetic information, including high-density single nucleotide polymorphism (SNP) genotyping, facilitates genome-wide association studies (GWAS) approach and, thereby, the identification of candidate genes. GWAS can also be effective in closing the gap between QTL analysis and marker-assisted selection.
    QTL analysis and GWAS approach seem fruitful in abiotic stress (heavy metal, extreme temperatures, etc.) tolerance mechanisms in plants (Arabidopsis thaliana, Oryza sativa L., etc.).
    We performed QTL and GWAS in the model plant Arabidopsis thaliana to study the toxicity of heavy metals in the root system. Our findings suggest that toxicity of heavy metals in the root system of Arabidopsis thaliana are partly shared by those for hydrogen peroxide resistance.
    We also performed QTL analyses in rice to study the adaptation mechanisms of extreme temperatures. Lengths of anther dehiscence play an important role in the stable pollination and seed set under high temperatures. Long dehiscence helps the drop of pollen from the anther onto the stigma and enables stable pollination under high temperatures. We detected some QTLs associated with phenotypic variation in anther dehiscence and proved their reliability using chromosome segment substitution lines.
    We are now conducting a GWAS experiment for the phenotypic variation of anther dehiscence in 332 rice accessions collected from 82 countries. High-quality, custom-designed 44,100-SNP marker information is now available for those 332 rice accessions. GWAS for anther dehiscence might clarify the precise genetic interpretation for extreme temperature tolerance in rice. :: IRRI Events

    Seminar: SSD Gender mainstreaming in agricultural research: Evidence from a household survey in coastal Bangladesh

    Abstract

    Mainstreaming gender in agricultural research has remained a key priority for the CGIAR funded research and development programs. The CGIAR Gender Research Network has recently issued a ‘minimum standard guideline’ that criticizes the traditional approach of conducting gender studies by comparing male- versus female-headed households. The guideline recommends random selection of a male or a female farmer to foster a better understanding of gender gaps in agriculture. In this context, we present our experience of a gender inclusive household survey from coastal Bangladesh which included a sample of 30 percent women farmers. The objective of the study was to understand maize farmers’ preferences for index-based, savings-linked weather insurance products. Hypothetical product bundles ranging from pure insurance to pure savings containing a mix of savings and insurance were offered to the farmers using a choice experiment framework. The findings reveal a significant preference heterogeneity across the male and female farmers in terms insurance demand and the traits of the insurance contract. These findings imply that weather insurance products need to be differently designed and priced to attract women farmers. We conclude that gender inclusive research is eminent for guiding socially sustainable and equitable agricultural policy. Finally, our experience of reaching out to the sampled women farmers who lived and operated within the boundary of a conservative and patriarchal society suggests that pragmatic and adaptive field management practices are important for mainstreaming gender in agricultural research. :: IRRI Events

    Seed Division Compound, Gyogone, Insein, Yangon, Myanmar


    Abstract: In Myanmar, Bandicota bengalensis is the main rodent pest and is ranked as the second most important constraint to production in lowland rice ecosystems. Previous studies in Myanmar reported weeds can provide a refuge area and alternative food source (seeds) for rodents during their breeding season. Further, weed growth and survival may increase in the open space created when rodents damage rice crops. However, little is known about the interaction of weeds and the population dynamics of rodent pests in rice-based cropping systems in South East Asia. In 2012-2013, a study was conducted in Bago Region, Myanmar to examine the relationship between weed and rodent interactions. A replicated study (n=4) compared 4 treatments (rodents and weeds; no rodents and weeds; rodents and no weeds; no rodents and no weeds). Hand weeding was undertaken when necessary in best weed management plots (BM). We examined rodent damage, rodent population dynamics, yield loss caused by rodents, the relative abundance of different weed species, and the biomass of weeds from BM and FM (farmer management for weed managemet). The common weed species was Echinochloa crus-gali. The abundance index of rodents in BM was lower than that in FM. Rodent damage in BM (7%) plots was significantly lower than in FM plots (17%). The mean yield loss caused by rodents and weed was 8%. Our study provides clear evidence of a positive relationship between weed biomass and rodent abundance. Weed control in and around rice fields combined with coordinated community trapping of rodents during the tillering stage of rice, are recommended management options. :: IRRI Events

    Abstract

    In the last few decades, agricultural and urban runoff has had increasingly severe downstream impacts on marine and fresh water ecosystems, such as large-scale algal blooms. Since the 1970s, the region of Brittany in France, has been the hardest hit area in Europe with green tides of the genus Ulva. These algae produce polyphenols known as catechins which act as antioxidants. Many studies have shown the potential health properties of polyphenols on humans, mainly as antioxidants, anti-allergic, anti-inflammatory, anticancer, antihypertensive, and antimicrobial agents.
    Previous work demonstrated that a chemical modification of the surface of non-woven cellulosic fiber filters by fixing catechin extracted from algae reduce 62% the viral concentration of T4 bacteriohage. Proteomic experiments were performed to quantify the potential protein target of catechin on viruses.
    In the first part of the work, we used an adapted protocol (precipitation and centrifugation through CsCl gradients) for bacteriophage T4 proteins extraction. This approach allowed the identification of 54 proteins which constitute the most exhaustive proteome currently published for this virus. The second part of the work was a differential quantitative proteomic analysis of the phage T4 under exposure to different concentrations of catechin using Label-free LC-MSMS approach. The results showed that for catechin concentrations below 1mg.cm-3 the viral protein recovery was nearly the same. In contrast, at 6.3mg.cm-3, there is a drastic decrease of virus recuperation. A 2 to 3 log reduction of viral protein can be detected.
    This knowledge about T4 assembly and the antiviral properties of the algae polyphenols is very useful to the development of novel vaccines, gene and protein delivery devices, and various other biomedical applications. :: IRRI Events

    Seminar: CESD Impact of small rodent outbreaks in agriculture and human health –
    forecasting short and long-term outbreak risk


    Dr. Jens Jacob
    Federal Research Centre for Cultivated Plants
    Vertebrate Research - Leader of Rodent Research
    German Ministry of Agriculture.
    Münster, Germany


    Rodent species are vital elements of agricultural and forest habitats. However, rodent population outbreaks can interfere with human interest in cropping and public health protection. In Germany, common voles (Microtus arvalis) are the main vertebrate problem species in agriculture and bank voles (Myodes glareolus) are highly relevant for human health because they can transmit zoonoses such as Hantavirus (Puumala virus) infections to humans.

    Populations of common voles have been fluctuating dramatically probably for hundreds of years in several German regions and the same is true – although amplitudes are lower – for bank voles. Both damage to agricultural crops and effects on human health seem density dependent.

    Particular weather scenarios precede outbreaks of both species and can be used for predictions of outbreak risk. Climate change is likely to alter weather patterns and associated outbreak risk in the future. Predicting short and long-term outbreak risk can help farmers and health officials to prepare for risk situations and allow authorities to develop long-term strategies how to cope with the impact of small rodent outbreaks in the more distant future.

    In this presentation outbreak patterns and the consequences for cropping and public health will be summarised and discussed. Forecast models and predictions relevant for the next cropping season as well as long term results (years 2030-2100) will be presented. I also will present some ideas for possible collaborative research with IRRI in Asia. :: IRRI Events

    IRRI

    Abstract: New functions accounting for plant responses to salinity were integrated in the latest released version of the rice crop Model ORYZA v3, allowing its application to quantify the contribution of different crop management on rice yield variability when grown in saline soil. This seminar will present the model improvement and enhanced ability of the modified ORYZA v3 model in simulating rice growth and yield under salt-stress condition. Model sensitivity analyses were done to evaluate the relevance of the used formalism parameters to characterize salt-tolerant rice and scenario analyses were performed to identify adaptative strategies to improve and maintain the productivity of the rice-based cropping systems under saline conditions. Potential opportunities for improved representation of salinity effects on rice crop phenology and biomass partitioning remain, however, the improved ORYZA model offers a more reliable tool in assessing risks and evaluating management options for salt-affected areas. :: IRRI Events

    Abstract

    PBGB is in the business of developing improved varieties suitable for major rice ecosystems: irrigated, rainfed lowland, upland-aerobic, adverse soils, and temperate conditions. It utilizes biotechnology tools and conventional breeding strategies to discover genes underlying major traits for biotic and abiotic stresses, yield and agronomic traits, and cooking and nutritional quality, and then transferring them into productive breeding lines. For PBGB to achieve its objectives, it should know how to manage its risks and opportunities.

    In this presentation, PBGB risks that include operational/business risks, compliance risks, and occupational health and safety risks will be discussed, as well as the mitigations and internal controls to manage these risks. IRRI’s Risk Appetite, which involves IRRI’s attitude to risk taking, will also be presented. :: IRRI Events

    High Ganges River Flood Plain of Bangladesh

    PhD Research Scholar

    Bangladesh Agricultural University

    Abstract: Because of the decreasing availability of labor and water, farmers in many Asian countries are adopting dry seeded rice (DSR). DSR can be established directly in the field with no prior tillage (zero tillage) or following dry tillage (reduced tillage). Dry seeding readily enables mechanization of rice crop establishment, reducing labor requirement, and reduces irrigation water requirement for crop establishment through elimination of puddling and transplanting. However, weeds are a major constraint to its success when grown under non-ponded conditions. Herbicides are considered the best tool to manage weeds in DSR, however, due to environmental concerns and the development of herbicide resistance, sole dependence on herbicides is not sustainable in the long-run. Therefore, weed management in DSR needs an integrated approach which might include the use of high seed rate, appropriate fertilizer management and variety characteristics, and hand weeding combined with the use of herbicides. Agronomic management in DSR, such as sowing date, seed rate, water management, and fertilizer management vary countries to countries. In Bangladesh, boro (dry season rice) and aman (wet season rice) are the two major rice crops. However, cool temperature in the dry season, and high and unpredictable rainfall in the wet season are major challenges for successful establishment of DSR. Therefore, a series of agronomic and weed management experiments on DSR was conducted on the High Ganges River Flood Plain of Bangladesh. These experiments included evaluation the effects of sowing date, seeding rate, and nitrogen fertilizer management, and their interactions with weed management options, and weed dynamics and crop yield. In this seminar, key findings from this research, and recommendations for the successful establishment and growth for DSR in Bangladesh will be presented. :: IRRI Events

    Montpellier SupAgro/France




    Abstract
    The objective of the research is to analyse socio-economic, cultural and environmental aspects of planting heirloom rice varieties. The research also aimed to investigate existing and potential value chains supplying heirloom rice to local, domestic and international markets. Moreover, it (also) aimed to suggest actions that could strengthen value chains.
    According to the surveys and interviews, planting of heirloom rice varieties has declined over the last 25 years, due to several reasons such as low yield, decreasing number of family labour etc. On the other hand, organic heirloom rice production has increased after being introduced to the international market in 2006.
    In order to organise farmers to produce and process heirloom rice for the international market, the RTFC (Rice Terraces Farmers’ Cooperative) was established, supported by Self Help Groups (SHG). However, currently these groups are not working efficiently due to the lack of organisational skills of the farmers. The organisational structure of RTFC and SHGs should be strengthened to foster collective action and to build more structured value chains supplying local and domestic markets, instead of focusing solely on the international market.
    Consequently, it is evident that creating a continuous and stable market (both domestic and international) is required to sustain heirloom rice production for the long term. One of the ways to achieve this aim is by adopting a “value chain approach” which focuses on end-markets for the products and attempts to identify the most efficient business model (farming, milling, processing, packaging, and delivery) that enables farmers to serve these markets and improve their livelihood. Furthermore, this approach enables farmers to respond to market opportunities and increases competitiveness of heirloom rice in domestic and international markets. :: IRRI Events

    Seminar: SSD The effects of governance on relational and formal contracts: theory and evidence from groundwater irrigation markets

    Abstract
    We attempt to generalize Hayami and Otsuka's (1993) well known theory of land tenure contracts and connect it with Tushaar Shah's work groundwater irrigation markets. To do this we use relational contract theory combined with new field data from Bangladesh. We investigate the relationship between contract enforcement and contract structure in the market for groundwater irrigation along with the role of farmer risk preferences and production uncertainty. Governance in this market differs across villages, with some villages providing strong third party enforcement of contracts, others providing weak third party enforcement, and still others providing no third party enforcement at all. This environment allows us to examine not just the determinants of contract choice under a specific governance regime but to determine how changes in governance affect contract choice. We modify an existing relational contracting model to integrate stylized observations from the field. This model generates useful comparative static predictions for empirical testing. Using a unique data set on groundwater contracts in Bangladesh, we find individuals adopting formal contracts when high-quality third party verifiable information exists and when the punishment for contract violation is severe.

    Abstract

    The Australian Centre for Plant Functional Genomics (ACPFG) is applying forward and reverse genetics approaches to identify QTL and genes to enhance stress tolerance and yield in wheat. Drought, heat, and soil problems, such as salinity and boron toxicity, are major constraints to wheat productivity in Australia and globally. The identification of first high-value genes that enhance and stabilize yield under stress are now showing the potential of genomics and molecular breeding to support our efforts to enhance crop productivity and keep up with the increasing demand on food production.
    At the same time it is necessary to enhance nutrient-use efficiency to reduce farm inputs, especially for nitrogen and phosphorus. Although the complex N- and P-related pathways are well-studied in other crops, this is still a difficult and pioneering endeavour in wheat due to the complexity of the wheat genome and the underlying pathways.  :: IRRI Events

    a new paradigm in crop improvement

    Abstract: Sugars produced in photosynthesis provide the energy and building blocks for growth, development and plant, crop and ecosystem productivity upon which all life and agricultural production depends. Sucrose is the dominant sugar found in plants. Another similar disaccharide, trehalose, previously thought to be of no great consequence in plants has been found to have an essential interrelationship with sucrose, but as regulator and signal of sucrose availability. The sucrose/trehalose 6-phosphate interrelationship is uniquely developed in plants. This is because of the need to relate sucrose produced in photosynthesis to growth and development in fluctuating environments. Sinks that utilize assimilate are more sensitive to environmental perturbations, with the exception of the light environment, than photosynthesis. Building on our seminal advance that trehalose 6-phosphate (T6P) inhibits the feast/famine protein kinase, SnRK1, we show the importance of T6P/SnRK1 in timing of gene expression for growth responses to different environments: grow-stop-regrow responses. This mechanism underpins engineering crops for yield resilience. As well as responding to sucrose, T6P can also direct sucrose allocation, as a determinant of sink strength, which may key in increasing yield potential. Results will be presented that show the benefits of either increasing or decreasing T6P in different cells at different times in different environments. :: IRRI Events

    Abstract

    Wild rice species possess traits which are desirable to introduce into commercial cultivars. To do so one must first identify the genes controlling that trait. In our project we try to find key genes for the formation of rhizomes in the wild African rice variety Oryza longistaminata. The formation of rhizomes leads to increased biomass and yield and is furthermore seen as a prerequisite for the development of perennial rice.

    In one approach to identify genes controlling rhizome growth, Ol was crossed to the commercial, non-rhizome producing cultivar Nipponbare (Oryza sativa subsp. japonica). Previous analyses indicated that multiple loci contribute to rhizome formation. To speed up marker development and to increase our ability to detect QTLs we combined the power of NGS technology and classical marker-assisted breeding by performing genotyping-by-sequencing (GBS). This allowed fast, cost-effective genotyping of hundreds of individuals at an unprecedented number of SNP markers. Using the MiSeq platform and multiplexed runs of 32 individuals we sequenced defined regions of the genome of 303 F2 individuals of a Nipponbare x Oryza longistaminata cross, including the corresponding parents. This resulted in 0.66 x 106 reads per individual. Those data was subsequently used to detect SNPs between the two parents which will be used as genetic markers. So far, an analysis of 185 individuals resulted in 5,518 SNPs that passed all filters and were thus deemed useful markers for subsequent QTL detection. This talk will focus on the development of a suitable GBS pipeline based on the TASSEL software. :: IRRI Events

    Seminar: CESD Can rice yield gaps be closed? A theoretical framework to explain yield gaps at farm level with a case study for Central Luzon, Philippines

    Abstract
    Rice yield gaps, defined as the difference between climatic potential yield and farmers’ yields, have been estimated to be over 3 ton ha-1 in major rice-based farming systems across Southeast Asia. It is crucial to understand from a farm and farming system perspective why such large yield gaps exist and to assess under which circumstances they can be closed. For that purpose, a generic theoretical framework which decomposes the yield gap into an efficiency, resource and technology yield gap will be introduced. Each of the aforementioned yield gaps can be explained in a consistent manner using a combination of agronomic (crop modelling; ORYZAv3) and economic (frontier analysis) methodologies applied to farm-level data. By doing so, it is possible to assess in a systematic way the contribution of crop management, technological innovations and farmers’ objectives and constraints to the rice yield gap. Some preliminary results of an empirical application of this framework and methodologies using a farm household survey in Central Luzon will be presented and discussed in this seminar.  :: IRRI Events

    Abstract

    Increasing yield is the most important target in rice breeding program. We have been trying to increase the yield potential through introducing/pyramiding of known yield-related genes regulating grain number per panicle, culm strength, grain size, and grain weight. Nine genes (Gn1a, SPL14, SCM2, GS5, GW5, Ghd7, DEP1, TGW6, and SPIKE) are being introduced into 12 elite indica rice cultivars (eight IRRI varieties and four CIAT varieties). For marker-assisted breeding, we developed PCR-gel based markers for each gene. Through marker analysis we obtained single gene introgression lines in BC3F1 generation and also some gene pyramided lines from crosses with multiple donors (F1 x F1 or BC1F1 x F1). The procedure, current status, and further plan will be presented at the seminar. :: IRRI Events

    Abstract

    Arabidopsis thaliana has served as a model species for the study of the architecture and function of the circadian clock. We are exploring natural variation in clock functions and have developed an automatic and high-throughput motion estimation system to measure circadian parameters by leaf movement. Analysis of a nested association mapping (NAM) panel from seven Recombinant Inbred Line (RIL) populations, supplemented with accessions from the 1001 Genomes Project, has identified multiple Quantitative Trait Loci (QTL) linked to known clock genes, as well as at least one novel QTL not associated with any known clock genes.

    Experimental disruption of the clock via large-effect mutations reduces fitness. Therefore, it is of both academic and practical interest to explore the extent to which the circadian clock model developed in Arabidopsis can be generalized to other plants, especially crop plants, and to ask whether manipulation of the circadian clock can enhance agricultural yield. Accordingly, we have extended our studies to Brassica rapa, an agricultural crop closely related to Arabidopsis. We have mapped QTL for circadian period, water use efficiency (WUE), shade avoidance, and other morphometric traits. There is striking colocalization of QTL for circadian period with QTL for shade avoidance and WUE and the genetic underpinning of these differences is of considerable interest. To enhance our investigations, we have initiated a breeding program to develop a NAM population for B. rapa, using an oilseed as the common female parent, and to date have added a second RIL population to our initial analysis.

    We have explored variation in circadian function among natural populations of Mimulus guttatus and elite cultivars of soybean (Glycine max). We observe a strong latitudinal cline in circadian period in both species. This suggests that both natural and artificial selection have acted on the circadian clock and strongly suggests that the clock contributes to performance in both natural and cultivated conditions. This is consistent with our growing understanding of the roles of the clock in the regulation of flowering and in the temporal coordination of growth and development, and in abiotic and biotic stress responses. :: IRRI Events
