  • 7th International Rice Blast Conference Rice blast disease remains the most destructive disease of cultivated rice worldwide. Considering that rice is the staple food for more than half of the human population, the disease is a significant threat to food security for many nations. It is, therefore, imperative to devise the novel and stable control strategies for the disease, which requires an understanding of the pathogen, rice blast fungus, and its interaction with rice or other host plants. The International Rice Blast Conference (IRBC) has been the forum to foster collaboration in rice blast research among scientists around the world. Not surprisingly, much progress has been made on the research of the biology, genomics, host-pathogen interactions, resistance, and disease management of rice blast since the last IRBC in Jeju, South Korea, in 2013. To share recent advancements in the scientific research and broaden our understanding of the disease, we host the IRBC07 in Manila, Philippines.

  • 01:15pm - 02:15pm  Seminar: CESD Lotus LysM receptors and their role in microbial perception

    Abstract: Plants are constantly exposed to both beneficial and pathogenic microbes, and the interaction with these microorganisms may be vital for plant survival. Characterization of legume mutants has shown that a common genetic program is required for interaction with both rhizobia and arbuscular mycorrhizal (AM) fungi leading to symbiotic nitrogen fixation or mycorrhizal root colonization that enhance the plants nitrogen and phosphor uptake, respectively. Recent results show that plant receptor proteins containing the carbohydrate-binding LysM-motif are involved in the recognition and discrimination of rhizobia from pathogenic microbes while recognition of AM fungi have remained unknown. A large family of LysM receptor-like kinases has been identified in the model legume Lotus japonicus. Many of these genes have not yet been functionally characterized, however, the two LysM receptor-like kinases (LjNFR1 and LjNFR5) are key molecular components required for perception of the lipochitooligosaccharide (LCO) signalling molecules (Nod factors) produced by rhizobia, and for the initiation of signalling events leading to symbiotic nitrogen fixation. Recent studies revealed that AM fungi also produce LCOs and short-chain chitin oligomers that are recognized by legume hosts, and elicit similar physiological responses in plant cells as Nod factors. However, the receptor(s) for these AM produced signalling molecules remain unknown.
    I will present our current understanding and latest results on the involvement of LysM receptors during root-symbiosis with AM fungi.  :: IRRI Events
