The C4 Rice Project is one of the scientific “Grand Challenges” of the 21st Century. With Phase 3 now well underway, the C4 project has undergone some dramatic changes. We may appear leaner but our mission to supercharge the rice engine remains steadfast. In this latest installment to the C4 rice story, we scale down the hype to provide an honest and frank assessment of the progress made at IRRI so far. We will share our successes with engineering C4 biochemistry into rice, the difficulty in the search for genes controlling C4 leaf anatomy, and the promise of our latest novel high-throughput mutant screens. We will discuss with you the numerous technical and scientific challenges that have had to be addressed. These include how to measure C4 metabolic fluxes in rice and new ways of identifying the genes controlling C4 leaf anatomy. We present the use of phenomics tools in our genetic screens and discuss the potential application of these across IRRI. There remains much more work to be done before we can deliver upon the potential grain yield increases that C4 photosynthesis offers. We give some perspectives on the results to date, together with some of the wider contributions of the project to the future of rice research. We extend a warm invitation to you all.
