The Development of C4 Rice: Current Progress and Future Challenges

Another green revolution is needed for crop yields to meet demands for food. The international C-4 Rice Consortium is working toward introducing a higher-capacity photosynthetic mechanism-the C-4 pathway-into rice to increase yield. The goal is to identify the genes necessary to install C-4 photosynthesis in rice through different approaches, including genomic and transcriptional sequence comparisons and mutant screening.
