The Development of C ₄ 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...
