The Development of C ₄ Rice: Current Progress and Future Challenges

Abstract

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.
