The C4 pathway of photosynthesis was discovered and characterized, more than four decades ago. Interest in C4 pathway has been sustained and has recently been boosted with the discovery of single-cell C4 photosynthesis and the successful introduction of key C4-cycle enzymes in important crops, such as rice. Further, cold-tolerant C4 plants are at the verge of intense exploitation as energy crops. Rapid and multidisciplinary progress in our understanding of C4 plants warrants a comprehensive documentation of the available literature. The book, which is a state-of-the-art overview of...
