De novo transcriptome assemblies of C₃ and C₄ non-model grass species reveal key differences in leaf development.

ABSTRACT:

Background

C₄ photosynthesis is a mechanism that plants have evolved to reduce the rate of photorespiration during the carbon fixation process. The C₄ pathway allows plants to adapt to high temperatures and light while more efficiently using resources, such as water and nitrogen. Despite decades of studies, the evolution of the C₄ pathway from a C₃ ancestor remains a biological enigma. Interestingly, species with C₃-C₄ intermediates photosynthesis are usually found closely related to the C₄ lineages. Indeed, current models indicate that the assembly of C₄ photosynthesis was a gradual process that included the relocalization of photorespiratory enzymes, and the establishment of intermediate photo
