Gene and genome duplications and the origin of C4photosynthesis:Birth of a tr…

tC4photosynthesis is a trait that has evolved in 66 independent plant lineages and increases the efficiencyof carbon fixation. The shift from C3to C4photosynthesis requires substantial changes to genes andgene functions effecting phenotypic, physiological and enzymatic changes. We investigate the role ofancient whole genome duplications (WGD) as a source of new genes in the development of this …
