Convergent molecular evolution of phosphoenolpyruvate carboxylase gene family in C4 and crassulacean acid metabolism plants [PDF]
PeerJ, 2022 Phosphoenolpyruvate carboxylase (PEPC), as the key enzyme in initial carbon fixation of C4and crassulacean acid mechanism (CAM) pathways, was thought to undergo convergent adaptive changes resulting in the convergent evolution of C4 and CAM ...
