Convergent molecular evolution of phosphoenolpyruvate carboxylase gene family in C₄ and crassulacean acid metabolism plants.

ABSTRACT: 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 photosynthesis in vascular plants. However, the integral evolutionary history and convergence of PEPC in plants remain poorly understood. In the present study, we identified the members of PEPC gene family across green plants with seventeen genomic datasets, found ten conserved motifs and modeled three-dimensional protein structures of 90 plant-type PEPC genes. After reconstructing PEPC gene family tree and reconciled with species tree, we found PEPC genes underwent 71 gene duplication events and 16 gene loss events, which might re
