C4 photosynthesis is more efficient than C3 photosynthesis. A team from Biodiversity Research Center, Academia Sinica found that whole genome duplication enabled G. gynandra to undergo a C3-C4 intermediate stage, develop high vein complexity, evolve C4 enzyme genes and produce extra ATPs for CO2 concentration and finally evolved C4 photosynthesis. The study was co-guided by Prof. Sun-Ban Ku (National Chia-Yi University) and Academician Wen-Hsiung Li (Academia Sinica) and published in Molecular Biology and Evolution.
