摘要

Photosynthesis started to evolve some 3.5 bil-lion years ago CO2 is the substrate for photo-synthesis and in the past 200-250 years,at-mospheric levels have approximately doubled due to human industrial activities.However,this time span is not sufficient for adaptation mechanisms of photosynthesis to be evolutio-narily manifested.Steep increases in human population,shortage of arable land and food,and climate change call for actions,now.Thanks to substantial research efforts and ad-vances in the last century,basic knowledge of photosynthetic and primary metabolic proc-esses can now be translated into strategies to optimize photosynthesis to its full potential in order to improve crop yields and food supply for the future.Many different approaches have been proposed in recent years,some of which have already proven successful in different crop species.Here,we summarize recent ad-vances on modifications of the complex net-work of photosynthetic light reactions.These are the starting point of all biomass production and supply the energy equivalents necessary for downstream processes as well as the oxygen we breathe.
