Research progress of crop photosynthetic efficiency adaptation to adversity and improving ways
Photosynthesis is the main driving force that sustains the growth of plants on Earth.We have made some progress in the study of physiological,biochemical and molecular regulation mechanism of photosynthesis.However,our understanding of the regulation mechanism of photosynthesis in the com-plex and changeable natural environment is still limited,so the improvement of photosynthesis in crops is low,and may even be far from its biological limit.In this paper,we summarized the abiotic stress factors(high temperature,salinity and drought)that limit photosynthetic efficiency,then discussed the ways to im-prove crop photosynthetic efficiency,and looked forward to the future prospects of photosynthesis im-provement,in order to provide a systematic and comprehensive reference for the establishment of new targets for crop photosynthetic improvement and the development of photosynthesis in improving crop yield.
