Abstract:

Photorespiration is known as the light-dependent absorption of the O2 and release of CO2 response by plant green cells, whose strength is an important factor affect the level of the photosynthetic efficiency of C3 and C4 plants. The study of the molecular mechanism of photorespiration is one of the hot-topics of research on photosynthesis. In the article, the research on photorespiratory metabolic pathways, the expression and regulation of photorespiratory genes and the progress of screen of photorespiration mutants were summarized. The biological function of photorespiration was discussed and the prospect of photorespiration was also provided.
