It is an important prerequisite that we understand systematically for assessing scientifically, alleviating limitations, increasing ability carbon assimilation. were explained systematically. responses three (biochemical limitation lb, stomatal ls, mesophyll lm) different environments analyzed, its influence mechanisms discussed emphatically. quantitative analysis methods improvement measures reviewed. Finally, following suggestions future research driven by goal improving formulated:(1) Combing genetic engineering technology system biology data improve productivity; (2) mechanism impact response speed photosynthesis; (3) Driving genes aquaporin (AQPs) carbonic anhydrase (CAs) perceive changes environmental signals. This review expected provide some references further understanding reducing nd assimilation under background change.
