植物光合碳同化途径关键酶基因研究

Study on the key enzyme genes of carbon fixation in photosynthetic organisms in plants

植物按照碳同化方式的不同可分为C_3途径、C_4途径和CAM途径。C4植物通过长期的进化形成了特有的高效光合基因。在高温、高光强和低CO_2浓度等条件下,C_4植物的光合速率较C_3植物更高。本文阐述了高等植物光合碳同化途径中PEPC、PPDK、NADP-ME、RCA、SBPase 5个关键酶基因研究进展。

According to CO＂ assimilation mechanisms, plants can be classified into three types such as C3, C4, and CAM. C4 plant acquired a series of high performance photosynthetic genes in evolution,which confers to more efficient photosynthesis than C3 plant under adverse conditions such as high photo-intensity, temperature, and low CO2 concentration. The research progress about five key enzyme genes in carbon fixation in photosynthetic organisms were expounded.
