| Abstract: |
| Sucrose phosphate synthase (SPS) is one of the key enzymes in the synthetic pathway of sucrose, which influenced the growth, development and yield of crop. In this review, the physical and chemical character of SPS, the effects of SPS on growth, development, and yield and quality of crop, the response to the high CO2 and the control and environment of SPS in crop leaf with transgenic plant were introduced. Advance research should be focus on the analysis of the relationship between SPS and sucrose-phosphate phosphatase (SPP).The breeding of sugarcane and cassava cultivars with transgenic SPS should be studyed for producing biomass energy. |
