Abstract: 【OBJECTIVE】 The pyruvate-phosphate dikinase expressed effectively by utilizing leaf-specfic promoter of small subunits of rubisco; 【METHOD】The small subunits of rubisco and the gene of Pdk were digested by PstI and SalI from pRGN and pUCm-Pdk,and inserted into expression vector pCAMBI1301.Then it was transformed into EHA105 by direct entering way; 【RESULTS】The plant transformation vector p1301-Prbcs-PPDK was constructed in this experiment. The selective marker gene was Hpt(Hygomycin phosphate transferase). By digestion and PCR identification, The vector p1301-Prbcs-PPDK was transferred to Agrobacterium tumefaciens EHA105 ; 【CONCLUSION】 The pyruvate-phosphate dikinase is the key enzyme of C4 photosynthesis.The experiment constructed a expression vector suit to monocotyledon,which will provide an important experimental base for study on PPDK function..
