Cut the E8 promoter and Adketo gene and inserted into the plant binary expression vector pBI121to obtain the recombinant expression vector. And then to identify the vector by microbial PCR detection and enzyme digestion.Results: Sequencing results analysis showed the right E8 and Adketo gene sequences, the identification by microbial PCR and digestion with restriction enzymes proved that the recombinant vector had the inserts with expected length of target fragments.Conclusion: The plant expression vector containing Adketo gene driven by fruit specific promoter E8 was successfully constructed.展开更多
