Using PCR-based amplification, two different restriction sites at both ends of tobacco Bax inhibitor-1 （NtBI-I） gene were created, respectively, which made the construction of ihpRNA gene silencing vector more efficiently. Then, NtBI-1 genes were inserted into Multiple Cloning Site （MCS） of pGSA2285 respectively to form Bax inhibitor-1 ihpRNA gene silencing vector, named as pGSA4285, containing sense and anti-sense BI-1 sequence which was spliced by chalcone synthase intron. Combined PCR identification and enzyme restriction analyses, the results showed that Bax inhibitor-1 ihpRNA gene silencing vector had been constructed and transferred into Agrobacterium tumefaciens EHA105 successfully, which laid a foundation for the further study on the function of BI-1 in plant PCD regulation.展开更多
