HOẠT ĐỘNG CỦA PROMOTER OsNAC6 TĂNG CƯỜNG KHẢ NĂNG CHỐNG CHỊU TRÊN DÒNG LÚA VIỆT NAM CHUYỂN GEN CH1

The drought, salt and cold are unfavourable factors of the environment in reduced productivity of rice. OsNAC6 promoter activity of rice helps increase resistance to adverse conditions. OsNAC6 promoter was transformed into rice calli from mature embryos of line CH1 through Agrobacterium tumefaciens. After two consecutive selection on culture medium added 50 mg/l hygromycin were screened for 13 plants survived. Conducted artificial stress to the T1 generation seedlings through gene expression of Gus. Gus staining results of the T1 stress rice plants showed promoter OsNAC6 works well on rice, transformation experiments, regenerated rice made with this vector was successful.
