Abstract: In order to allow brassinosteroid gene BAS1 overexpress in root, the root expression vector pCAMBIA2301-RB7-rbc with root promoter TobRB7 was constructed. Then inactivated gene BAS1 was integrated into the root overexpression vector pCAMBIA2301-RB7-BAS1-rbc, and they were transformed into tobacco by Agrobactrium tumefaciems infection. With the verification by PCR and RT-PCR, the target gene BAS1 was transformed into tobacco genome successfully, and expressed in root;the expression of brassinosteroid receptor kinase gene BRI1 in roots of transgenic plants was affected.

Key words: BAS1 gene, construction of root expression vector, transgenic plants, expression
