[Construction of expression vector with antisense Rubisco activase gene and its genetic transformation in rice].

In this research, Rubisco activase gene (rca) was amplified using specific primers and inserted into pGEM T-easy vector, and then cut with EcoRI after confirming by sequencing. The fragment was subcloned into pBluescript KS+, digested with the enzyme BamHI and inserted into the binary expression vector pCAMBIA1301, and the resulting construction with antisense rca was named pCAMR02. The pCAMR02 vector was introduced into Agrobacterium tumefaciens strain EHA105 by electroporation and transformed to embryos of rice (Oryza.
