[Objective] To study the physiological biochemical characteristic of Os- WRKY17 in rice and identify the subcellular location of OsWRKY17. [Method] The primer of the OsWRKY17 gene was designed according to the full-length sequence of OsWRKY17 in Genbank and was cloned by RT-PCR. The cloned fragment was then recombined with the green fluorescent protein gene of plasmid vector pBinGFP. The recombinant plasmid pBinGFP-OsWRKY17 was transformed into Arabidopsis through Agrobacterium tumefaciens strain GV3101. [Result] Colony PCR and diges- tion identification proved that the plant expression vector pBinGFP-OsWRKY17 was successfully constructed by the fusion of OsWRKY17 and GFP, and the expression vector was successfully transformed into the genome of Arabidopsis, there by ob- taining a resistant plant. [Conclusion] The construction of OsWRKY17 expression vector established the foundation for study on the physiological the biochemical char- acteristics of QsWRKY17.
