[Objective] The aim was to isolate the CBL-interacting protein kinases(CIPK)from maize(Zea mays L.)and construct the fusion gene expression vector which consisted the ZmCIPK8 and GFP.[Method] The ZmCIPK8 cDNA was successfully cloned by using RT-PCR method.And then,it was connected to the pBlueScript SK(pSK)plasmid,which contained the GFP gene.So that the fusion gene vector pSK-CIPK-GFP was obtained.Then,the fusion gene was connected into the efficient plant expression vector PBI121 to construct the fusion gene expression vector PBI-CIPK-GFP.At last,the recombined expression vector was transformed to Agrobacterium tumefaciems LBA4404 to produce the engineering strain LBA4404-PBI-CIPK-GFP.[Result] The fusion gene expression vector which consisted of GFP and ZmCIPK8 gene and engineering strain LBA4404-PBI-CIPK-GFP were successfully constructed.[Conclusion] The results lays a foundation for further study of subcellular localization of ZmCIPK8,which can help to clarify the molecular mechanism of regulation serious stresses,and also provides an important basis for the research on resistance stress engineering of maize.
