Transformation of the BWMK1-interacting gene BWIP4.

BWMK1,a first reported rice MAPK gene,was transcriptionally activated by blast fungus infection and wounding.To make a further understanding about the BWMK1-mediated defense signaling,we identified 7 BWMK1 interacting genes by yeast two-hybrid screening,designate BWIP1~BWIP7,and selected BWIP4 for further functional characterization.Through Agrobacterium mediated transformation method,we generated overexpression and RNAi transgenic plant using a japonica cultivar nipponbare as a receptor.The GUS assay and PCR results showed that the target gene had been intergrated into receptor.Further expression analysis was confirmed by RT-PCR.These transgenic lines provided us a good material for in-deepth function analysis of BWIP4.
