Research Abstract

Panicle blast1 (Pb1) is useful gene for rice breeding, and its protein structure is similar to that of true resistance proteins. In this study, we identified that Pb1 directly interacts with WRKY45 transcription factor and the interaction is required for the resistance. The interaction stabilizes WRKY45 protein, and enhances the defense activation.
