OsWRKY26 negatively regulates bacterial blight resistance by suppressing <i>OsXa39</i> expression.

ABSTRACT: Plants are susceptible to infection by various pathogens with high epidemic potential. Xanthomonas oryzae pv. oryzae (Xoo) causes bacterial blight in rice, one of the most significant diseases in both temperate and tropical regions. In this study, we report the identification and characterization of OsWRKY26, a sucrose-inducible transcription factor, that plays a role in the plant defense responses following Xoo infection. We found that mutant plants with defective OsWRKY26 showed enhanced defense response specifically to Xoo, indicating that this transcription factor acts as a negative defense regulator. In contrast, mutant plants did not exhibit higher resistance compared to wild-type (WT) plants when infected with the rice blast fungal pa
