Development and Validation of an SNP Marker for Identifying Xanthomonas oryzae pv. oryzae Thai Isolates That Break xa5-Mediated Bacterial Blight Resistance in Rice.

Xanthomonas oryzae pv. oryzae (Xoo) is a pathogenic bacterium responsible for bacterial blight (BB) disease in rice, primarily mediated by the interaction between the plant and pathogen. The virulence mechanism involves the activation of the Sugars Will Eventually be Exported Transporter (SWEET) gene family in rice by transcription activator-like effectors derived from Xoo.
