“…Xoc was first reported in the Philippines in 1918 ( 4 ). Upon entering rice leaves through wounds or stomata, Xoc colonizes the interstices of mesophyll cells, resulting in leaf lesions ( 5 ) and yield losses of up to 32% ( 6 ). Considering its high virulence toward Zhonghua 11 and other frequently used rice varieties, we sequenced and assembled the complete genome of Xoc strain HB8, which serves as a valuable resource for analyzing bacterial pathogenesis and interactions in the Xanthomonas -rice pathosystem.…”

“…T3SS plays a crucial role in both plant and animal pathogens successfully infected into the host [12,13]. As with many other bacterial pathogens, T3SS, which is encoded by a cluster of over 20 hypersensitive response and pathogenicity (hrp) genes, is an essential virulence determinant of X. oryzae [14,15]. Mutations in the T3SS gene in X. oryzae result in loss of the ability to elicit its hypersensitive response (HR) in the nonhost plant Nicotiana benthamiana.…”

Xanthomonas oryzae pv. oryzicola (Xoc) is a notorious plant pathogen. Like most bacterial pathogens, Xoc has evolved a complex regulatory network to modulate the expression of various genes related to pathogenicity. Here, we have identified TfmR, a transcriptional regulator belonging to the TetR family, as a key player in the virulence mechanisms of this phytopathogenic bacterium. We have demonstrated genetically that tfmR is involved in the hypersensitive response (HR), pathogenicity, motility and extracellular polysaccharide production of this phytopathogenic bacterium. Our investigations extended to exploring TfmR’s interaction with RpfG and HrpX, two prominent virulence regulators in Xanthomonas species. We found that TfmR directly binds to the promoter region of RpfG, thereby positively regulating its expression. Notably, constitutive expression of RpfG partly reinstates the pathogenicity compromised by TfmR-deletion mutants. Furthermore, our studies revealed that TfmR also exerts direct positive regulation on the expression of the T3SS regulator HrpX. Similar to RpfG, sustained expression of HrpX partially restores the pathogenicity of TfmR-deletion mutants. These findings underscore TfmR’s multifaceted role as a central regulator governing key virulence pathways in Xoc. Importantly, our research sheds light on the intricate molecular mechanisms underlying the regulation of pathogenicity in this plant pathogen.
