AsnB, regulated by diffusible signal factor and global regulator Clp, is involved in aspartate metabolism, resistance to oxidative stress and virulence in Xanthomonas oryzae pv. oryzicola.

Xanthomonas oryzae pv. oryzicola (Xoc) causes bacterial leaf streak in rice, which is a destructive disease worldwide. Xoc virulence factors are regulated by diffusible signal factor (DSF) and the global regulator Clp.

[Function of a two-component system RpfCxoc/RpfGxoc in Xanthomonas oryzae pv. oryzicola].

Objective: To elucidate the biological functions of a two-component system RpfCxoc/RpfGxoc in Xanthomonas oryzae pv. oryzicola (Xoc).

Method: Based on the genome template from Xoc wild-type strain Rs105, the rpfCxoc and rpfGxoc genes were amplified by polymerase chain reaction (PCR).

Identification and characterization of a novel gene, hshB, in Xanthomonas oryzae pv. oryzicola co-regulated by quorum sensing and clp.

Virulence factors of Xanthomonas oryzae pv. oryzicola, the causal agent of bacterial leaf streak in rice, are regulated by a diffusible signal factor (DSF)-dependent quorum-sensing (QS) system. In this study, a novel pathogenicity-related gene, Xoryp_010100018570 (named hshB), of X.

[Analysis of the flgD and figE genes regulated by diffusible signal factor in Xanthomonas oryzae pv. oryzicola].

Objective: To investigate functions of flgDxoc and flgExoc genes regulated by diffusible signal factor (DSF) in Xanthomonas oryzae pv. oryzicola(Xoc)Rs105.

Methods: TheflgDxoc and flgExoc genes were amplified by PCR.

Proteomic analysis of the regulatory function of DSF-dependent quorum sensing in Xanthomonas oryzae pv. oryzicola.

Xanthomonas oryzae pv. oryzicola (Xoc), which caused bacterial leaf streak in rice, is a bacterial pathogen limited to the apoplast of the mesophyll tissue. The rpfF that encodes diffusible signal factor (DSF) synthase, played a key role in the virulence of many plant pathogenic bacteria.
