DgcA, a diguanylate cyclase from Xanthomonas oryzae pv. oryzae regulates bacterial pathogenicity on rice
Xanthomonas oryzae pv. oryzae (Xoo) is the causal agent of rice blight disease as well as a serious phytopathogen worldwide. It is also one of the model organisms for studying bacteria-plant interactions. Current progress in bacterial signal transduction pathways has identified cyclic di-GMP as a major second messenger molecule in controlling Xanthomonas pathogenicity. However, it still remains...
متن کاملA LuxR homologue of Xanthomonas oryzae pv. oryzae is required for optimal rice virulence.
SUMMARY In Gram-negative bacteria a typical quorum sensing (QS) system usually involves the production and response to acylated homoserine lactones (AHLs). An AHL QS system is most commonly mediated by a LuxI family AHL synthase and a LuxR family AHL response regulator. This study reports for the first time the presence of a LuxR family-type regulator in Xanthomonas oryzae pv. oryzae (Xoo), whi...
متن کاملAntagonistic Interactions Between Strains of Xanthomonas oryzae pv. oryzae.
ABSTRACT The ability of some phytopathogenic bacterial strains to inhibit the growth of others in mixed infections has been well documented. Here we report that such antagonistic interactions occur between several wild-type strains of the rice bacterial blight pathogen Xanthomonas oryzae pv. oryzae. In mixed inoculations, a wild-type Philippine strain was found to inhibit the growth of a wild-t...
متن کاملMolecular determinants of disease and resistance in interactions of Xanthomonas oryzae pv. oryzae and rice.
Xanthomonas oryzae pv. oryzae is the causal agent of rice bacterial blight disease. Numerous genes critical for virulence have been identified. This article reviews current knowledge on the molecular mechanisms of X. oryzae pv. oryzae virulence.
متن کاملEctopic expression of rice Xa21 overcomes developmentally controlled resistance to Xanthomonas oryzae pv. oryzae.
Recognition of pathogen-associated molecular patterns (PAMPs) by pattern recognition receptors (PRRs) activates the innate immune response. The rice PRR, XA21, confers robust resistance at adult stages to most strains of the bacterial pathogen Xanthomonas oryzae pv. oryzae (Xoo). Seedlings are still easily infected by Xoo, causing severe yield losses. Here we report that Xa21 is induced by Xoo ...
