Antagonistic 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 کاملA Novel Manganese Efflux System, YebN, Is Required for Virulence by Xanthomonas oryzae pv. oryzae
Manganese ions (Mn(2+)) play a crucial role in virulence and protection against oxidative stress in bacterial pathogens. Such pathogens appear to have evolved complex mechanisms for regulating Mn(2+) uptake and efflux. Despite numerous studies on Mn(2+) uptake, however, only one efflux system has been identified to date. Here, we report on a novel Mn(2+) export system, YebN, in Xanthomonas oryz...
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 کاملCitB is required for full virulence of Xanthomonas oryzae pv. oryzae.
To identify novel virulence associated genes in Xanthomonas oryzae pv. oryzae (Xoo), a Xoo isolate (XooIR42), obtained from north of Iran, was selected to generate a mini-Tn5 transposon mutation library. One mutant (XooM176) that indicated reduced virulence on rice plants, while grew similar to wild type was selected. This mutant had an insertion in a coding region with 96% amino acid identity ...
متن کاملEffector Diversification Contributes to Xanthomonas oryzae pv. oryzae Phenotypic Adaptation in a Semi-Isolated Environment
Understanding the processes that shaped contemporary pathogen populations in agricultural landscapes is quite important to define appropriate management strategies and to support crop improvement efforts. Here, we took advantage of an historical record to examine the adaptation pathway of the rice pathogen Xanthomonas oryzae pv. oryzae (Xoo) in a semi-isolated environment represented in the Phi...
