Population biology of Xanthomonas oryzae pv. oryzae and approaches to its control uri icon

abstract

  • New insights into the population structure of Xanthomonas oryzae pv. oryzae, the pathogen causing bacterial blight of rice, have been achieved through the use of molecular markers in combination with virulence typing. A hierarchical analysis to evaluate diversity and structure of X. oryzae pv. oryzae populations between countries, between different agro-ecosystems, and within and between farmer's fields has revealed differentiation of subpopulations on various spatial scales. Such information on the pathogen populations might be used to refine disease management strategies and to investigate pathogen evolution.
