Abstract
Burkholderia plantarii is a plant pathogen responsible for causing rice seedling blight. The molecular mechanisms responsible for this pathogenicity are currently unknown. In this study, we report the identification and characterization of N-acyl homoserine lactone quorum sensing and the stationary phase RpoS sigma factor of B. plantarii. Both global regulatory systems are involved in causing rice seedling blight. This is the first report of gene regulators of B. plantarii implicated in the disease.
