Role of rpoS (katF) in oxyR-independent regulation of hydroperoxidase I in Escherichia coli.

abstract：:The bacterium Burkholderia glumae causes rice grain rot by producing toxoflavin, whose expression is regulated by quorum sensing (QS). We report a major deviation from the current paradigm for the regulation of bacterial polar flagellum genes. The N-octanoyl homoserine lactone (C8-HSL)-deficient mutant of B. glumae is...
