Phaseolotoxin synthesis is regulated by the GacS/GacA two-component system

ABSTRACT: Pseudomonas syringae pv. phaseolicola is the causal agent of halo blight disease of beans (Phaseolus vulgaris L.), which is characterized by water-soaked lesions surrounded by a chlorotic halo resulting from the action of a non-host-specific toxin known as phaseolotoxin, that inhibits the enzyme ornithine carbamoyltransferase involved in the arginine biosynthesis pathway. It was previously reported that genes within the Pht cluster were involved in the regulation and synthesis of phaseolotoxin. The GacS/GacA two component signal transduction system controls important pathogenicity and virulence mechanisms in several Gram-negative bacteria. In the present study we hybridized a genomic microarray of P. syringae pv. phaseolicola NPS3121 to compare transcriptional profiles from wild type strai
