The sensor histidine kinase PhcS participates in the regulation of quorum sensing-dependent virulence genes in Ralstonia pseudosolanacearum strain OE1-1

ABSTRACT Ralstonia pseudosolanacearum strain OE1-1 secretes methyl 3-hydroxymyristate (3-OH MAME) as a quorum-sensing (QS) signal. Strain OE1-1 senses the chemical by the sensor histidine kinase PhcS, leading to the activation of the LysR family transcriptional regulator PhcA. The activated PhcA con...
