Bacteria respond to environmental cues through a variety of mechanisms. Two-component systems (TCSs) are a conserved mechanism used by bacteria to accurately respond and sense environmental changes. The monitoring of envelope perturbance is linked to TCS CpxA/CpxR in animal-infecting pathogens. The study of the TCS response regulator (RR) CpxR is largely unexplored in phytopathogens. This work focuses on the genetic linkage between cpxR and T3SS expression regulation. We identified the multiple roles of CpxR on several T3SS regulators and its participation in the bacterial second messenger (c-di-GMP) signaling cascade. Moreover, a compound library screening revealed a novel Cpx inducer CHIR-090, …
