Positive regulation of the Hrp type III secretion system in Pseudomonas syringae pv. phaseolicola.

Molecular plant-microbe interactions : MPMI - 1 May 2010

Abstract excerpt

Disease in compatible hosts and induction of the hypersensitive response in resistant plants by most plant-pathogenic bacteria require a functional type III secretion system (T3SS). Expression of T3SS genes responds to host and environmental factors and is induced within the plant. In Pseudomonas syringae, expression of the T3SS requires HrpL, which is transcriptionally upregulated by HrpR and HrpS. In some...
