Functional Characterisation of the Quorum-Sensing Regulator ExpR_Ecz in Modulation of Dickeya oryzae Motility and Virulence. [PDF]

Mol Plant Pathol
In the absence of OHHL synthase ExpIEcz, ExpREcz represses self‐expression via EDDR region and regulates Dickeya oryzae virulence traits. OHHL synthesised via ExpIEcz abolishes ExpREcz function but promotes OHHL production and D. oryzae virulence.

The MarR Family Transcriptional Regulator EmrR Negatively Regulates the Type III Secretion System (T3SS) and Positively Modulates Pathogenicity in Dickeya oryzae. [PDF]

Mol Plant Pathol
This study revealed that the transcriptional regulator EmrR in Dickeya oryzae modulates virulence by regulating hrpL expression and c‐di‐GMP levels. It affects motility, biofilm formation, cellulase production and pathogenicity. EMSA and footprinting confirmed EmrR binds directly to the promoter of its target operon.

Regulatory Mechanisms of Exoribonuclease PNPase and Regulatory Small RNA on T3SS of Dickeya dadantii

Molecular Plant-Microbe Interactions, 2010
The type III secretion system (T3SS) is an essential virulence factor for many bacterial pathogens. Polynucleotide phosphorylase (PNPase) is one of the major exoribonucleases in bacteria and plays important roles in mRNA degradation, tRNA processing, and
