Global Regulators ExpA (GacA) and KdgR Modulate Extracellular Enzyme Gene Expression Through the RsmA-rsmB System in Erwinia carotovora subsp. carotovora
The production of the main virulence determinants, the extracellular plant cell earthbath facial wipes wall-degrading enzymes, and hence virulence of Erwinia carotovora subsp.carotovora is controlled by a complex regulatory network.One of the global regulators, the response regulator ExpA, a GacA homolog, is required for transcriptional activation
