Transcription profiling analysis of the PecS regulon of Erwinia chrysanthemi 3937

ABSTRACT: Pathogenicity of the phytopathogenic enterobacterium Erwinia chrysanthemi, the causative agent of soft rot disease in many plants, is a complex process involving several factors whose production is subject to temporal regulation during infection. After penetrating into its host plant, E. chrysanthemi resides latently in the plant intercellular spaces without provoking any symptoms, and disease occurs only when the environmental conditions are favourable for massive bacterial multiplication and production of plant cell wall degrading enzymes. PecS is a transcriptional regulator of the MarR family that represses production of plant cell wall degrading enzymes. Here, we used microarray analysis to define the PecS regulon and demonstrated that PecS exerts wide-ranging effects on gene expressio
