    ..Whereas homologs of Ecc71 aepA occur in E. c. subsp. carotovora and E. c. subsp. atroseptica strains, activation of exoenzyme production is markedly stimulated by aepA in E. c. subsp. carotovora than in E. c. subsp. atroseptica. ..

    ..Our findings support the idea that KdgREcc affects transcription by promoter occlusion, i.e., preventing the initiation of transcription, and by a roadblock mechanism, i.e., by affecting the elongation of transcription. ..

    ..herbicola pv. gypsophilae and support the hypothesis that the effects of this two-component system on extracellular protein production in E. carotovora subsp. carotovora is mediated, at least in part, via the levels of rsmB transcripts. ..
