additional information | construction of mutants, type II secretion system-deficient mutant of Dickeya dadantii 3937, A1919, DELTA ouC, loses the capability to promote the multiplication of EDL933, whereas Ech159, DELTApoS, a stress-responsive sigma-factor RpoS-deficient mutant, increases EDL933 proliferation on lettuce leaves 2fold mor than the wild-type strain. Mutant A1919 is completely deficient in the secretion of pectate lyases, which play a major role in plant tissue maceration | Dickeya dadantii |

malfunction | type II secretion system-deficient mutant of Dickeya dadantii 3937, A1919, DELTA ouC, loses the capability to promote the multiplication of EDL933, whereas Ech159, DELTApoS, a stress-responsive sigma-factor RpoS-deficient mutant, increases EDL933 proliferation on lettuce leaves 2fold mor than the wild-type strain. Mutant A1919 is completely deficient in the secretion of pectate lyases, which play a major role in plant tissue maceration | Dickeya dadantii |
additional information | RpoS, the general stress response sigma-factor involved in cell survival in suboptimal conditions, plays a role in EDL933 proliferation by controlling the production of pectate lyases in Dickeya dadantii 3937, e.g. via negative regulation of pelD promoter activity | Dickeya dadantii |
physiological function | the influence of the virulence mechanisms of Dickeya dadantii strain 3937, a broad-host-range phytopathogen, on the proliferation of the human pathogen Escherichia coli O157:H7 EDL933 on postharvest lettuce, strain 3937 promotes the multiplication of EDL933, overview | Dickeya dadantii |
