The role of genomic islands in virulence of Pectobacterium carotovorum subspecies brasiliensis on potatoes
… several strains have been shown to cause blackleg of potato stems. In contrast, P. atrosepticum is best known as a seedborne pathogen that causes blackleg. It is also responsible for soft rotting of tubers. Given the taxonomic distance between these two species and that only some strains …

The Histology and Histochemistry of The Wound-Healing Process in Geranium Cuttings in Relationship to Basal Stem Rot Caused by Pythium Ultimum
… beginning to emerge) or fully rooted cuttings. Blackleg, caused by Pythium species, is a problem in geranium propagation. Cuttings of Pelargonium hortorum 'Yours Truly' were inoculated with an isolate of Pythium ultimum. Extensive basal stem rot occurred on all freshly broken cuttings. A …

Genes and mechanisms in Arabidopsis innate immunity against Leptosphaeria maculans
… is a hemibiotrophic ascomycete that causes blackleg disease on Brassica oilcrops, which globally is a great threat for oilseed production. In order to obtain mechanistic understanding of this devastating pathogen, Arabidopsis thaliana was used as a model host. Susceptible genotypes of …

Identification of novel regulators of the necrosis-inducing protein (Nip) and carbapenem antibiotic production in the phytopathogen Pectobacterium
… phytopathogen that causes soft rot and blackleg disease of potatoes. It produces plant cell wall degrading enzymes (PCWDEs) and is capable of swimming and swarming motility. Some strains also produce a simple β-lactam carbapenem antibiotic, 1-carbapen-2-em-3-carboxylic acid. This …

Evolution of a gene for pathogenicity: endo-pectate lyase
… cause soft rot disease of many plant species and blackleg disease of potatoes, respectively. Ecc and Eca attack plants by means of a group of extracellular plant tissue-degrading enzymes. which rapidly breaks down the pectic polymers that form a structurally important part of the plant cell wall, …

Soft rot Enterobacteriaceae-molecular detection and biocontrol under in vitro and in vivo conditions
… is not the major pathogen causing soft rot or blackleg in Northern Ireland. The most dominant species were Pectobacterium atrosepticum and Pectobacterium carotovorum subsp. carotovorum. Pectobacterium atrosepticum was also detected on hosts other than potato. Testing of bacteria isolated from …
