Dissimilar gene repertoires of Dickeya solani involved in the colonization of lesions and roots of Solanum tuberosum.

ABSTRACT: Dickeya and Pectobacterium species are necrotrophic pathogens that macerate stems (blackleg disease) and tubers (soft rot disease) of Solanum tuberosum. They proliferate by exploiting plant cell remains. They also colonize roots, even if no symptoms are observed. The genes involved in pre-symptomatic root colonization are poorly understood. Here, transposon-sequencing (Tn-seq) analysis of Dickeya solani living in macerated tissues revealed 126 genes important for competitive colonization of tuber lesions and 207 for stem lesions, including 96 genes common to both conditions. Common genes included acr genes involved in the detoxification of plant defense phytoalexins and kduD, kduI, eda (=kdgA), gudD, garK, garL, and garR genes
