Soft rot Pectobacteria (SRP) that cause soft rot and black leg of potato and vegetable crops are worldwide-spread phytopathogens posing serious economic threat to agriculture and food industry. We studied phylogenetic relations within genera Pectobacterium and Dickeya applying complete-genome comparisons of previously sequenced and obtained de novo genomes of the members of these genera. Phylogenetic studies with several different sets of conservative genes were done by several algorithms. Unique taxon-specific regions were found in the investigated genomes. We traced the relationships between species and detected several examples of lateral gene lateral transfer including conservative (core) genes exchange.
