Abstract

Bacteria of the genus Pseudomonas were isolated in axenic cultures from tubers with signs of soft rot in storage facilities of Kamchatka Krai and Kostroma Oblast. The isolated strains differed from each other and from the strains of pectolytic Pseudomonas isolated from potatoes by other authors in the sequences of the genes of 16S ribosomal RNA, DNA gyrase subunit B, and the sigma factor of DNA-dependent RNA polymerase. The strains caused pectolytic softening of potato tissue at temperatures of +10 °C and +25 °C, the affected area of potato tissue fluoresced when illuminated with ultraviolet light. At a temperature of +37 °C, the growth of the strains was inhibited.
