Diversity of polyamine patterns in soft rot pathogens and other plant-associated members of the Enterobacteriaceae.

Polyamine profiles of 91 pectolytic and other plant-associated strains from 30 taxa of the Enterobacteriaceae were obtained by gradient high performance liquid chromatography (HPLC). Pectobacterium carotovorum, basonym Erwinia carotovora, contained a high amount of putrescine and less diaminopropane. Diaminopropane was absent in Pectobacterium chrysanthemi, basonym E.
