Co-occurrence of latent Dickeya and Pectobacterium species in potato seed tuber samples from northern Finland

Recent methodological developments have uncovered the etiological diversity of potato blackleg and soft rot Pectobacteriaceae. At least five species in genera Dickeya Pectobacterium been confirmed to cause on potatoes Finland. The bacteria are seed borne remain latent tuber until conditions favourable for growth, multiplication infection prevail. Tubers could be infected by one or more these species. This short communication is based results molecular detection data collected than 14 years from lots produced Diagnostic PCR assay specific solani, atrosepticum, carotovorum, P. brasiliense parmentieri revealed that species; it also single common multiple colonization. An event simultaneous occurrences different strains appears frequent observed between absence co-occurrence solani atrosepticum intriguing.
