Members of this genus infect Pectobacterium carotovorum subsp. carotovorum. The first isolate to be described was Pectobacterium phage PM1. No terminal repeats have been reported for suwonvirus genomes. On average the genome of viruses belonging to this genus are 54.22 kbp (44.9 % G+C) and encode 71 proteins and 0–1 tRNAs.
Species demarcation criteria
Members of the same species are more than 95% identical in genome nucleotide sequence, including the terminal repeat region. Viruses with genomes that differ by more than 5% are assigned to different species.
