Schematic representation of the distribution of specific mutations in F. psychrophilum phage-resistant isolates. Genes are represented as arrows, and deletion mutations are represented by short lines. Functions for genes are shown in colored boxes. Specific region of 50 kbp presented deletions in several proteins (accession numbers according to the position: WP_011964238.1, WP_011964239.1, WP_011964240.1, WP_011964241.1, WP_011964251.1, WP_011964252.1, WP_011964253.1, WP_011964254.1, WP_011964255.1, WP_016361990.1, WP_011964257.1, WP_011964258.1, WP_011964259.1, WP_011964260.1, and WP_011964261.1).
