FIG. 1.

TCS-generated haplotype network and nested clades for Mediterranean vibrios and Photobacterium leiognathi symbionts. Each line represents one base pair difference, with black circles representing an unsampled intermediate haplotype. Each numbered circle represents a distinct haplotype, with color denoting collection site. The size of each circle is proportional to the number of individuals representing each given haplotype. Nested clades are marked by two-number identifiers within each box, signifying the representative nested clade.
