Figure 2From: Comparative genomics reveals that a fish pathogenic bacterium Edwardsiella tarda has acquired the locus of enterocyte effacement (LEE) through horizontal gene transferPolymorphism of non-core genes among E. tarda strains. (A) Map of polymorphic genes that are either present or absent among the strains. The presence/absence of genes is shown in blue/yellow, respectively. (B) Phylogenetic tree of DNA gyrase subunit B genes (gyrB).Back to article page
