Figure 2 Genetic organization of scaffolds containing mcr-3.6 obtained from Aeromonas veronii strain w55 in this study, and structural comparison with A. allosaccharophila IMT43045 (GenBank accession no. MF598076.1). The positions and orientations of the genes are indicated by arrows, with the direction of transcription shown by the arrowhead. Grey shading indicates >99% nucleotide sequence identity. The genetic structure of transposon Tn6518 is shown in circular form.
