FIGURE 10.

Schematic presentation of the structure of genomic islands belonging to the three groups. The schematic structure is presented for the three groups of genomic islands: (A) Group 1 resistance islands equipping the tyrosine-based integrase gene at the 5’ terminal and the conjugative transfer machinery gene cluster at the 3’ terminus, (B) Group 2 resistance islands carrying a transposition module of a whole or a partial TniABQR component, (C) and the others. The genes are indicated with open arrows and colored based on function: genes for integration and recombination of the genomic island are in yellow, genes for antimicrobial resistance (AMR) are in red, genes for heavy metal resistance (HMR) are in green, the intI1 gene is in orange, conjugative transfer module mostly composed of the type 4 pili assembly genes is in black, and the core gene is in gray. The open box indicates inverted repeats (IRs) left and right, named the attL and attR loci for integration conjugative elements.
