Genetic structure of mcr-1 in two plasmids and structural comparison with related mcr-1-carrying IncX4 plasmids. Regions with > 99% identity are shaded in gray. Red arrow indicates resistance genes. Purple arrow represents conjugal transfer genes. Green arrow represents plasmid replication genes. Blue arrow represents genes for maintenance and stability. Black arrow indicates other genes. The delta symbol (Δ) indicates a truncated gene or mobile element. Direct repeats are indicated by arrows and sequences
