Alignment of mcr-1-carrying IncHI2 plasmids. Alignment was performed using BRIG30. pSLK172-1 (GenBank accession no. CP017632) was used as the reference due to the fact that it is the largest (369,298 bp) mcr-1-carrying IncHI2 plasmid and contains additional IncN and IncY replicons. GenBank accession no. of these plasmids are shown in Fig. 1.
