From: Genetic Analysis of the IncX4 Plasmids: Implications for a Unique Pattern in the mcr-1 Acquisition
Phylogenetic tree and linear comparison of the 21 IncX4 plasmids. A total of 29 plasmids were collected by July 18, 2016, but only one was chosed for analysis in the highly similar plasmids. These plasmids included 3 found in this study and 18 downloaded from the GenBank (Table S1). (a) The trees are generated using MEGA (version 6) based on the complete sequence of IncX4 plasmids. (b) Boxed arrows represent the position and transcriptional direction of ORFs. Regions of >99% identity are marked by grey shading. Genes associated with the tra and pil loci are colored light blue, replication associated genes are colored dark blue, antibiotic resistance genes are colored red, insertion sequences are colored green, and other genes are colored gray. The Variable Region I, II, and III, as well as the primers used were marked.
