Fig. 5: Correlation between T4SS types, plasmid replication types, bacterial hosts, and mcr genotypes.

The Sankey diagram illustrates the corresponding relationships in the following order: plasmid replicon types to T4SS gene clusters, T4SS gene clusters to host bacteria, and host bacteria to the carried mcr gene types. Due to space limitations, the names of the 58 replicon types are labeled alongside the image. “Unknown type” means: no known plasmid replicon type was identified. “No T4SS” means: no known T4SS gene cluster was identified. The number of plasmids in each group is shown in parentheses. The data are provided in the Supplementary Data 1 (https://doi.org/10.5281/zenodo.14861845).
