Linear representations of the RelNRNAI plasmids from our collection [8] and maximum-likelihood phylogenic trees of all the RelNRNAI plasmids, including those from the NCBI database (see the main text for details regarding their selection) reconstructed as described in the Methods section. (a) RelNRNAI plasmids of the type 1 family, (b) RelNRNAI plasmids of he type 2 family and (c) RelNRNAI plasmids of the type 3 family. Linear representation: replication systems (RNAI and rop gene) are grey, IS are pink, ESBL genes are red, other antibiotic resistance genes are green and other genes are white; a horizontal red line indicates genes of the backbones used for phylogenetic analysis. Phylogenetic tree: plasmid IDs are shaded in yellow for E. coli/Shigella sp., orange for S. enterica ssp. enterica, blue for K. pneumoniae and turquoise for other Enterobacteriaceae . ✹, plasmids from our collection. ‡, co-integrated in plasmids. Geographical origin, colicin operons, TA systems, RM systems, resistance genes and others genes are indicated at the right of the trees.
