FIG 1.

L. monocytogenes possesses promiscuous and clade-specific methyltransferase specificities. (A) An L. monocytogenes phylogenetic tree was constructed based on genome distances and displays overall clustering by lineage. Additional metadata for all strains are provided in Table S1 in the supplemental material. (B) L. monocytogenes clade representing multiple methyltransferase specificities. (C and D) Lineage II-specific motif (GANNNNNNTGCG) (C) and promiscuous motif (GATC) (D) that is associated with a single clade independent of geographical location and time of isolation.
