Figure 1

Comparison of mobile genetic elements identified in this study and those previously described. Elements are named as in text, and isolates in which these elements were identified are named in parentheses. Predicted genes are depicted by horizontal arrows; cyan arrows represent tet(M) resistance genes, the orange arrow indicates cat, and purple arrows represent lantibiotic-associated genes. Red bars represent BLASTn matches between sequences. Blue bars represent reverse-oriented BLASTn matches. The region of missing sequence within the Tn916-(bacterio)phage composite element is indicated by a vertical black arrow; the asterisk marks an ~11.3 kb insertion in ICESp PN1 (as described in Results). See Additional file 1 for details about the genes found within the Tn916-phage composite and ICESp PN1 elements.
