Rhs loci in divergent S. alvi strains share similar sequences. Dark and light gray ribbons show regions of >95% and >90% nucleotide similarity between S. alvi strains wkB2 and App4-8, respectively. Nine sequences within App4-8 Rhs loci have high identity (>95%) to 7 of the 18 Rhs genes in wkB2. Sequences similar to a putative integrase in wkB2 (yellow) are present in many App4-8 contigs. CDS, coding sequences.
