  1. aBased on pangenome analysis of 21 isolates using Roary (Additional file 9). Genes in a putative bacteriocin synthesis gene cluster are highlighted in italics.
  2. bThe presence or absence of the genes was investigated by TBLASTN using the gene products of DAT741 (coverage, > 80%; amino acid identities, > 80%).
