Schematic map made using XPlas, Map DNA for Mac OS XAp (http://www.iayork.com) showing the annotated xylose utilization operon from MOD1_AS-15 C. sakazakii strain (a). Xylose utilization operon for C. sakazakii strains MOD1_Jor22, _Jor151, AS-15,_ KW3 which were extracted from PairWise Alignments using Geneious (https://www.geneious.com/) showing the identical sequence repeat regions which are associated with each gene of the operon and captured using the identical repeat sequence region function in Geneious (b). Repeat regions are denoted by bronzed colored lines below each operon gene. These repeated regions are also shown in Additional file 5: Table S5. c Nucleotide sequence alignment captured in Geneious for repeat region five in xylB for MOD1_AS-15 and MOD-1_Jor22 showing the presence of the repeat region in MOD1_Jor22 (56,266 to 56,280, see red box). Note that bax can contain two to three identical repeat regions which suggest that this is an important highly regulated gene. bax has been shown to induce cell apoptosis of Arabidopsis protoplast cells through reactive oxygen independent and dependent processes namely DNA fragmentation, increased vacuolation, and loss of plasma membrane integrity [61]
