Genomic feature comparison of the selC -tRNA loci among a variety of STEC serotypes. Dashed lines (red and black color) represent the conserved gene regions. Sequence length between the black- and red-dashed lines (ranging from 7,775 to 49,562 bp) is indicated within the parenthesis. The ORFs are indicated by colors and numbers based on sequence similarity; arrow indicates the ORF orientation.
