Figure 5. Comparisons of the organization of the aio cluster and flanking sequence in 39 arsenite oxidizers genomes.

H. arsenicoxydans ULPAs1 is used as the reference genome. From outside to inside, first two rings donated ORF encoded from forward/reverse strand of the partial region of the H. arsenicoxydans ULPAs1 genome; rings 3 to 41 represent the 39 arsenite oxidizers at this order, which are shown under the cycle (from up to down and left to right).
