Comparison of arsenic-resistant genes identified in strain IITK SM2 with genes of other reference organisms: arsenic operon system in (a) strain IITK SM2, (b) other Citrobacter species, and (c) selected strains of Enterobacteriaceae a genus other than Citrobacter. The whole-genome sequence of each strain was considered for representing this schematic. Numbers appended after the name of some As-resistant genes indicate the difference in nucleotides. The gene bank or accession number of Citrobacter species used in this analysis is shown in Table S4 of the Supporting Information.
