Phylogenetic tree of arsenical pump membrane protein genes (arsB, acr3P) obtained from arsenite resistant isolates from soil samples. The tree was calculated from deduced amino acid sequences aligned in program ClaustalX and was generated in program MEGA 5 using the neighbour-joining algorithm. Bootstrap value (n = 1000 replicates)
