Figure 4From: Genes involved in arsenic transformation and resistance associated with different levels of arsenic-contaminated soilsPhylogenetic evidence of potential HGT of arsB / ACR3(2). Phylogenetic comparison between 16S rRNA genes (A) and potential horizontally transferred arsB/ACR3(2) genes (B). All sequences used in A's and B's construction are subsets of Fig. 1 and Fig. 3 respectively.Back to article page
