Figure 2From: Phylogenetic analysis of bacterial and archaeal arsC gene sequences suggests an ancient, common origin for arsenate reductaseEvolutionary distance tree based on arsC gene sequences. The tree was constructed by neighbor joining methods using 408 informative positions. Numbers represent percentages of 1000 bootstraps and are only shown for bootstrap values <80%. Plasmid-borne arsC genes are indicated by "plasmid" following the organism name. Names in boxes represent branches that are inconsistent with the 16S rRNA tree.Back to article page
