Figure 2. Phylogenetic analysis of the apsA gene clones.

Figure 2

The final dataset of 215 nucleotide sequences include sequences from low saline soil (SS1), high saline soil (SS2), agricultural soil (AS) clone libraries, coded as ‘PA’, ‘PB’ ‘PC’ respectively, and closely related apsA-gene sequences from known cultured representatives and environmental clones. 500 bootstrap analyses were performed and percentages are shown at nodes. The scale bar indicates 1.0 substitutions per site. The apsA gene sequence of Thermodesulfobacterium hveragerdense was used as outgroup for tree calculations.
