Figure 1. Phylogenetic analysis of the cbbM gene clones.

Figure 1

The final dataset of 168 nucleotide sequences include sequences from low saline (SS1), high saline (SS2), agricultural (AS) and rhizosphere (RS) soil clone libraries, coded as ‘CA’, ‘CB’, ‘CC’, and ‘CD’ respectively, and closely related cbbM gene sequences from known cultured representatives and environmental clones. The scale bar indicates 0.5 substitutions per site. The cbbM gene sequence of Methanohalophilus mahii was used as outgroup for tree calculations.
