Figure 1From: Insights into the evolution of sorbitol metabolism: phylogenetic analysis of SDR196C familyPhylogenetic tree of all species encoding SDH gene. The tree was obtained using Neighbor Joining (NJ) analysis in MEGA 4.0 [45]. 1,000 generations were used to build the consensus tree, as indicated in the methods section. The main inclusive taxonomic groups are indicated. The bacteria used are listed in Additional file 1.Back to article page
