Figure 4.
Phylogenetic tree of 142 bacterial clone sequences. (A) Proteobacteria from Gotjawal soils (80 clone sequences), with reference sequences. Twelve previously unknown clades are indicated as novel genera within the phylum. (B) Acidobacteria (13 clone sequences), with reference sequences. (C) Actinobacteria (28 clone sequences). (D) Chloroflexi, Bacilli, Cyanobacteria, and Planctomycetes (10 clone sequences). Bold letters refer to clone sequences. Each clade that appears to be a previously discovered taxon, based on the 16S rRNA divergence from the nearest previously known relative, is indicated.
