Figure 1.

Phylogenetic tree highlighting the position of T. aggregans relative to the other type strains of the other genera within the family Desulfurococcaceae. The tree was inferred from 1,307 aligned characters [8,9] of the 16S rRNA gene sequence under the maximum likelihood criterion [10] and rooted in accordance with the current taxonomy. The branches are scaled in terms of the expected number of substitutions per site. Numbers above branches are support values from 200 bootstrap replicates [11] if larger than 60%. Lineages with type strain genome sequencing projects registered in GOLD [12] are shown in blue, published genomes in bold.
