Figure F1. Phylogenetic tree (maximum likelihood distance) of marine subsurface archaea and related phylotypes, based on ~900 positions of the 16S rRNA gene, based on PCR amplicons obtained with primers 8F and 915R (Sørensen et al., 2004). For each archaeal lineage discussed in this review and listed in Table T1, representative published sequences were obtained from GenBank (Benson et al., 2005). When available, sequences from Sites 1225 and 1231 were used for tree inference. The source habitats of 16S rRNA sequences are color-coded as shown.
