Figure 1.

Phylogenetic position of the proposed genus ‘Halanaeroarchaeum' within the family Halobacteriaceae. Complete haloarchaeal genome sequences available in 2014 are denoted by red circles, scaffolds by green squares and contigs by blue triangles. Haloarchaeal genera known only by 16S rRNA gene sequences are shown in grey. For the genera included in the Group I and Group II, see Supplementary Table S1. Insert: The detailed phylogenetic tree of ‘Halanaeroarchaeum'-related sequences from SILVA database and those produced in this study. Similar clones are indicated in parentheses. Support for nodes in this tree corresponds to bootstrap values for 1000 pseudo-replicates. Only bootstrap values at nodes greater than 75% are displayed as solid circles. The tree has been arbitrarily rooted with the closest sequences from haloarchaea of the Salt Deposit Clade II (SD-II) (7). Sequence of Natronomonas pharaonis (D87971) was used for outgrouping. Sequences from cultured organisms are denoted in red.
