Abstract
Haloterrigena turkmenica (Zvyagintseva and Tarasov 1987) Ventosa et al. 1999, comb. nov. is the type species of the genus Haloterrigena in the euryarchaeal family Halobacteriaceae. It is of phylogenetic interest because of the yet unclear position of the genera Haloterrigena and Natrinema within the Halobacteriaceae, which created some taxonomic problems historically. H. turkmenica, was isolated from sulfate saline soil in Turkmenistan, is a relatively fast growing, chemoorganotrophic, carotenoid-containing, extreme halophile, requiring at least 2 M NaCl for growth. Here we describe the features of this organism, together with the complete genome sequence, and annotation. This is the first complete genome sequence of the genus Haloterrigena, but the eighth genome sequence from a member of the family Halobacteriaceae. The 5,440,782 bp genome (including six plasmids) with its 5,287 protein-coding and 63 RNA genes is part of the Genomic Encyclopedia of Bacteria and Archaea project.
Highlights
Strain 4kT (= DSM 5511 = ATCC 51198 = VKM B1734) is the type strain of the species Haloterrigena turkmenica, which is the type species of the genus Haloterrigena [1,2]
There are no reliable reports of other strains of H. turkmenica having been isolated. 16S rRNA sequence identity with the other seven type strains in the genus, which were mainly isolated from salt lakes, range from 98.0% for H. salina [7] to 94.4% for H. longa [6]
The presence of significant levels of both the diphytanyl moieties (C20, C20) and phytanyl-esterterpanyl moieties (C20, C25) is characteristic of all members examined of this evolutiohttp://standardsingenomics.org nary branch of the family Halobacteriaceae
Summary
There are no reliable reports of other strains of H. turkmenica having been isolated. 16S rRNA sequence identity with the other seven type strains in the genus, which were mainly isolated from salt lakes, range from 98.0% for H. salina [7] to 94.4% for H. longa [6]. We present a summary classification and a set of features for H. turkmenica strain 4kT, together with the description of the complete genome sequencing and annotation.
