Also, both strains are extremely resistant to gamma irradiation, with 60% survival rate after exposure to 5.0 kGy [1]. They share this radiation resistance trait with strains from the genus Deinococcus, Kineococcus radiotolerans and the actinobacterial 17-AAG HSP genus Rubrobacter [25]. Figure 2 Scanning electron micrograph of T. radiovictrix RQ-24T Table 1 Classification and general features of T. radiovictrix RQ-24T according to the MIGS recommendations [16]. Chemotaxonomy All attempts to identify a peptidoglycan of strain RQ-24T failed [1]. The polar lipids comprised as complex mixture of glycolipids and phospholipids, although no attempt has been made to compare them with the characteristic compounds found in members of the orders Deinococcales or Thermales. The major respiratory quinone is menaquinone 8 (MK-8).

The fatty acids are predominantly saturated branched acids of which anteiso-C15:0 (38.6%), anteiso-C17 (17.2%) and iso-C17:0 (16.6%) as well as iso-C16:0 (6.9%). One acyl compound has an equivalent chain length (ECL) consistent with iso-C18:0 1,2-diol and another compound with ECL 16.090 probably representing iso-C15:0 diol. The presence of the long-chain 1,2 diols is unknown in members of the genus Deinococcus (although the methods normally used would not identify them), while they are found in some other members of the genera Thermus and Meiothermus. Despite the fact that members of the species T. radiovictrix is described as being red pigmented there is no data on the nature of the pigments.

Genome sequencing and annotation Genome project history This organism was selected for sequencing on the basis of its phylogenetic position [26], and is part of the Genomic Encyclopedia of Bacteria and Archaea project [27]. The genome project is deposited in the Genomes OnLine Database [7] and the complete genome sequence is deposited in GenBank. Sequencing, finishing and annotation were performed by the DOE Joint Genome Institute (JGI). A summary of the project information is shown in Table 2. Table 2 Genome sequencing project information Growth conditions and DNA isolation T. radiovictrix RQ-24T, DSM 17093, was grown in DSMZ medium 1033 (Thermus Medium) [28] at 50��C. DNA was isolated from 0.5-1 g of cell paste using MasterPure Gram-positive DNA purification kit (Epicentre MGP04100) following the standard protocol as recommended by the manufacturer, with modification st/LALM for cell lysis as described in Wu et al.

[27]. DNA of strain RQ-24T is available Brefeldin_A through the DNA Bank Network [29,30]. Genome sequencing and assembly The genome was sequenced using a combination of Illumina and 454 sequencing platforms. All general aspects of library construction and sequencing can be found at the JGI website [31]. Pyrosequencing reads were assembled using the Newbler assembler version 2.1-PreRelease-4-28-2009-gcc-3.4.6-threads (Roche).
