thermales thermales thermales is an order of bacteria belonging to the deinococcota phylum. they are particularly resistant to heat, and live in the benthic zone of the gulf of mexico. thermales scientific classification kingdom: bacteria phylum: deinococcota class: deinococci order: thermalesrainey and da costa 2002 family: thermaceaeda costa and rainey 2002 genera "allomeiothermus" calidithermus marinithermus meiothermus oceanithermus rhabdothermus thermus vulcanithermus members of the order thermales can be distinguished from all other bacteria through molecular signatures consisting of conserved signature indels (csis) and conserved signature proteins (csps) that are exclusively present in members of this order. specifically, six csis were identified in the following proteins: dna topoisomerase i, abc transporter permease, citrate synthase, phosphoribosylformylglycinamidine synthase, pyruvate dehydrogenase and alpha-glucan phosphorylase. 51 csps were also found to be exclusively shared by members of this order. in addition, a 76 aa csi is present in the protein seca preprotein translocase which is specific to all members of the order thermales as well as hydrogenibacillus schlegelii (also an thermophilic species). based on studies on other csis and csps, it is likely that some of these csis and csps could have implications in the thermophilic phenotype of thermales species. phylogeny 16s rrna based ltp_01_2022 120 marker proteins based gtdb 07-rs207 thermales thermaceae "allomeiothermus" jiao et al. 2022 calidithermus raposo et al. 2019 meiothermus nobre et al. 1996 rhabdothermus steinsbu et al. 2011 vulcanithermus miroshnichenko et al. 2003 oceanithermus miroshnichenko et al. 2003 marinithermus sako et al. 2003 thermus brock and freeze 1969 (approved lists 1980) deinococcales "marinithermaceae" marinithermus oceanithermus thermaceae "allomeiothermus" calidithermus meiothermus thermus trueperaceae deinococcaceae
