“…This situation is similar to that in 'P. maritimus' [5]. Recent research revealed that members of the genus Psychroflexus may be particularly important for cheese ripening because genomes of these species contained putative cystathionine gamma-lyase, glutamate dehydrogenase, prolyl endopeptidase and aspartate aminotransferase genes [33].…”

“…In addition to the osmotic stress response mechanism, YR1-1 T contained eight genes for sulphur metabolism by KEGG ortholog-based potential metabolic pathways (Table S4), which can assimilate sulphate into sulfite, but the genes for dissimilatory or assimilatory nitrate reduction were not found. This situation is similar to that in ‘ P. maritimus ’ [5]. Recent research revealed that members of the genus Psychroflexus may be particularly important for cheese ripening because genomes of these species contained putative cystathionine gamma-lyase, glutamate dehydrogenase, prolyl endopeptidase and aspartate aminotransferase genes [33].…”

“…Members of this genus have been isolated from various saline environments, e.g. sea ice and hypersaline lakes [6], salt lake [7, 8], salt pan [9], marine solar saltern [2, 10], tidal flat [11], salted surface of a cheese [12] and coastal sediment [5]. The type species of this genus, Psychroflexus torquis , is considered a model sea-ice microorganism, which has adapted to an epiphytic lifestyle [13].…”

A Gram-stain-negative, strictly aerobic, non-motile, orange-coloured bacterium, designated YR1-1T, was isolated from a soil sample collected from the Yellow River Delta wetlands (PR China). Growth was observed at a salinity of 1.0–15.0 % NaCl, 4–45 °C and pH 6.0–9.0. The results of phylogenetic analysis based on the 16S rRNA gene sequences indicated that YR1-1T represented a member of the genus Psychroflexus , with the highest sequence similarity to Psychroflexus sediminis YIM-C238T (97.9 %), followed by Psychroflexus aestuariivivens (97.1 %) and Psychroflexus torquis (96.4 %). The average nucleotide identity and digital DNA–DNA hybridization values between YR1-1T and other closely related type strains of species of the genus Psychroflexus were 68.7–86.3% and 17.8–30.9 %. The genome of the strain was 2 899 374 bp in length with 39.8 % DNA G+C content. The predominant fatty acids (>10 %) were iso-C15 : 0 and anteiso-C15 : 0. The major respiratory quinone was menaquinone-6 (MK-6) and the major polar lipids were phosphatidylethanolamine, phospholipid, diphosphatidylglycerol, two unidentified aminolipids and four unidentified lipids. The combined genotypic and phenotypic data indicate that YR1-1T represents a novel species within the genus Psychroflexus , for which the name Psychroflexus aurantiacus sp. nov., is proposed. The type strain is YR1-1T (=KCTC 72794T=CGMCC 1.17458T).

The impact of epigenetic information on genome evolution

Epigenetic information affects gene function by interacting with chromatin, while not changing the DNA sequence itself. However, it has become apparent that the interactions between epigenetic information and chromatin can, in fact, indirectly lead to DNA mutations and ultimately influence genome evolution. This review evaluates the ways in which epigenetic information affects genome sequence and evolution. We discuss how DNA methylation has strong and pervasive effects on DNA sequence evolution in eukaryotic organisms. We also review how the physical interactions arising from the connections between histone proteins and DNA affect DNA mutation and repair. We then discuss how a variety of epigenetic mechanisms exert substantial effects on genome evolution by suppressing the movement of transposable elements. Finally, we examine how genome expansion through gene duplication is also partially controlled by epigenetic information. Overall, we conclude that epigenetic information has widespread indirect effects on DNA sequences in eukaryotes and represents a potent cause and constraint of genome evolution. This article is part of the theme issue ‘How does epigenetics influence the course of evolution?’

The proposed name contravenes Recommendation 6(3) of the ICNP. 8 Syllabification and etymology should be corrected as follows: Per. si. ci. mo'nas. L. masc. adj. persicus, of a peach; Gr. fem. n. monas, a unit, a monad; N.L. fem. n. Persicimonas, a peach-coloured monad. 9 Syllabification and etymology should be corrected as follows: Ra. oul. ti. bac'ter. N.L. masc. n. bacter, a rod; N.L. masc. n. Raoultibacter, a rod named in honour of the French microbiologist Didier Raoult, … In addition to the type species, the protologue designates a type strain of the genus, but a genus does not have a type strain. 10The effective publication states that the type strain was also deposited as LMG 27974, but no documentation was supplied. 11The heading of protologue must read: 'Description of Sphingobacterium bovistauri sp. nov.' instead of 'Description of Sphingobacterium Bovistauri sp. Nov.' 12The effective publication states that the type strain was also deposited as ICEBB-02, but no documentation was supplied. 13The effective publication states that the type strain was also deposited as UQM 41458, but no documentation was supplied.
