“…However, IMCC14385 T together with H. japonicus S1-36 T and H. pacificus S1-72 T formed a paraphyletic clade with H. lutimaris HF004 T and H. sediminis U0301 T , indicating that H. lutimaris HF004 T and H. sediminis U0301 T may not belong to the genus Halioglobus. Since this phylogenetic relationship was also observed in a previous work [12], more robust phylogenetic analyses based on genome sequences were needed, which is described below.…”

“…Members of the genus Halioglobus have been found in diverse environments such as coastal sediment [21], salt marsh [22], coastal aquifer [23] and marine sponge [24] as well as seawater. As of October 2019, the genus comprises four species with validly published names, H. japonicus (type species of the genus) [10], H. pacificus [10], H. lutimaris [11] and H. sediminis [12], and is characterized by Gram-stain-negative, non-motile, NaCl-requiring, obligately aerobic and coccoid or rod-shaped bacteria that contain Q-8 as respiratory quinone and diphosphatidylglycerol and phosphatidylglycerol as major polar lipids. In this study, we isolated strain IMCC14385 T from surface seawater of the East Sea, Republic of Korea.…”

A Gram-stain-negative, rod-shaped, aerobic, non-flagellated, chemoheterotrophic bacterium, designated IMCC14385T, was isolated from surface seawater of the East Sea, Republic of Korea. The 16S rRNA gene sequence analysis indicated that IMCC14385T represented a member of the genus Halioglobus sharing 94.6–97.8 % similarities with species of the genus. Whole-genome sequencing of IMCC14385T revealed a genome size of 4.3 Mbp and DNA G+C content of 56.7 mol%. The genome of IMCC14385T shared an average nucleotide identity of 76.6 % and digital DNA–DNA hybridization value of 21.6 % with the genome of Halioglobus japonicus KCTC 23429T. The genome encoded the complete poly-β-hydroxybutyrate biosynthesis pathway. The strain contained summed feature 8 (C18 : 1 ω7c and/or C18 : 1 ω6c), summed feature 3 (C16 : 1 ω7c and/or C16 : 1 ω6c) and C17 : 1 ω8c as the predominant cellular fatty acids as well as ubiquinone-8 (Q-8) as the respiratory quinone. The polar lipids detected in the strain were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, five unidentified phospholipids, an unidentified aminolipid, an unidentified aminophospholipid and four unidentified lipids. On the basis of taxonomic data obtained in this study, it is suggested that IMCC14385T represents a novel species of the genus Halioglobus , for which the name Halioglobus maricola sp. nov. is proposed. The type strain is IMCC14385T (=KCTC 72520T=NBRC 114072T).

“…At the time of writing, the family Halieaceae contains eight genera, most of which are composed of one to three species with validly published names. Members of the family have been isolated from hypersaline mat [2], sea sand [8], seawater [3–5, 7, 9, 10] and sediments [6, 11–13]. During a study of bacterial isolates from tidal mudflats in coastal environments, a gammaproteobacterial strain, designated GH4-78 T , was recovered at Dongmak beach in the Republic of Korea.…”

Molecular evidence for origin, diversification and ancient gene duplication of plant subtilases (SBTs)

Plant subtilases (SBTs) are a widely distributed family of serine proteases which participates in plant developmental processes and immune responses. Although SBTs are divided into seven subgroups in plants, their origin and evolution, particularly in green algae remain elusive. Here, we present a comprehensive large-scale evolutionary analysis of all subtilases. The plant subtilases SBT1-5 were found to be monophyletic, nested within a larger radiation of bacteria suggesting that they originated from bacteria by a single horizontal gene transfer (HGT) event. A group of bacterial subtilases comprising representatives from four phyla was identified as a sister group to SBT1-5. The phylogenetic analyses, based on evaluation of novel streptophyte algal genomes, suggested that the recipient of the HGT of bacterial subtilases was the common ancestor of Coleochaetophyceae, Zygnematophyceae and embryophytes. Following the HGT, the subtilase gene duplicated in the common ancestor and the two genes diversified into SBT2 and SBT1, 3–5 respectively. Comparative structural analysis of homology-modeled SBT2 proteins also showed their conservation from bacteria to embryophytes. Our study provides the first molecular evidence about the evolution of plant subtilases via HGT followed by a first gene duplication in the common ancestor of Coleochaetophyceae, Zygnematophyceae, and embryophytes, and subsequent expansion in embryophytes.
