Giant viruses are remarkable for their large genomes, often rivaling those of small bacteria, and for having genes thought exclusive to cellular life. Most isolated to date infect nonmarine protists, leaving their strategies and prevalence in marine environments largely unknown. Using eukaryotic single-cell metagenomics in the Pacific, we discovered a Mimiviridae lineage of giant viruses, which infects choanoflagellates, widespread protistan predators related to metazoans. The ChoanoVirus genome...

The fisheries resources of the Yangtze Estuary and its adjacent waters have undergone dramatic declines as a consequence of environmental changes and human activities, with traditional ecological investigations demonstrating progressive decreases in species diversity and annual numbers in the fisheries resource. Environmental DNA (eDNA) technology has been demonstrated as an effective tool by many studies for detecting fish species, monitoring fish biodiversity and indicate the fish abundance. I...

INTRODUCTION Perceptual experiences in mammals may arise from patterns of neural circuit activity in cerebral cortex. For example, primary visual cortex (V1) is causally capable of initiating visual perception; in human neurosurgery patients, V1 electrical microstimulation has been reported to elicit basic visual percepts including spots of light, patterns, shapes, motions, and colors. Related phenomena have been studied in laboratory animals using similar electrical stimulation procedures, alth...

Many microorganisms express rhodopsins, pigmented membrane proteins capable of absorbing sunlight and harnessing that energy for important biological functions such as ATP synthesis and phototaxis. Microbial rhodopsins that have been discovered to date are categorized as type-1 rhodopsins. Interestingly, researchers have very recently unveiled a new microbial rhodopsin family named the heliorhodopsins, which are phylogenetically distant from type-1 rhodopsins. Among them, only heliorhodopsin-48C...

Although culture-independent studies have shown the presence of Verrucomicrobia in the deep sea, verrucomicrobial strains from deep-sea environments have been rarely cultured and characterized. Recently, Rubritalea profundi SAORIC-165T, a psychrophilic bacterium of the phylum Verrucomicrobia, was isolated from a depth of 2,000 m in the northwestern Pacific Ocean. In this study, the genome sequence of R. profundi SAORIC-165T, the first deep-sea verrucomicrobial isolate, is reported with descripti...

The taxonomy of marine and non-marine organisms rarely overlap, but the mechanisms underlying this distinction are often unknown. Here, we predicted three major ocean-to-land transitions in the evo ...

AbstractTwo complete and one near-complete mitochondrial genomes (mitogenomes) were determined for a deep-sea holothurian species of the genus Scotoplanes (Elpidiidae). Each sequence contains two ribosomal RNA genes, 22 transfer RNA genes, and 13 protein-coding genes, as found in most previously determined holothurian mitogenomes. The protein-coding genes use ATG or ATA as the start codon, and TAA or TAG as the stop codon. Phylogenetic reconstruction using the maximum likelihood method confirmed...

A novel Gram-negative bacterium, designated 4G11T, was isolated from the sea surface microlayer of a marine inlet. On the basis of 16S rRNA gene sequence analysis, the strain showed the closest similarity to Amylibacter ulvae KCTC 32465T (99.0 %). However, DNA–DNA hybridization values showed low DNA relatedness between strain 4G11T and its close phylogenetic neighbours, Amylibacter marinus NBRC 110140T (8.0±0.4 %) and Amylibacter ulvae KCTC 32465T (52.9±0.9 %). Strain 4G11T had C18 : 1, C16 : 0 ...

AbstractThe complete mitochondrial genome (mitogenome) was determined for the longfin dragonfish Tactostoma macropus, which is the first for the genus and the third within the family Stomiidae. The mitogenome sequence is 17,690 bp in length containing 2 ribosomal RNA genes, 22 transfer RNA genes, 13 protein-coding genes, and a control region, as in most fishes. The gene order of T. macropus showed an unreported deviation from the typical vertebrate one. Phylogenetic reconstruction using the maxi...

ABSTRACT Here, we report the draft genome sequence of Saccharospirillum sp. strain MSK14-1, isolated from surface seawater collected at Aburatsubo Inlet in Japan. The genome sequence of strain MSK14-1 should contribute to our understanding of the characteristics of the genus Saccharospirillum.
