Taxonomical, Physiological, and Biochemical Characteristics of DSTA20 from Hypersaline Environments of Taean Salt Pond, Republic of Korea.

, a halophilic unicellular chlorophyte, produces bioactive compounds and biofuels applicable to various industries. Despite its industrial significance, comprehensive studies on the morphological, physiological, and biochemical characteristics of the genus remain challenging. In this study, we characterized an axenically isolated green alga from a salt pond in Taean, Republic of Korea, and assessed its industrially relevant traits.

Comparative genomic analysis of copepod humoral immunity genes with sex-biased expression in Labidocera rotunda.

Studies of innate immune system function in invertebrates have contributed significantly to our understanding of the mammalian innate immune system. However, in-depth research on innate immunity in marine invertebrates remains sparse. We generated the first de novo genome and transcriptome sequences of copepod Labidocera rotunda using Illumina paired-end data and conducted a comparative genome analysis including five crustaceans (four copepods and one branchiopod species).

The complete mitochondrial genome of Mori, 1929 (Copepoda: Calanoida) from Jeju Island, Korea.

We sequenced the complete mitochondrial genome of the copepod (family Pontellidae) collected from Ihotaewoo Beach in Jeju, Korea. The mitochondrial genome was 16,564 bp in length and contained 13 protein-coding genes (PCGs), 22 transfer RNAs, and two ribosomal RNAs. The concatenated phylogenetic tree of was reconstructed using the maximum-likelihood method based on the eight PCGs obtained from eight species of copepods including .

Zooplankton diversity monitoring strategy for the urban coastal region using metabarcoding analysis.

Marine ecosystems in urban coastal areas are exposed to many risks due to human activity. Thus, long-term and continuous monitoring of zooplankton diversity is necessary. High-throughput DNA metabarcoding has gained recognition as an efficient and highly sensitive approach to accurately describing the species diversity of marine zooplankton assemblages.

Morphological and genetic differentiation of heteromorphy in Labidocera rotunda (Copepoda, Calanoida, Pontellidae).

The pontellid calanoid Labidocera rotunda Mori, 1929 is relatively widespread in the inshore surface waters of East Asia. In this study, some heteromorphic specimens have been observed with extreme morphological discrepancies in the female, including the genital double-somite, the second urosomite, the caudal rami, and the fifth leg. To evaluate the validity of species assignment of the morphological variants, we analyzed the DNA sequences of two mitochondrial genes, 16S rRNA and cytochrome oxidase subunit I (mtCOI).

Microstructure Analysis of Ti-xPt Alloys and the Effect of Pt Content on the Mechanical Properties and Corrosion Behavior of Ti Alloys.

The microstructure, mechanical properties, and corrosion behavior of binary Ti-xPt alloys containing 5, 10, 15 and 20 wt% Pt were investigated in order to develop new Ti-based dental materials possessing superior properties than those of commercially pure titanium (cp-Ti). All of the Ti-xPt (x = 5, 10, 15, 20) alloys showed hexagonal α-Ti structure with cubic Ti₃Pt intermetallic phase. The mechanical properties and corrosion behavior of Ti-xPt alloys were sensitive to the Pt content.

Reconstruction of arietellid copepod phylogenetic relationship, with description of a new species of Sarsarietellus (Copepoda, Calanoida, Arietellidae) from Korean waters.

A new species of the genus Sarsarietellus from Korean waters, S. orientalis n. sp.
