The whole transcriptome of the Antarctic copepod (Tigriopus kingsejongensis) was sequenced using Illumina RNA-seq. De novo assembly was performed with 64,785,098 raw reads using Trinity, which assembled into 81,653 contigs. TransDecoder found 38,250 candidate coding contigs which showed homology to other species by BLAST analysis. Functional gene annotation was performed by Gene Ontology (GO), InterProScan, and KEGG pathway analyses. Finally, we identified a number of expressed gene catalog for T. kingsejongensis that is a useful model animal for gene information-based polar research to uncover molecular mechanisms of environmental adaptation on harsh environments. In particular, we observed highly developing lipid metabolism in T. kingsejongensis directly compared to those of the Far East Pacific coast copepod Tigriopus japonicus at the transcriptome level.

Due to anthropogenic activities, coastal areas have been challenged with multi-stresses such as ocean warming and nickel (Ni) pollution. Currently, studies have concerned the combined effects of Ni and warming in marine organisms at the phenotypic level; however, the underlying molecular mechanisms are poorly known. In this study, a marine copepod Tigriopus japonicus was maintained under warming (+ 4℃) and an environmentally realistic level of Ni (20 μg/L) alone or combined for three generations (F0-F2).

Aged plastics possess diverse interactive properties with metals compared to pristine ones. However, the role of aging for nanoplastics (NPs) in being a carrier of mercury (Hg), a common marine environmental pollutant, and their combined effects remain unclear. This study investigated the carrier effect of ultraviolet-aged NPs on Hg and the ensuing toxicity in a marine copepod under a multigenerational scenario.

The present study focused, for the first time, on the adverse effects of nine REEs on the marine copepod For this purpose, copepod mortality, immobilization, and naupliar development were assessed. Overall, the results demonstrated that all REEs tested exerted significant adverse effects on , with LC50 values ranging from 0.56 to 1.
