The Histone Acetyltransferase Involved in the Regulation of Abiotic Stress Responses and Astaxanthin Accumulation in .

The histone acetyltransferases (HATs), together with histone deacetylases, regulate the gene transcription related to various biological processes, including stress responses in eukaryotes. This study found a member of HATs () from a transcriptome of the economically important microalgae . Its expression pattern responding to multiple abiotic stresses and its correlation with transcription factors and genes involved in triacylglycerols and astaxanthin biosynthesis under stress conditions were evaluated, aiming to discover its potential biological function.

Characterization of the mitochondrial genome of (perciformes, mullidae).

, a species in the family Mullidae, inhabits the coastal and inner lagoon reefs of the Indian and Pacific oceans. The mitochondrial genome of is 16,566 base pairs in length and contains 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes, and a D-loop control region. The overall base composition is 26.

Complete mitogenomes of four species: A taxonomic review of the species complex.

Four species, , , , and , from the coasts of the China Seas, have been identified and their entire mitochondrial genomes (mitogenomes) have been sequenced by next-generation sequencing technology. A comparative analysis of five mitogenomes was conducted, including the mitogenome of . The mitogenomes contained 16.

Toxic Characteristics and Action Mode of the Mixotrophic Dinoflagellate on Co-Occurring Phytoplankton and Zooplankton.

The mixotrophic dinoflagellate frequently forms harmful algal blooms around the world and has caused massive deaths of shellfish, finfish and birds, yet its toxic mechanism is still unclear. In this study, toxic effects of on co-culturing phytoplankton and zooplankton were investigated. The results showed that sonicated cultures of JX13 and JX14, isolated from the Pearl River Estuary, had a significant lethal effect on the rotifer , with the highest mortality rate of 80%.

Accumulated Lipid and Astaxanthin in a Moderate and Sustainable Way by the Self-Protection Mechanism of Salicylic Acid Under Sodium Acetate Stress.

To elucidate the mechanism underlying increased fatty acid and astaxanthin accumulation in , transcriptome analysis was performed to gain insights into the multiple defensive systems elicited by salicylic acid combined with sodium acetate (SAHS) stresses with a time course. Totally, 112,886 unigenes and 61,323 non-repeat genes were identified, and genes involved in carbon metabolism, primary and secondary metabolism, and immune system responses were identified. The results revealed that SA and NaAC provide both energy and precursors to improve cell growth of and enhance carbon assimilation, astaxanthin, and fatty acids production in this microalga with an effective mechanism.

Changes in the trophic niche of in the Beibu Gulf in different periods.

We measured stable carbon and nitrogen isotopes and calculated trophic level and trophic niche of , with samples collected from the Beibu Gulf from 2008 to 2009 and 2018. The differences between two periods were compared and analyzed to explore the changes of its ecological adaptation. The results showed that value of δC varied substantially between the two periods.

Characterization of the mitochondrial genome of (Perciformes, Gobiidae).

, belongs to the family Gobiidae, which is widely distributed in estuarine and marine waters of the coasts of the Indian and the western Pacific Oceans. The entire mitochondrial genome of is 16,415 base pairs (bp) in length and contained 13 protein-coding genes (PCGs), 2 ribosomal RNA (rRNA) genes, and 22 transfer RNA (tRNA) genes. The overall base composition is 27.

Characterization of the complete mitochondrial genome of the coral reef fish, (Pisces: Labridae) and its phylogenetic implications.

belongs to the family Labridae, which inhabit in coastal and continental shelf waters. The entire mitochondrial genome of is 16,527 base pairs (bp) in length and contained 13 protein-coding genes, two rRNA genes, and 22 tRNA genes. The overall base composition is 27.
