Temperature is considered to be a major abiotic factor influencing aquatic life. Marine heatwaves are emerging as threats sustainable shellfish aquaculture, affecting the farming of New Zealand's green-lipped mussel [Perna canaliculus (Gmelin, 1791)]. In this study, P. were gradually exposed high-temperature stress, mimicking five-day marine heatwave event, better understand effects heat stress on metabolome mussels. Following liquid chromatography-tandem mass spectrometry analyses haemolymph samples, key sugar-based metabolites supported energy production via glycolysis pathway and TCA cycle by 24 h 48 stress. Anaerobic metabolism also fulfilled role production. Antioxidant molecules acted within thermally stressed mussels mitigate oxidative Purine tissue protection replenishment. Pyrimidine nucleic acids protein synthesis. Amino ensured balanced intracellular osmolality at ammonia detoxification h. Altogether, work provides evidence that has potential adapt up °C regulating its metabolism, balancing nucleotide production, implementing mechanisms over time. The data reported herein can used evaluate risks improve mitigation strategies for aquaculture.

Changes in the types and contents of metabolites plants can occur response to environmental stress. In this study, pumpkin seeds were cultivated a cadmium ion solution (cadmium sulfate) for 7 days, growth parameters, antioxidant enzyme activities, root, stem, leaf analyzed. The results showed that accumulation characteristics order root > stem leaf. Cadmium restrained promoted superoxide dismutase, peroxidase, catalase activities but inhibited their did not change total biomass seedlings. Orthogonal partial least squares (OPLS) analyses conducted detect relationships between fresh weight metabolites. These revealed maltose had significantly positive with influenced glyoxylate dicarboxylate metabolism, aminoacyl-tRNA biosynthesis, sulfur butanoate alanine, aspartate glutamate glutathione glycine, serine threonine metabolism root; glycolysis/gluconeogenesis stem; biosynthesis unsaturated fatty acids, galactose cutin, suberine wax It is important by inhibiting carbohydrate transport from carbohydrates Furthermore, also amino acid provide new information about how seedlings respond

Understanding the genetic basis of trait variations and their coordination between relative species or populations distributing in different environmental conditions is important evolutionary biology. In marine ectotherms, growth-defense trade-offs are a common ecological phenomenon. However, biochemical molecular mechanisms that govern these ectotherms perspective remain poorly investigated. Oysters among most global aquaculture. Crassostrea gigas ( C. ) angulata two allopatric congeneric dominant oyster inhabit northern southern intertidal areas China. Wild were spawned, F 1 progeny cultured same sites to reduce effects. Untargeted metabolomics transcriptomics, together with phenotypic parameters including morphological traits (growth performance), nutritional content (glycogen, crude fat, fatty acid content), physiology (normalized oxygen consumption rate total antioxidant capacity) applied assess metabolic transcript divergences . Integrated analyses metabolites transcriptomes showed allocated more energy storage defense by suppressing glycolysis, oxidation upregulating synthesis, gene expression, related metabolites. The results further confirmed data has higher glycogen fat unsaturation stronger capacity than contrast, exhibited better growth performance rate. These findings suggest allocates growth, which embodied its aerobic levels protein synthesis genes, metabolites, growth-related biomarkers. This study will help enlighten patterns underlying allocation. Also, key genes acids pathway identified this be for meat quality improvement industry.

Global warming is predicted to increase prolonged thermal challenges for aquatic ectotherms, i.e. it causes metabolic performance declines, impacts food intake, and finally impaired growth. In this research work, we investigated whether a tropical fish, Danio rerio (zebrafish), could tolerate the temperature has significant impact on growth metabolism. To answer our questions, evaluate metabolomic performance, question that received little attention so far, using differential chemical isotope labeling (CIL) liquid chromatography-mass spectrometry (LC-MS). Three groups of fish were exposed various temperatures 27.6 ± 2°C, 30.7 2°C or 32.2 during 270 days post fecundation (dpf) performance. The results obtained demonstrated different changes in response acclimation temperatures. After days, maintained at highest tested (32°C) showed reduced growth, condition factor, elevated levels metabolites associated with amino acid catabolism lipid metabolism pathways liver intestine compared kept lower (27.6 2°C). These findings demonstrate an explicit redistribution energy stores protein temperature, thus showing preference maintaining length limited availability. Moreover, here also screened out both marker altered provide essential insights ascertain effects water development fish.

The tiger puffer ( Takifugu rubripes ) is an important economic fish species in northern China. However, it a warm-temperature species, and low winter temperatures can result high mortality aquaculture. Understanding the mechanisms of cold resistance puffers will thus provide critical information to help cope with cold. In this study, we performed transcriptome analysis livers from kept at different (18°C, 13°C, 8°C) identify key pathways genes involved response low-temperature stress. We also detected serum levels proteases, arginine, proline obtain further on adaption. Totals 51, 942, 195 differentially expressed were identified 18°C vs 8°C, 13°C 8°C groups, respectively. Pathway showed that significantly enriched mainly related digestion, metabolism, environmental adaptation. Most digestion metabolism down-regulated, while most adaptation up-regulated. Serum proteases lower groups (13°C compared control group (18°C), arginine higher other two groups. These results suggest temperature caused digestive metabolic disorders, as well adaptive changes puffers.
