Abstract
Low temperature in winter poses a threat to the Manila clam Ruditapes philippinarum in North China. However, a number of low-temperature-tolerant clams could survive such condition. It is therefore of interest to explore the survival mechanisms underlying the cold tolerance of R. philippinarum. The Zebra II population of R. philippinarum (Zebra II) from North China and the native Putian population from South China were used as experimental materials. Both populations were stressed with low-temperature and the differences in their survival rates, energy metabolism and transcriptional responses were compared. The results shown that after cold treatment at -1.9 °C, survival rate of Zebra II was higher than that of the Putian group. For both groups, the respiration, ammonia excretion, and ingestion rates continuously decreased till 0 with reductions temperature. In addition, RNA-seq revealed that as compared with the Putian group, there were 3682 up-regulated differentially expressed genes (DEGs) and 3361 down-regulated DEGs in Zebra II group. Moreover, Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses showed that these DEGs were mostly enriched in the purine, pyrimidine, and pyruvate metabolism pathways in Zebra II under low-temperature stress. Furthermore, qRT-PCR analysis further confirmed that Zebra II responded to low-temperature stress through upregulating genes involved in purine, pyrimidine, and pyruvate metabolism pathways. Taken together, all these results indicated that Zebra II has higher cold tolerance than the Putian group. Therefore, Zebra II is capable for overwintering in the intertidal zone of North China.

Abstract
Studies have shown that the shellfish have innate immune system, which is a very important immune form of shellfish, and they rely on the innate immune system to resist diseases. As a transcription factor, Microphthalmia-associated transcription factor (MITF) plays a regulatory role in immune response and the shell color is also an important index for the breeding of excellent varieties of R. philippinarum. The research on immune response mechanism of RPMITFs can provide important reference data for the breeding of excellent clam varieties. In the genome of R. philippinarum, the RPMITF genes family of shell color-related gene family was selected as the target gene of this experiment. There are 12 RpMITF genes named RpMITF1, RpMITF2, RpMITF3, RpMITF4, RpMITF5, RpMITF6, RpMITF7, RpMITF8, RpMITF9, RpMITF10, RpMITF11, and RpMITF12. The open reading frame length is 639, 1233, 996, 1239, 675, 624, 816, 1365, 612, 1614, 1122, and 486 bp, encoding 212, 410, 331, 412, 224, 207, 271, 454, 203, 537, 373, and 161 aa, respectively. The predicted molecular weight range of amino acids is 18.85-62.61 kda, and the isoelectric point range is 5.26-9.44. Real-time quantitative PCR was used to detect the gene expression of RpMITF gene family in hepatopancreas tissues of two populations of Manila clam at 6 time points (0, 3, 6, 12, 24, and 48 h) after Vibrio anguillarum stress. The results show that RpMITF gene family was significantly expressed in hepatopancreas of two clam populations after V. anguillarum stress (P < 0.05).

Abstract
To estimate the quality of mussels during storage, the mortality, succinate dehydrogenase (SDH) activity, extractive components, viable bacterial count (VBC), and bacterial flora of live mussels were investigated. The hierarchical cluster analysis, based on extractive components and VBC, taste active value (TAV), and equivalent umami concentration (EUC), suggested that metabolite composition, bacterial, and taste changing patterns of samples stored at 5 and 10°C differed from those stored at 0°C. The mortality of mussels stored at 5 and 10°C was lower than those at 0°C. The gills of live mussels stored at 0°C for more than 7 days exhibited significantly lower SDH activity than those stored at 5 and 10°C. There was no significant difference in EUC among the samples stored at different temperatures, but a significantly higher TAV of Ala and succinic acid was observed in live mussels after 12 days of storage at 5 and 10°C than in those stored at 0°C. Next-generation sequencing analysis showed that samples stored at 5 and 10°C lost bacterial diversity, and their bacterial flora changed compared to that before storage. Considering these results, the most suitable storage condition to maintain high quality for live mussels is 5°C for less than 7 days.

Abstract
The temperature has always been a key environmental factor in Manila clam (Ruditapes philippinarum) culture. In this study, the Manila clam was treated to different temperature pre-heat (28 °C, 30 °C) and gained heat tolerance after recover of 12 h, and a survival rate (14.7 %-49.1 %) advantage after high temperature challenge (30 and 32 °C). To further investigate the physiological and metabolism changes in Manila clam that had experienced a heat stress, non-targeted metabolomics (LC-MS/MS) was used to analyze the metabolic responses of gills in three group Manila clams during the heat challenge. Metabolic profiles revealed that high temperature caused changes in fatty acid composition, energy metabolism, antioxidant metabolites, hydroxyl compounds, and amino acids in heat-hardened clams compared to non-hardened clams. We found a number of significantly enriched pathways, including cAMP signaling pathway, serotonergic synapse, and biosynthesis of unsaturated fatty acids in heat-hardened Manila clam compared with non-hardened and untreated Manila clam. After a brief high temperature treatment, the physiological maintenance ability of Manila clam was improved. Combined with metabolomics analysis, heat hardening treatment may improve the energy metabolism and antioxidant ability of Manila clam. These results provide new insights into the cellular and metabolic responses of Manila clams following high temperature stress.

Abstract
Ruditapes philippinarum is a typical burrowing shellfish, living in the intertidal zone. In natural conditions, the mortality of R. philippinarum is most affected by high water temperatures, high temperature air-exposure, and other environmental stresses. In this study, the mortality rates of the two populations of R. philippinarum under high water temperature stress were recorded, and catalase (CAT), superoxide dismutase (SOD) and total antioxidant capacity (T-AOC) antioxidant enzyme activities in the hepatopancreas were analyzed. The results showed that the survival times of cultured clams were longer than those of wild clams after acute high temperature stress. CAT, SOD, and T-AOC activities increased after acute high water temperature and high temperature air-exposure stress. These antioxidant enzyme activities gradually decreased to their initial levels after 2 days of recovery from these high temperature stresses. Based on these experimental results, we found that the cultured clam population had better heat and high temperature air-exposure resistances than the wild clams. CAT, SOD, and T-AOC enzymes play an important role in the antioxidant processes of R. philippinarum in response to high water temperature and high temperature air-exposure. This study provided a theoretical basis for the development of healthy aquacultural practices for these shellfish.

COMPARATIVE BIOCHEMISTRY AND PHYSIOLOGY D-GENOMICS & PROTEOMICS 2021; 37:100788.

Abstract
Tyrosinase (EC1.14.18.1, TYR) is also called phenol oxidase, is not only involved in pigmentation but also plays an important role in modulating innate immunity in invertebrates. Tyrosinase is a copper containing metalloenzyme. The tyrosinase protein has two copper binding sites and three conserved histidines. In this study, 21 tyrosinase genes (RpTYR) were obtained from the whole genome of Ruditapes philippinarum. Their open reading frames were from 951 to 5424 aa, the range of predicted relative molecular weight from 36.72 to 203.81 kDa, and the range of isoelectric point from 4.72 to 9.88. Transcriptome analysis showed that RpTYR gene was expressed specifically in different developmental stages, adult tissues, four strains and two groups with different shell colors. Besides, the expression profiles of 21 RpTYRs were investigated against the immune response of R. philippinarum to a Vibrio challenge. The qPCR results showed that RpTYRs were involved in the immune response of R. philippinarum after Vibrio anguillarum challenge. This study provides preliminary evidence that the tyrosinases genes are involved in the immune defense and the potential immune function of R. philippinarum. Overall, these findings suggested that the expansion of TYR genes may play vital roles in larval development, the formation of shell color pattern, and immune response in R. philippinarum.

Abstract
Simple Summary Oysters and clams form an important component of the food chain and food security and are of considerable commercial value worldwide. They are affected by pollution and climate change, as well as a range of infections, some of which are opportunistic. For aquaculture purposes they are furthermore of great commercial value and changes in their immune responses can also serve as indicators of changes in ocean environments. Therefore, studies into understanding new factors in their immune systems may aid new biomarker discovery and are of considerable value. This study assessed new biomarkers relating to changes in protein function in four economically important marine molluscs, the blue mussel, soft shell clam, Eastern oyster, and Atlantic jacknife clam. These findings indicate novel regulatory mechanisms of important metabolic and immunology related pathways in these mollusks. The findings provide new understanding to how these pathways function in diverse ways in different animal species as well as aiding new biomarker discovery for Mollusca aquaculture. Abstract Oysters and clams are important for food security and of commercial value worldwide. They are affected by anthropogenic changes and opportunistic pathogens and can be indicators of changes in ocean environments. Therefore, studies into biomarker discovery are of considerable value. This study aimed at assessing extracellular vesicle (EV) signatures and post-translational protein deimination profiles of hemolymph from four commercially valuable Mollusca species, the blue mussel (Mytilus edulis), soft shell clam (Mya arenaria), Eastern oyster (Crassostrea virginica), and Atlantic jacknife clam (Ensis leei). EVs form part of cellular communication by transporting protein and genetic cargo and play roles in immunity and host–pathogen interactions. Protein deimination is a post-translational modification caused by peptidylarginine deiminases (PADs), and can facilitate protein moonlighting in health and disease. The current study identified hemolymph-EV profiles in the four Mollusca species, revealing some species differences. Deiminated protein candidates differed in hemolymph between the species, with some common targets between all four species (e.g., histone H3 and H4, actin, and GAPDH), while other hits were species-specific; in blue mussel these included heavy metal binding protein, heat shock proteins 60 and 90, 2-phospho-D-glycerate hydrolyase, GTP cyclohydrolase feedback regulatory protein, sodium/potassium-transporting ATPase, and fibrinogen domain containing protein. In soft shell clam specific deimination hits included dynein, MCM3-associated protein, and SCRN. In Eastern oyster specific deimination hits included muscle LIM protein, beta-1,3-glucan-binding protein, myosin heavy chain, thaumatin-like protein, vWFA domain-containing protein, BTB domain-containing protein, amylase, and beta-catenin. Deiminated proteins specific to Atlantic jackknife clam included nacre c1q domain-containing protein and PDZ domain-containing protein In addition, some proteins were common as deiminated targets between two or three of the Bivalvia species under study (e.g., EP protein, C1q domain containing protein, histone H2B, tubulin, elongation factor 1-alpha, dominin, extracellular superoxide dismutase). Protein interaction network analysis for the deiminated protein hits revealed major pathways relevant for immunity and metabolism, providing novel insights into post-translational regulation via deimination. The study contributes to EV characterization in diverse taxa and understanding of roles for PAD-mediated regulation of immune and metabolic pathways throughout phylogeny.
