Summary: Understanding the genetic basis and coordination of trait variations in different environmental conditions is crucial in evolutionary biology. In this study, metabolic and transcriptomic analyses of two oyster species revealed that one species allocated more energy to storage and defense, while the other species prioritized growth, reflected in its stronger aerobic capacity and higher levels of growth-related biomarkers. This research sheds light on the evolution of growth-defense trade-offs and energy allocation in marine ectotherms.

Summary: The Portuguese oyster, Crassostrea angulata, is important in aquaculture due to its fast growth and good edibility, but genetic improvement is needed to address issues like small adult size and flat meat quality. Hybridization experiments show that reciprocal triploid hybrids outperform traditional intra-ploidy groups.

Summary: The development of two new types of triploid hybrids by inhibiting the polar body II has shown superior growth, survival, and gonad traits compared to diploid hybrids and purebred crosses. Triploid hybrids outperformed diploid hybrids in growth and survival across different culture environments, especially in summer, showing a positive yield advantage. The findings indicate that triploid hybrids have important application value for commercial oyster cultivation in northern China.

Summary: The role of oyster microbiota in Pacific oyster mortality syndrome (POMS) is not fully understood. This study describes the temporal kinetics of POMS and the changes in microbiota during infection, and identifies both harmful and beneficial bacteria that may influence disease outcomes. These findings open new perspectives on using microbiome composition as a screening tool for shellfish health and predicting oyster vulnerability to POMS.

Summary: This study identified 66 TRP genes in Pacific oyster with significant gene expansion and tandem duplication. The analysis of RNA-Seq data after acute heat stress revealed a set of heat-inducible TRPs. Further study under chronic heat stress and comparison between two oyster species led to the identification of TRPC3.6, TRPC3.7, and TRPV4.7 as important TRPs involved in thermal regulation in oysters.

Summary: The study found that the thermal responses of native oysters and invasive oysters to marine heat waves were context dependent, with native oysters showing changes in size and biomass while invasive oysters remained unaffected. The ability of native oysters to maintain their presence in the intertidal under sufficient food supply was highlighted, while the resilience of invasive oyster populations to climatic extremes may lead to competitive exclusion and further decline in native oyster populations. These findings are crucial for developing effective management plans to ensure the sustainability of natural oyster populations and maintaining key ecosystem functioning.

Summary: This study investigated the virucidal effect of cold atmospheric plasma on two surrogate viruses in culture medium, showing greater immediate reduction in single-stranded RNA virus. CAP treatment resulted in a decline in glucose content in DMEM, and a decrease in pH in salt water used in oyster production. Further research is needed to explore the deposition of additional nitrogen in oyster flesh from CAP treatment.

Summary: Triploid oysters are widely cultivated in China and other countries due to their fast growth, infertility, and good meat quality. However, triploid Crassostrea gigas experience slow growth and high mortality, while triploid C. angulata have fragile shells and a high ratio of developed gonads. Hybridization between tetraploid males and diploid females has been found to be the best method for improving triploids. This study investigated the growth, survival, and gonad development of autotriploids (DGTG and DATA) and allotriploids (DATG and DGTA), and found that DATG had faster growth and higher survival in southern China while DGTA had advantages in growth, survival, and infertility in northern China.

Summary: The addition of terminal tags to caerin significantly reduces its antiviral activity against studied viruses, with varying effects on bactericidal activity against different bacterial species. However, caerin with a 6xHis extension at its N terminus maintains or increases its antimicrobial activity against most fish pathogenic bacteria. The experimental observations show only a moderate agreement with theoretical predictions, highlighting the need for further research in the rational design of strategies for recombinant production of antimicrobial peptides in aquaculture.

Summary: This study investigates the role of various pathogens in the mass mortality event (MME) of the fan mussel Pinna nobilis in the Mediterranean Sea. The researchers found that infection by Haplosporidium pinnae played a major role in the onset and spread of the MME, while infection with mycobacteria was independent of the MME and associated with host size. Gram (-) bacteria were not associated with the MME.

Summary: The complete mitochondrial genome of the striped soldier shrimp, Plesionika edwardsii, was sequenced and assembled in this study. Comparative analysis revealed similarities in gene order and nucleotide content with other caridean mitochondrial genomes. Additionally, mutations in some genes were detected. A conserved sequence block and microsatellites were found in the control region of P. edwardsii.
