Summary: This paper reviews the use of genomic tools and breeding techniques in mollusc breeding programs, focusing on the Portuguese oyster. Controlling the life cycle in hatcheries can improve spat supply sustainability and reliability. Genomic technology enhances understanding of mollusc genetics and contributes to the enhancement of morphometric traits and disease resistance.

Summary: The mitochondrial genome of the fingerprint oyster Alectryonella plicatula was found to be misidentified as it actually represents an individual of M. gigas. This highlights the importance of not relying solely on morphological shell analysis for oyster identification, even at high taxonomic ranks. The study emphasizes that morphological identification of oysters should be validated by molecular data, and molecular data should also be taxonomically verified through DNA barcoding and phylogenetic analyses.

Summary: This study investigated the effects of temperature on the bioaccumulation and depuration processes of Crassostrea gigas exposed to Cd, as well as its molecular responses. The results showed that the concentration of Cd in different tissues varied at different temperatures, and both uptake rate and elimination rate were influenced by temperature. Additionally, the expression of metallothionein and P-glycoprotein also showed temperature-dependent changes.

Summary: This study found that C. gigas has a growth advantage over C. angulata in Shantou waters, oysters at low stocking density generally outperformed those at high stocking density, and lipid composition of oysters is not affected by ploidy and stocking density.

Summary: This study used Pacific oysters as a model to investigate apoptotic responses and regulation mechanisms under short- and long-term CO2 exposure. The findings suggest a variety of apoptosis regulation mechanisms exist during different exposure periods, with CgBcl-XL playing a crucial antiapoptotic protein role under long-term CO2 exposure.

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: Many marine invertebrate phyla undergo indirect development, transitioning from planktonic larvae to benthic spats through settlement and metamorphosis. Understanding the molecular regulation dynamics during metamorphosis is crucial for understanding the origin and evolution of indirect development. This study examined the gene expression patterns and open chromatin region changes during metamorphosis using metamorphosis-competent pediveligers of the Pacific oyster. The findings revealed significant differences in gene regulation networks before, during, and after metamorphosis, suggesting the involvement of various genes and molecular processes in oyster metamorphosis.

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: Genetic improvement for quality traits in aquaculture has been limited, however, genotyping technologies provide an opportunity to enhance selection efficiency. This study assessed the potential of using genomic information to improve meat yield, body shape, and color traits in Portuguese oysters. The results showed high heritability estimates for meat yield traits and favorable genetic correlations among whole weight, meat yield, and body shape traits, indicating good prospects for genetic gain.

Summary: This study focused on the genetic variance, correlation, and genotype by environment interactions of harvest whole weight and uniformity in the Portuguese oyster in different environments. The results showed low heritability estimates for uniformity, no re-ranking of oysters across environments, and no potential to improve uniformity while increasing harvest weight.

Summary: The study investigated the structure and stability characteristics of oyster ferritin by adding Fe2+ to it. The results showed that the protein structure of ferritin remained largely unchanged after adding Fe2+ and the sample with 1000 Fe2+ exhibited good stability under storage and high temperature conditions.

Summary: This study detected the abundance and characteristics of microplastics (MPs) in farmed oyster shells off the coast of Taiwan. The results showed that MPs were ubiquitous in oyster shells, with a higher abundance in small oyster shells and inorganic fraction. There was no significant difference in MPs abundance between the top and bottom shells.

Summary: This study investigates the IgE sensitisation profiles of patients with oyster allergy to raw and heated Pacific oyster extract. Tropomyosin is identified as the major allergen responsible for oyster allergy, and the study also reveals partial cross-reactivity and/or co-sensitisation between oyster, prawn, and dust mite allergens. This research emphasizes the importance of using recombinant tropomyosin in improved diagnostics and immunotherapy.
