Summary: GWAS analysis revealed the genetic basis of shell color in bay scallops, identifying key SNPs mainly located on chromosome 7 and three candidate genes involved in shell pigmentation regulation. Gene expression analysis showed significant differences in the expression levels of candidate genes in mantle tissues of individuals with different shell colors, providing insights into the mechanism underlying shell color phenotype differences.

Summary: The study found that the genetic variations in bay scallop growth traits are mainly caused by additive effects for shell height and length, and by dominance effects for shell width and body weight. Including insignificant inbreeding in genomic prediction model is unnecessary, and it is suggested to optimize the genomic prediction model with likelihood ratio tests and cross-validation before practical application.

Summary: The study identified 1,906 significant SNPs associated with thermal tolerance in bay scallops using GWAS, revealing potential regulatory genes for thermal tolerance improvement. The findings suggest that the AiPC4 gene may act as a positive regulator of thermal tolerance in bay scallops, providing valuable insights for molecular breeding aiming at enhancing thermal tolerance in this species.

Summary: Animals with distributed visual systems consolidate visual information early in their sensory-motor pathways, exhibiting the ability to detect visual cues but lacking spatial vision. Through studying the bay scallop Argopecten irradians, researchers found that they possess both spatial resolution and spatial vision, indicating neural representations of their visual surroundings in their sensory-motor circuits.

Summary: This study used stable isotope labeling to investigate the contributions of different sources of cadmium to scallop tissues. The accumulation pattern of cadmium in tissues during growth was significant in the viscera and gills. Additionally, a multi-omics approach revealed a network of oxidative stress-induced toxicity mechanisms of cadmium in scallops. Differential gene and protein expression related to metal ion binding, oxidative stress, energy metabolism, and apoptosis were identified.

Summary: Warming temperatures and diminishing dissolved oxygen concentrations have negative impacts on the physiology and survival of the northern bay scallop across its geographic distribution. The combined effects of thermal and hypoxic stress can increase mortality and reduce scallop clearance rates. Understanding the vulnerability of marine organisms to these stressors is important for the management and conservation of coastal ecosystems.

Summary: This study investigated the response mechanism of the bay scallop southern subspecies to low and high thermal stresses through transcriptomic and metabolomic analyses. The results revealed that differentially expressed genes were enriched in calcium ion, lipid-related pathways, and RNA processing pathways under thermal stress. Metabolomic analyses showed that retinol metabolism, inositol phosphate metabolism, and phosphatidylinositol pathways may be involved in the response to high thermal stress. The degradation of valine, leucine, and isoleucine and the tricarboxylic acid cycle were identified as major events induced by low and high thermal stress.

Summary: The increased frequency of marine heat waves (MHWs) caused by global climate change poses a threat to the survival of economic bivalves, such as the bay scallop Argopecten irradians irradians in northern China. This study examined the cardiac performance, oxidative impairment, and molecular responses of bay scallop hearts under simulated MHWs. The findings revealed dynamic molecular responses at the transcriptome level and identified the crucial role of CALR in the thermotolerance of bay scallops.

Summary: The scallop Chlamys farreri is an important bivalve species cultured in northern China, but has suffered mass mortalities since 1996, likely caused by an intracellular Rickettsiales-like prokaryote (RLP). Through analysis of the 16S rDNA sequence, a novel prokaryote named Sinorickettsia chlamys sp.nov. was identified as the causative agent. Specific DNA probes were designed for detection, confirming the presence of the RLP in infected tissues of C. farreri.

Summary: In this study, transgenic lines of the marine microalga Tetraselmis subcordiformis harboring antimicrobial peptide NZ2114 were created as an oral drug-delivery system in shellfish aquaculture. The results showed that the survival rate of pathogen-infected scallops fed with transgenic T. subcordiformis was much higher compared to those fed with wild-type algae.

Summary: The study revealed that B[a]P induced an increase in oxidative stress and oxidative damage in hemocytes, while mediating hemocyte apoptosis through both the mitochondrial apoptosis pathway and death receptor apoptosis pathway. Additionally, BPDE and MAPKs may play significant roles in the B[a]P-mediated apoptosis pathway.

Summary: Semicarbazide is considered a characteristic metabolite of nitrofurazone and is used as a marker for monitoring illegal nitrofurazone use in foods. Recent studies have shown that semicarbazide pollution can accumulate in aquatic organisms and threaten marine shellfish, ecological balance, and human health. The research found that scallops can uptake semicarbazide from seawater, potentially impacting the quality and safety of products used as food sources.

Summary: This study aims to investigate the effects of benzo(a)pyrene (B[a]P) on the immunity of Chlamys farreri and explore its potential molecular mechanism. Multiple biomarkers were used to assess these effects, and it was found that B[a]P had concentration-dependent immunotoxicity, possibly affecting immunity through the detoxification metabolic system, neuroendocrine system, and cell apoptosis pathway.

Summary: Maintenance of a balance between viral replication and selective pressure from insect vectors' immune systems is crucial for efficient transmission of insect-borne phytoviruses, with the mechanisms of RNA virus adaptation to insect vectors remaining largely unknown. In this study, researchers found that terminal extensions in the genome of rice stripe virus (RSV) can suppress viral replication in insect vectors by interfering with a key structure, and endogenous insect microRNA can relieve this inhibitory effect. However, RSV infection negatively regulates the expression of this microRNA, highlighting an intricate coordination between viral genome variation and insect microRNAs in controlling RSV replication in planthopper vectors.

Summary: The research revealed unique genomic differences in locusts compared to fruit flies, with lower transcription initiation precision and fewer distance constraints. Additionally, stricter exon length constraints and widespread expression of distant core promoters were found in locusts. The study provides new insights into the impact of genome size expansion on distant transcription initiation.

Summary: This study identifies a novel function of Piwi and piRNAs in regulating food intake in locusts. Knockdown of Piwi1 expression leads to reduced food consumption and body weight, potentially through decreased expression of neuropeptide NPF1. Mechanistically, intronic piRNAs may enhance RNA splicing of NPF1 by preventing hairpin formation at the branch point sites. This discovery reveals a novel nuclear PIWI/piRNA-mediated mechanism that controls food intake in the locust nervous system.

Summary: This study analyzed RNA viromes of field-caught mosquitoes from Hainan Island, China, and found that virome composition is influenced by mosquito species and food sources. Most RNA viruses remained stable across three years and different locations, indicating species-specific viromes in Hainan Island. However, virome compositions of single mosquito species in different geographic regions worldwide were visibly distinct, consistent with differences in the widespread distribution of mosquito food sources.
