Summary: In this study, whole genome resequencing was used to genotype 716 individuals of Trachinotus ovatus, resulting in the identification of 4,886,850 high-quality single nucleotide polymorphisms (SNPs). A genome-wide association study (GWAS) revealed 107 significant SNPs and 108 related genes associated with growth traits such as body weight and body length. The identified SNPs and genes were found to be significantly enriched in terms related to muscle growth, anabolism, and bone development. This study provides valuable insights into the genetic architecture of growth-related traits and offers molecular markers for future genome-wide selection breeding of T. ovatus.

Summary: This study investigated the effects of TPT exposure on osmoregulation and energy metabolism in gill under different salinity. The results showed that TPT exposure caused changes in gill tissue morphology and affected the expression of related genes. Furthermore, TPT exposure at different salinity levels also influenced the activities of Na+- K+-ATPase, Ca2+-Mg2+-ATPase, succinate dehydrogenase, and lactate dehydrogenase in the fish.

Summary: This study investigated the effects of salinity fluctuations on the Antarctic harpacticoid copepod Tigriopus kingsejongensis, finding that female copepods were more tolerant to hypo- and hypersalinity compared to males. Lifespan was significantly shortened under hypo- and hypersalinity, but there was no significant difference in sex ratio between salinity treatments. Multigenerational experiments showed that exposure to certain salinities reduced body length compared to control.

Summary: Pompano is an important economic marine fish in the south coast of China. The research on the basic biology of pompano is currently weak, affecting its development. This study investigated the effects of sbGnRH peptides on the physiology and metabolic enzyme activities of pompano liver, and analyzed the differences in gene expression after injection of sbGnRH peptides through transcriptome sequencing. The results provide a theoretical basis for studying the effects of sbGnRH on liver physiology, biochemistry, and metabolic enzyme activities in pompano.

Summary: In this study, two isoforms of caspase-8, ToCas8 and ToCas8-like, were identified in golden pompano. These two proteins showed similarity to their counterparts in other vertebrates and exhibited typical features of the Caspase-8 protein family. They were widely distributed in various tissues and significantly upregulated in response to pathogen challenges, indicating their involvement in the immune response. These findings contribute to our understanding of the evolutionary history and functional characteristics of caspase-8 genes in vertebrates.

Summary: This study aimed to evaluate the function of manganese in Trachinotus ovatus immune protection against Crytocaryon irritans. The results showed that manganese enhanced monocyte phagocytosis, increased expression levels of immune factors, and improved pompano immunity. The colloidal manganese salt also provided immune protection and activated the cGAS molecule. These findings suggest that manganese could be a promising adjuvant candidate for C. irritans vaccine.

Summary: This study investigated the effects of salinity on the growth and health of Urechis unicinctus, a species thriving in intertidal sediments. The results showed that U. unicinctus is a euryhaline species that can tolerate a wide range of salinity. The optimal salinity for growth was found to be 30 parts per thousand. Salinity had significant effects on the physiological characteristics and intestinal microbiota composition of U. unicinctus. Specific bacteria were identified to play important roles in high salinity acclimation, while others were important for low salinity acclimation.

Summary: Golden pompano has become an economically important fish in China, but it suffers from considerable economic losses due to the parasitic ciliate Cryptocaryon irritans. To understand the pathogenesis of C. irritans in golden pompano, the researchers analyzed the pathological properties, immune-related enzyme activity, and expression of the NEMO gene. The results showed significant metamorphosis, hyperplasia, leukocyte aggregation, and mucous cell increases in the parasitized skin. Moreover, the activities of four enzymes and the expression of the ToNEMO gene were significantly increased after C. irritans infection.

Summary: In this study, ten different CpG ODNs were designed and synthesized to study the antibacterial immune responses of CpG ODNs in golden pompano. Results showed that CpG ODN 2102 significantly improved the immunity of golden pompano against bacteria and promoted the proliferation of head kidney lymphocytes and activation of head kidney macrophages.

Summary: Gymnocypris przewalskii, a native cyprinid fish in Lake Qinghai, is capable of adapting to different salinity levels. The study reveals that G. przewalskii undergoes gill remodeling to enhance ion uptake in response to low salinity. Gene expression analysis further identifies key pathways involved in ion transport, cell-cell adhesion, and mucus secretion during osmoregulation in G. przewalskii.

Summary: Acute low-salinity stress leads to stress responses in black seabream, but with time, the fish show signs of adaptation to the environmental change. Low salinity stress increases the synthesis of long-chain polyunsaturated fatty acids in the gills, enhancing the fish's osmoregulation ability.

Summary: This study investigated the immune response of Trachinotus ovatus to reinfection with Amyloodinium ocellatum. Transcriptome analysis revealed significantly increased expression of immune-related genes, particularly in the secondary infection group. The load of A. ocellatum did not differ between the primary and secondary infection groups, but the serum levels of certain indicators were significantly abnormal in the primary infection group. These findings contribute to understanding the defense mechanisms of fish skin against ectoparasite infection.

Summary: Understanding the morpho-physiological behaviors of borage plants under salinity and drought stress is important due to the global demand for medicinal plants and the upcoming climate change. This study found that both salinity and drought stress caused plant damage, antioxidant defense, and increased osmolyte levels, but drought stress had a greater negative effect on growth and development. Borage plants had the ability to absorb and accumulate sodium, controlling its toxic effects and using them for osmoregulation. Drought stress delayed reproductive growth and flowering, impairing overall plant growth. The study also showed that borage plants had better growth potential under salinity stress compared to drought stress by controlling the negative effects of salt ions and allocating lower energy to osmoregulation.
