    Abstract Phosphorylation is a post-translational modification that contributes to versatile protein functions in spermatogenesis, and the variations they generate usually results in abnormal spermatogenesis or sperm dysfunction. The sex-reversal phenomenon exists in Chinese tongue sole under certain conditions such that individuals with a ZW genotype can acquire a male phenotype and are thus called pseudomales. Pseudomale tongue sole can reach sexual maturity but produce only Z-type sperm, and the Z sperm carries paternal epigenetic information. Whether phosphorylation plays a role in the sperm abnormality of pseudomales is unknown. In this study, a phosphoproteomic analysis was performed to compare protein phosphorylation profiles between pseudomale and male testes. Altogether, we identified 14,253 phosphopeptides matching with 4843 proteins, with 1329 differentially phosphorylated peptides corresponding to 1045 differentially phosphorylated proteins (DPPs). Phosphorylation at 781 sites was upregulated and at 548 sites was downregulated. Four motifs were identified among differentially phosphorylated peptides, which were "SP", "SD", "RxxS", and "TP". Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses suggested that the cell cycle and DNA/RNA processing were significantly enriched with the genes encoding DPPs. To analyze DPP function in depth, a protein-protein interaction network was constructed, and Ran-binding protein 2 was found to play a central role in spermatogenesis by regulating several processes such as the cell cycle, eukaryotic translation, ubiquitination, and minichromosome maintenance. In kinase-associated network analyses, two "mitogen-activated protein kinase (Mapk)-centered" clusters were identified that may account for abnormal spermatogenesis in pseudomales. One cluster was centered on Mapk6, which predominantly regulated the cell cycle by interacting with several cyclin-dependent kinases, and the other was centered on the "testis-expressed kinase 1-like (Tesk1l)/Pim1l-Mapk4l- testis-expressed 14 (Tex14)" kinase cascade, which might contribute to spermatogenesis by regulating β-catenin. Taken together, these data suggested the new candidates involved in pseudomale sperm abnormalities and provided clues to discover the phosphorylated regulatory mechanism underlying tongue sole spermatogenesis.

    Abstract Patched (Ptch) is a receptor in the hedgehog signaling pathway, essential for animal development. Our previous study showed that ptch1 gene participates in the maintenance of the male germline and spermatogenesis in Cynoglossus semilaevis (csptch1). In this study, we identified a patched1 gene homolog (csptch1 x1). The csptch1 x1 gene is 5761 bp long, with a 4638 bp coding sequence that encodes 1545 amino acids. The Csptch1 x1 protein has 12 transmembrane regions and sterol-sensing domains and is highly homologous to the csptch1 (91 amino acids difference). Expression pattern analysis showed that csptch1 x1 is expressed in eight different tissues of adult tongue sole, and the expression is significantly higher in tissues of female than that in male tissues. The expression pattern in developmental stages was also analyzed. csptch1 x1 could be detected at the 1-cell stage and was highly expressed at the blastocyst, somite, and blastopore closing stages, implying that it participates in cell differentiation. In ovarian development, the expression of csptch1 x1 was initiated at 20 days after hatching (dah) and was significantly high at 35-50 and 95-150 dah. In situ hybridization showed that csptch1 x1 was predominantly expressed in primordial germ cells, oocytes, and follicular cells, but the expression of the gene was lower in the testis. These results suggest that csptch1 x1 may be mainly involved in female differentiation and ovarian development, different from the role of csptch1 in spermatogenesis.

    Abstract Aquaculture is becoming the primary source of seafood for human diets, and farmed fish aquaculture is one of its fastest growing sectors. The industry currently faces several challenges including infectious and parasitic diseases, reduced viability, fertility reduction, slow growth, escapee fish and environmental pollution. The commercialization of the growth-enhanced AquAdvantage salmon and the CRISPR/Cas9-developed tilapia (Oreochromis niloticus) proffers genetic engineering and genome editing tools, e.g. CRISPR/Cas, as potential solutions to these challenges. Future traits being developed in different fish species include disease resistance, sterility, and enhanced growth. Despite these notable advances, off-target effect and non-clarification of trait-related genes among other technical challenges hinder full realization of CRISPR/Cas potentials in fish breeding. In addition, current regulatory and risk assessment frameworks are not fit-for purpose regarding the challenges of CRISPR/Cas notwithstanding that public and regulatory acceptance are key to commercialization of products of the new technology. In this study, we discuss how CRISPR/Cas can be used to overcome some of these limitations focusing on diseases and environmental release in farmed fish aquaculture. We further present technical limitations, regulatory and risk assessment challenges of the use of CRISPR/Cas, and proffer research strategies that will provide much-needed data for regulatory decisions, risk assessments, increased public awareness and sustainable applications of CRISPR/Cas in fish aquaculture with emphasis on Atlantic salmon (Salmo salar) breeding.

    Abstract Turbot (Scophthalmus maximus), commercially important flatfish species, is widely cultivated in Europe and China. With the continuous expansion of the intensive breeding scale, turbot is exposed to various stresses, which greatly impedes the healthy development of turbot industry. Here, we present an improved high-quality chromosome-scale genome assembly of turbot using a combination of PacBio long-read and Illumina short-read sequencing technologies. The genome assembly spans 538.22 Mb comprising 27 contigs with a contig N50 size of 25.76 Mb. Annotation of the genome assembly identified 104.45 Mb repetitive sequences, 22,442 protein-coding genes and 3,345 ncRNAs. Moreover, a total of 345 stress responsive candidate genes were identified by gene co-expression network analysis based on 14 published stress-related RNA-seq datasets consisting of 165 samples. Significantly improved genome assembly and stress-related candidate gene pool will provide valuable resources for further research on turbot functional genome and stress response mechanism, as well as theoretical support for the development of molecular breeding technology for resistant turbot varieties.

    Abstract Interleukin 10 (IL-10), a pleiotropic cytokine, plays an essential role in multiple immunity responses. In the current study, the sequences of IL-10 family were identified from spotted knifejaw (Oplegnathus punctatus) whole genome, and O. punctatus IL-10 (OpIL-10) was cloned and characterized. OpIL-10 encodes 187 amino acids with a typical IL-10 family signature motif and predicted α-helices. It shared high identities with Notolabrus celidotus IL-10 and Epinephelus Lanceolatus IL-10. OpIL-10 was widely detected in healthy tissues, with the abundant expression in liver and skin. It was significantly up-regulated in the six immune-related tissues (liver, spleen, kidney, intestine, gill and skin) after infection against Vibrio harveyi and spotted knifejaw iridovirus (SKIV). Dual-luciferase analysis showed that OpIL-10 overexpression could suppress the activity of NF-κB. Meanwhile, OpIL-10 knockdown caused the down-regulation of five immune-related genes in JAK2/STAT3 signaling pathway and NF-κB signaling pathway, including IL-10R2, TYK2, STAT3, NOD2, and IκB. In addition, LPS and poly I:C stimulated expression of pro-inflammatory cytokines, including IL-6, IL-1β, IL-8, and IL-12, were lower with recombinant OpIL-10 (rOp IL-10) than the control group, indicating the anti-inflammatory roles of rOpIL-10. Taken together, these results indicated OpIL-10 as a negative regulator in the inflammatory responses of spotted knifejaw against bacterial and viral infection, which would help us better understand the role of IL-10 in teleost immunity.

    Abstract Megalocytivirus (MCV) is emerging as a major viral pathogen in aquaculture and has caused substantial economic losses due to its wide infectious spectrum. As the spotted knifejaw (Oplegnathus punctatus) is one of the most susceptible fish to MCV, the MCV infection in spotted knifejaw caused massive mortality, therefore significantly hampers the farming industry. Despite of the significant economic importance, the immune response of spotted knifejaw during MCV infection is still unclear, which limits the breeding of resistant fish lines and becomes a research priority for aquaculture worldwide. In this study, we challenged spotted knifejaw with a spotted knifejaw MCV strain (SKIV-SD) and performed a transcriptomic analysis using spleen samples from five different time points (days 0, 1, 4, 7, and 10). Fifteen samples (three for each time point) were employed to construct the RNA libraries. A total of over 100 Gb of clean bases was generated, and the clean reads per library ranged from 39.37 M to 60.87 M. A total of 23,365 genes were annotated, and 32,542 new transcripts were identified. Through a comparative transcriptomic analysis of the five groups, the nucleotide binding oligomerization domain-like (NOD-like) receptor signalling pathway, haematopoietic cell lineage, and cytosolic DNA-sensing pathway were closely related to MCV challenge, and the gene expression levels in these pathways were validated by qPCR. Our data provide a genetic resource and shed light on the immune response to MCV infection in spotted knifejaw.
