In our case, unsorted gonadal cells from a donor species injected near the genital ridge of a sterile surrogate should colonize only that region, eventually becoming donor gametes. Unsorted gonadal cells from blue catfish (<i>Ictalurus furcatus</i>) injected into triploid common carp (<i>Cyprinus carpio</i>) embryos and fry were detected by PCR assays predominantly in recipient gonads and, in a subset of individuals, occasionally in DNA extracts from pectoral fin, anal fin, or muscle tissue, resulting in mosaicism in these tissues (presence of donor DNA/cells). Recipients retained normal common carp morphology. Donor signal was not detected in other assayed tissues, including eyes, livers, intestines, and hearts. This is the first report of such aberrant, presumably gonadal stem cell migration and colonization outside the gonads in xenogenic fish. Individuals injected later in development had reduced or no mosaicism compared to those injected at early developmental stages. Catfish donor cells were detected in the gonad, muscle, anal fin, and pectoral fin of both diploid and triploid common carp hosts. The incidence of non-target tissues containing blue catfish DNA trended towards being higher in triploids than diploids, especially when mosaicism involved three tissues. These findings provide preliminary insights into donor unsorted gonadal cell migration, tissue-specific persistence, and developmental timing in reproductive biology. These PCR findings indicate tissue mosaicism but do not establish somatic differentiation.</p></div>","PeriodicalId":690,"journal":{"name":"Marine Biotechnology","volume":"27 6","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145720309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The parasite species was identified via Polymerase Chain Reaction (PCR), while infection prevalence, abundance, and infection grade classification were assessed using Ray’s Fluid Thioglycolate Medium (RFTM) culture.

Of approximately 11,000 sequenced vertebrate genomes, genomes of teleost fish represent about 30%, with reference genome sequences available for most aquaculture fish species. While such progress has accelerated progress in aquaculture genetics research and breeding, it is clear that understanding of full genomic variations among aquaculture species is lacking. This is largely because of the way reference genomic sequences were produced, with a single or just a few genomes being sequenced. In addition, haplotype variations and their representation in the species or population are unknown. This hinders understanding of genomic basis of phenotypic variations relevant to performance and production traits such as growth rates, feed conversion efficiency, disease resistance, stress responses, processing yields, and reproductive traits, among other traits, especially so with strain-specific performance traits. The pangenome refers to a whole collection of genomic sequences found in the entire species or population rather than in a single individual, as represented in reference genomes. Pangenome includes the core genome sequence that are shared in all individuals, and variable or dispensable genome sequence found in a subset of individuals, representing intraspecies genomic variations.

However, the complexity of stress responses, which are regulated by multiple genes, limits the effectiveness of single-gene approaches in accurately reflecting stress status. Transcription factors (TFs) are promising candidates for comprehensively assessing stress responses, as they regulate numerous stress-responsive genes. In this study, we present a framework for identifying TF indicators that reflect the stress status of Pacific oysters (<i>Crassostrea gigas</i>). Specifically, oysters were exposed to high, medium, and low tide conditions to assess the physiological responses of oysters to tidal-induced stress. Enrichment analysis of differentially accessible chromatin peaks derived from assay for transposase-accessible chromatin sequencing (ATAC-seq) identified several key TFs. Among these, <i>CCCTC-binding factor</i> (<i>Cg</i>-<i>CTCF</i>) and <i>MYB proto-oncogene A</i> (<i>Cg-MYBA</i>) were significantly upregulated under tidal-induced stress and occupied critical positions in regulatory networks, as indicated by RNA-seq. RNA interference experiments confirmed that both genes contribute to enhancing survival under heat stress, a major stressor affecting oysters. Additionally, field experiments demonstrated significant upregulation of these genes under natural stress conditions, suggesting their potential as indicators for oyster reef management. To our knowledge, this is the first study on the coastal invertebrate to combine ATAC/RNA-seq with in vivo TF knockdown and field validation to propose TFs as practical stress indicators. We advocate for the broad application of our framework to explore TFs as molecular indicators of health status in marine organisms, thereby enabling informed strategies for conservation management.</p></div>","PeriodicalId":690,"journal":{"name":"Marine Biotechnology","volume":"27 6","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10126-025-10539-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145538257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
