Asymmetric expression patterns reveal a strong maternal effect and dosage compensation in polyploid hybrid fish

open access: yesBMC Genomics, 2018
Background Hybridization and polyploidization are regarded as the major driving forces in plant speciation, diversification, and ecological adaptation.

Analysis and Comparison on the Quality and Volatile Flavor Components of Crude Fish Oil from the Viscera of Three Freshwater Fishes

open access: yesShipin gongye ke-ji, 2023
In order to improve the high-value utilization of by-products from freshwater fish processing, crude fish oil was extracted from the viscera of three common freshwater fishes (grass carp, black carp and silver carp), and the physicochemical indexes ...

Diploid hybrid fish derived from the cross between female Bleeker’s yellow tail and male topmouth culter, two cyprinid fishes belonging to different subfamilies

open access: yesBMC Genetics, 2019
Background Bleeker’s yellow tail (Xenocypris davidi Bleeker, YT) and topmouth culter (Culter alburnus Basilewsky, TC) are both famous and important economic freshwater fish in China. YT, a kind of omnivorous fish, has strong resistance.

Comparative analyses of the Sox9a-Amh-Cyp19a1a regulatory Cascade in Autotetraploid fish and its diploid parent

open access: yesBMC Genetics, 2020
Background Autotetraploid Carassius auratus (4nRCC, 4n = 200, RRRR) was derived from the whole genome duplication of diploid red crucian carp (Carassius auratus red var.) (2nRCC, 2n = 100, RR).

Formation of the synaptonemal complex in a gynogenetic allodiploid hybrid fish

open access: yesFrontiers in Genetics, 2023
Introduction: The correct pairing and separation of homologous chromosomes during meiosis is crucial to ensure both genetic stability and genetic diversity within species. In allodiploid organisms, synapsis often fails, leading to sterility.

Optimal reference genes for gene expression analysis in polyploid of Cyprinus carpio and Carassius auratus

open access: yesBMC Genetics, 2020
Background Reference genes are usually stably expressed in various cells and tissues. However, it was reported that the expression of some reference genes may be distinct in different species.

Effective monitoring of freshwater fish [PDF]

open access: yesFish and Fisheries, 2019
AbstractFreshwater ecosystems constitute only a small fraction of the planet's water resources, yet support much of its diversity, with freshwater fish accounting for more species than birds, mammals, amphibians or reptiles. Fresh waters are, however, particularly vulnerable to anthropogenic impacts, including habitat loss, climate and land use change,

Carcinogens and Cancers in Freshwater Fishes [PDF]

open access: yesEnvironmental Health Perspectives, 1991
Epizootics of neoplasms in freshwater fish species are considered in relation to circumstantial and experimental evidence that suggest that some epizootics of neoplasia of hepatocellular, cholangiocellular, epidermal, and oral epithelial origin may be causally related to contaminant exposure.

Symmetric subgenomes and balanced homoeolog expression stabilize the establishment of allopolyploidy in cyprinid fish

open access: yesBMC Biology, 2022
Background Interspecific postzygotic reproduction isolation results from large genetic divergence between the subgenomes of established hybrids. Polyploidization immediately after hybridization may reset patterns of homologous chromosome pairing and ...

Interactions between mitochondrial and nuclear genomes and co-regulation of mitochondrial and nuclear gene expression in reciprocal intergeneric hybrids between Carassius auratus red var. × Cyprinus carpio L.

open access: yesReproduction and Breeding, 2021
Genetic interactions between nuclear and mitochondrial genomes always play an important role in growth and development. However, it is not feasible to directly perform these studies in some animals. The reciprocal hybrid fishes obtained from intergeneric
