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

Climate change and its implications for Australia's freshwater fish

open access: yes, 2011
Freshwater environments and their fishes are particularly vulnerable to climate change because the persistence and quality of aquatic habitat depend heavily on climatic and hydrologic regimes.

Exogenous paternal mitochondria rescue hybrid incompatibility and the destiny of exogenous mitochondria

open access: yesReproduction and Breeding, 2022
The mitochondria of most organisms follow strict maternal inheritance, and the mechanism of elimination of paternal mitochondria is unclear. Our previous studies showed that the paternal mtDNA presented in the embryo of hybrid Megalobrama Amblycephala ...

Heterosis of growth trait regulated by DNA methylation and miRNA in allotriploid fish

open access: yesEpigenetics & Chromatin, 2022
Background Heterosis of growth traits in allotriploid fish has benefited the production of aquaculture for many years, yet its genetic and molecular basis has remained obscure.

Diseases of freshwater fish

open access: yesVeterinary Quarterly, 1996
Dust and endotoxin exposure was measured in the Spring and Autumn in 96 veterinary practitioners, subdivided in four professional groups ((predominantly working with either swine, cattle, poultry, or companion animals). Furthermore, peak expiratory flow (PEF) variability was measured four times a day over a week in Spring and Autumn in order to detect ...

Molecular characterization and expression patterns of Nanog gene validating its involvement in the embryonic development and maintenance of spermatogonial stem cells of farmed carp, Labeo rohita

open access: yesJournal of Animal Science and Biotechnology, 2018
Background The homeobox containing transcription factor Nanog plays crucial roles in embryonic development/proliferation and/or maintenance of spermatogonial stem cells (SSCs) via interacting with transcription factors such as Oct4 and Sox2 in mammals ...

Glochidia ecology in wild fish populations and laboratory determination of competent host fishes for an endemic freshwater mussel of south-western Australia

open access: yes, 2012
Glochidia (parasitic larvae) of freshwater mussels generally require a fish as a host. Westralunio carteri Iredale, 1934 (Bivalvia : Hyriidae), the only freshwater mussel found in south-western Australia, was listed as Vulnerable, but recently changed to

Rapid genomic DNA variation in newly hybridized carp lineages derived from Cyprinus carpio (♀) × Megalobrama amblycephala (♂)

open access: yesBMC Genetics, 2019
Background Distant hybridization can generate changes in phenotypes and genotypes that lead to the formation of new hybrid lineages with genetic variation.

Regulation of hormonal receptors of the hypothalamic-pituitary-gonadal axis by ghrelin in ovary of grass carp (Ctenopharyngodon idella)

open access: yesAquaculture Reports, 2023
Ghrelin has been well known as an orexigenic hormone that regulates appetite and energy metabolism in animals. Recent studies imply the regulatory function of ghrelin on ovary development, however, the mechanism about the effects of ghrelin on key ...
