A new type of homodiploid fish derived from the interspecific hybridization of female common carp × male blunt snout bream

open access: yesScientific Reports, 2017
It is commonly believed that hybridization might lead to the formation of new polyploidy species, but it is unclear whether hybridization can produce a new homodiploid species.

Hox genes reveal genomic DNA variation in tetraploid hybrids derived from Carassius auratus red var. (female) × Megalobrama amblycephala (male)

open access: yesBMC Genetics, 2017
Background Allotetraploid F1 hybrids (4nF1) (AABB, 4n = 148) were generated from the distant hybridization of Carassius auratus red var. (RCC) (AA, 2n = 100) (♀) × Megalobrama amblycephala (BSB) (BB, 2n = 48) (♂).

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.

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.

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.

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).

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

Evidence for paternal DNA transmission to gynogenetic grass carp

open access: yesBMC Genetics, 2019
Background Grass carp (Ctenopharyngodon idellus, GC), as the highest-output fish in China, is economically important. The production of gynogenetic grass carp (GGC) will provide important germplasm resource for producing improved GC.

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 ...

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 ...
