miR-199-5p regulates spermiogenesis at the posttranscriptional level via targeting Tekt1 in allotriploid crucian carp

open access: yesJournal of Animal Science and Biotechnology, 2022
Background Sperm abnormalities are one of the primary factors leading to male sterility, but their pathogenesis is still unclear. Although miRNAs are suggested to exert important roles in the regulation of spermatogenesis at both transcriptional and ...

N-acetylhistidine, a novel osmolyte in the lens of Atlantic salmon (Salmo salar L.) [PDF]

open access: yes, 2010
Volume homeostasis is essential for the preservation of lens transparency and this is of particular significance to anadromous fish species where migration from freshwater to seawater presents severe osmotic challenges. In Atlantic salmon (Salmo salar L.)

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) (♂).

Hox genes reveal variations in the genomic DNA of allotetraploid hybrids derived from Carassius auratus red var. (female) × Cyprinus carpio L. (male)

open access: yesBMC Genetics, 2020
Background Hox transcription factors are master regulators of animal development. Although highly conserved, they can contribute to the formation of novel biological characteristics when modified, such as during the generation of hybrid species, thus ...

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.

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.

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.

Comparative Transcriptome and DNA methylation analyses of the molecular mechanisms underlying skin color variations in Crucian carp (Carassius carassius L.)

open access: yesBMC Genetics, 2017
Background Crucian carp is a popular ornamental strain in Asia with variants in body color. To further explore the genetic mechanisms underlying gray and red body color formation in crucian carp, the skin transcriptomes and partial DNA methylation sites ...
