Evidence for Paternal Mitochondrial DNA Leakage in Diploid Hybrid Fish Lineages

open access: yesAnimals
Distant hybridization induces genomic instability in offspring, driving the occurrence of gene recombination and mutation. Analysis of the genomic genetic composition can be used to infer the genetic evolutionary relationships between species.

Organization and expression analysis of 5S and 45S ribosomal DNA clusters in autotetraploid Carassius auratus

open access: yesBMC Ecology and Evolution, 2021
Background Autotetraploid Carassius auratus (4n = 200, RRRR) (abbreviated as 4nRR) is derived from whole genome duplication of Carassius auratus red var. (2n = 100, RR) (abbreviated as RCC).

Establishment of a hybrid lineage via Megalobrama amblycephala (♀) × Culter alburnus (♂) and Genetic Analysis

open access: yesAquaculture Reports
Distant hybridization is a significant method for creating new hybrid lineages and potentially hybrid species. In the past ten years, we have established a hybrid lineage population, BTF1-BTF6 (six generations), via crosses between Megalobrama ...

Chromatin-mediated mechanisms of hybrid fertility in F1 male hybrids of Culter alburnus and Megalobrama amblycephala

open access: yesBMC Biology
Background Interspecific hybridization is a fundamental evolutionary process, yet it often results in male sterility due to genomic incompatibilities and disrupted epigenetic regulation.

Application of Flow Cytometry to Determine Cell DNA Content in the Genetic Breeding of Fish

open access: yesFishes
In the field of fish genetic breeding, accurately determining the DNA content and ploidy of fish is of great significance. This article introduces the use of flow cytometry (FCM) to measure the DNA content and conduct ploidy analysis by sampling ...

Full-Length Transcriptome Reveals Heterologous Sperm Fragments in Natural Gynogenetic Grass Carp

open access: yesFishes
Grass carp (Ctenopharyngodon idella) is one of the most economically important cyprinid species cultured in China. The diploid gynogenetic grass carp (2nGGC, 2n = 48) was generated from the hybrid of female grass carp (GC, 2n = 48) and male topmouth ...

The ecology of polyploid establishment and exclusion, with implications for polyploid biogeography

open access: yesNew Phytologist
Summary The relationship between polyploid formation, triploid fitness and plant reproduction has been studied for over a century, and uniparental reproduction has long been recognized to play a crucial role in polyploid establishment.

Establishment and Biological Characteristics Analysis of a Hybrid Culter Lineage from Megalobrama amblycephala (♀) and Culter alburnus (♂)

open access: yesAnimals
Culter alburnus (topmouth culter, TC) is extensively distributed in various rivers and lakes in China. As a widely adaptive fish species, they have significant economic value and special ecological roles.

Research on the Mechanism of Hypoxia Tolerance of a Hybrid Fish Using Transcriptomics and Metabolomics

open access: yesBiology
The novel hybrid fish BTB, derived from crossing blunt snout bream (Megalobrama amblycephala, BSB) and topmouth culter (Culter alburnus, TC), exhibits markedly hypoxia tolerance in aquaculture. In this study, hypoxic treatment experiments confirmed that,
