Comparative transcriptomic analysis of reproductive characteristics of reciprocal hybrid lineages derived from hybridization between Megalobrama amblycephala and Culter alburnus.

ABSTRACT:

Background

Distant hybridization is an important breeding technique for creating new strains with superior traits by integrating two different genomes. Successful hybridization of Megalobrama amblycephala (Blunt snout bream, BSB, 2n = 48) and Culter alburnus (Topmouth culter, TC, 2n = 48) was achieved to establish hybrid lineages (BT and TB), which provide valuable materials for exploring the mechanisms of distant hybridization fertility. In this study, the gonadal tissue transcriptomes of BSB, TC, BT-F₁, and TB-F₁ were sequenced using Illumina high-throughput sequencing technology to analyze the reproductive characteristics of BT and TB.

Results

Differential gene expression analysis showed that the differentially expressed genes in BT vs BSB and BT vs
