Abstract

Fujian Muscovy duck is a well-known meat waterfowl in Fujian Province due to its high meat production, superior breeding potential, and strong resistance. To fully explore the genetic characteristics of these advantages, Fujian black Muscovy duck and white Muscovy duck were used for whole-genome re-sequencing and transcriptome analyses. Population structure analysis showed significant differentiation between the two feather strains. Runs of homozygosity analysis indicated a stronger artificial influence on the black-feathered strain, with ROH island genes notably enriched in muscle tissue-related terms and pathways. Selective sweep and transcriptome analysis revealed a significant enrichment of genes linked to muscle tissue and muscle fiber-related terms and pathways. Key candidate genes identified, such as MEF2C, MYOZ2, and METTL21C, are believed to play crucial roles in meat production in Fujian Muscovy duck. This study offers a new perspective on improving meat production in Fujian Muscovy duck, which can benefit breeding strategies and production management.

摘要

福建番鸭因其高产肉量、卓越的繁殖潜力和强大的抵抗力，是福建省著名的肉用型水禽。为了充分探究这些优势的遗传特征，利用福建黑番鸭和白番鸭进行全基因组重测序和转录组分析。群体结构分析表明这两个羽色品系之间存在显著分化。纯合子片段分析表明黑羽品系受到更强的人工选择影响，其纯合子片段岛基因显著富集于肌肉组织相关的术语和通路。选择性清除分析和转录组分析揭示，与肌肉组织和肌纤维相关的术语和通路中相关基因显著富集。鉴定出的关键候选基因，如MEF2C、MYOZ2和METTL21C，被认为在福建番鸭的肉生产中发挥关键作用。本研究为提高福建番鸭的肉产量提供了新视角，有助于育种策略和生产管理。
