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.

福建麻鸭遗传结构分析及与肌肉生长相关的重要基因鉴定

福建麻鸭是福建省著名的肉用水禽，具有肉产量高、繁殖潜力大、抗逆性强等特点。为了充分发掘这些优势的遗传特性，研究人员利用福建黑鸭和福建白鸭进行了全基因组重测序和转录组分析。种群结构分析表明，这两个羽毛品系之间存在明显差异。同源性分析结果表明，黑羽品系受人工影响较大，ROH岛基因明显富集于肌肉组织相关术语和通路中。选择性扫描和转录组分析显示，与肌肉组织和肌肉纤维相关的术语和通路的基因显著富集。所发现的关键候选基因，如 MEF2C、MYOZ2 和 METTL21C，被认为在福建麻鸭的产肉过程中发挥着关键作用。本研究为提高福建麻鸭的产肉性能提供了一个新的视角，有利于育种策略和生产管理。

期刊介绍： First self-published in 1921, Poultry Science is an internationally renowned monthly journal, known as the authoritative source for a broad range of poultry information and high-caliber research. The journal plays a pivotal role in the dissemination of preeminent poultry-related knowledge across all disciplines. As of January 2020, Poultry Science will become an Open Access journal with no subscription charges, meaning authors who publish here can make their research immediately, permanently, and freely accessible worldwide while retaining copyright to their work. Papers submitted for publication after October 1, 2019 will be published as Open Access papers. An international journal, Poultry Science publishes original papers, research notes, symposium papers, and reviews of basic science as applied to poultry. This authoritative source of poultry information is consistently ranked by ISI Impact Factor as one of the top 10 agriculture, dairy and animal science journals to deliver high-caliber research. Currently it is the highest-ranked (by Impact Factor and Eigenfactor) journal dedicated to publishing poultry research. Subject areas include breeding, genetics, education, production, management, environment, health, behavior, welfare, immunology, molecular biology, metabolism, nutrition, physiology, reproduction, processing, and products.
