摘要
羊肉具有高蛋白、低脂肪、肉质细嫩和风味独特等特点,深受广大消费者喜爱.绵羊的肉质性状受品种、营养、环境、屠宰后加工等多种因素影响,调控机制复杂,传统的肉质评定方法难以阐明肉品质变化的潜在机制和途径.在后基因组时代,基因组、转录组、蛋白质组、微生物组和代谢组等组学技术凭借高通量、高灵敏度和系统性等优势,已成为畜禽肉质性状研究的有力工具,能从分子层面深入研究生物特性形成的根源.本文基于公开发表的文献,重点综述了组学技术及多组学联用方法在绵羊肉质性状中的应用进展,并对其应用的挑战和前景进行了展望,以期为绵羊肉质性状的机理解析提供方法,为绵羊分子育种提供思路.
Abstract
Sheep meat is increasingly popular among consumers because of its high protein,low fat,tender texture,and unique flavor.Sheep meat quality is influenced by various factors such as breed,nutrition,environment,and post-slaughter processing,which result in complex regulatory mechanisms.However,conventional meat quality assessment methods are difficult to elucidate the potential mechanisms and pathways for quality variations.In the post-genomic era,omics technologies such as genomics,transcriptomics,proteomics,metagenomics,and metabolomics offer advantages of high throughput,high sensitivity,and systematic.These omics technologies act as effective tools for in-depth molecular-level investigation of the underlying mechanisms behind the formation of biological traits in livestock and poultry breeding research.Based on the published literature,this review summarizes the progress of omics technologies and multi-omics joint analysis in the study of sheep meat quality traits,along with a perspective into the current challenges and prospects of their application,aiming to provide methods for understanding the complex biological process and offer perspectives for molecular breeding in sheep.
