摘要: 牛肉品质作为消费者决策与产业经济效益的核心要素,决定了肉类产品的市场竞争力与养殖经济回报,其表型特征包括大理石花纹、嫩度、多汁性、风味及色泽等感官与理化指标,并受遗传基础、营养代谢、饲养管理及环境因素等多维度交互调控。传统评价方法主要依赖感官评分与理化测定,虽可反映部分肉质差异,但难以在分子层面系统解析其复杂形成机制,因而制约了肉质的遗传改良与精准调控。近年来,随着基因组学、转录组学、蛋白质组学和代谢组学等组学技术的迅速发展,为在全基因组尺度上系统解析牛肉品质关键性状的调控基因、通路及生物标志物提供了新工具,显著深化了对肉品质形成机制的理解。作者在系统梳理牛肉品质影响因素的基础上,重点围绕肌内脂肪沉积、肉嫩度和风味等核心性状,分析其主要调控通路与潜在分子标志物,并总结当前多组学整合研究的技术路径与关键成果,进一步探讨现有研究在样本异质性、组学解读深度及功能验证等方面的局限,旨在为牛肉品质的精准评价、分子育种策略制定及加工调控优化提供理论依据与参考。

Abstract: Beef quality,as a key determinant of consumer decision-making and industrial economic efficiency,directly affects the market competitiveness of meat products and the economic returns of livestock production.Its phenotypic traits include both sensory and physicochemical attributes,such as marbling,tenderness,juiciness,flavor,and color,and are jointly regulated by genetic background,nutritional metabolism,feeding practices,and environmental factors.Conventional evaluation methods,which mainly depend on sensory scoring and physicochemical measurements,can capture certain differences in meat quality but fall short in revealing the underlying molecular mechanisms,thus hindering genetic improvement and precise quality control.In recent years,the rapid advancement of omics technologies—including genomics,transcriptomics,proteomics,and metabolomics—have provided powerful tools to comprehensively identify regulatory genes,pathways,and biomarkers associated with key beef quality traits,thereby enhancing our understanding of the molecular basis of meat quality formation.This review systematically examines the factors affecting beef quality,with a particular focus on core traits such as intramuscular fat deposition,tenderness,and flavor,and further analyzes their major regulatory pathways and potential molecular biomarkers.It further summarizes the methodologies and major findings of current multi-omics integration studies,while critically addressing the limitations related to sample heterogeneity,insufficient omics interpretability,and a lack of functional validation.The goal is to provide a theoretical framework and practical reference for accurate beef quality assessment,molecular breeding strategy development,and optimization of post-harvest processing.

Key words: beef quality; molecular regulatory mechanisms; multi-omics integration; intramuscular fat deposition; meat tenderness; flavor compounds
