摘　　要：肌内脂肪(IMF)含量是评价肉品质的重要因素,对风味、嫩度、纹理等肉类感官品质起着重要作用,而IMF的沉积主要受脂肪摄取、合成、分解3条代谢途径的调控。本文综述了影响IMF沉积的相关候选基因,初步揭示了影响脂肪代谢的机理,旨在为今后调控IMF沉积的相关研究提供理论依据。Intramuscular fat （IMF） content is an important factor in the evaluation of meat quality, which plays important roles in flavor, tenderness and texture of meat sensory quality, however, the regulation of intramus- cular fat deposition is mainly affected by three metabolic pathways, namely, fat uptake, synthesis and decom- position. This paper reviewed the related candidate genes of intramuscular fat deposition, preliminarily revea- ling the influence mechanism of fat metabolism, so as to provide a theoretical basis for further study of the reg- ulation of intramuscular fat deposition.
