| 摘 要： | 肌纤维是构成肌肉的基本单位,肌纤维的特性直接影响猪肉品质.猪的肌纤维根据肌球蛋白重链(MyHC)的多态性可分为1、2a、2b和2x 4种类型,在代谢上分别与慢速氧化型、快速氧化型、快速酵解型和中间类型相对应.肌纤维的生成在分子水平上受到肌细胞生成素基因的精确调控,肌纤维的类型在生长过程中不断发生转化,并受遗传、生长、性别和营养等多因素的影响.

| Abstract: | Muscle fiber was basic unit for constructing muscle and muscle fiber characteristics had direct impacts on pork quality.According to polymorphism of myosin heavy chain(MyHC),porcine muscle fibers were divided into four types:1,2a,2b and 2x,and they were corresponded to the slow-oxidative type,fast-oxidative type,fast glycolytic type and the intermediate type by the metabolism.The generation of muscle fiber was regulated exactly by the myogenin gene on the molecular level.The muscle fiber type converted in t... |
