摘要
生长激素受体(growth hormone receptor,GHR)基因是家畜生产力的重要候选基因,并成为提高反刍动物奶肉产量等研究的焦点。近年来,有关牛羊GHR基因的研究不断增加,该领域的深入探讨可能产生家畜育种和生产中候选基因研究的突破性进展,而且有助于标记辅助选择的实施.本文主要就牛羊GHR的结构和功能区域的分析,及其基因的结构和表达调控,多态性与生产性能的相关研究等方面进行了综述和讨论。
GHR gene is an attractive candidate gene for animal productivity and has been a focus of research aiming at increasing meat and milk production of ruminants. Recently, more studies have been conducted in cattle, sheep and goats on GHR gene, the further research could lead to the break through of candidate gene search in animal breeding and production, and pave the way toward the marker assistant selection. This article describes the structure and functional region of GHR, the research in gene structure and expression, and the association of GHR gene polymorphisms with production traits of cattle, sheep and goats.
