【摘要】：近年来,高通量测序技术的规模化应用及生物信息技术的普及,极大地推动了家畜基因组学的发展,实现了分子育种标记全基因组水平的快速、精准定位,为全基因组选择育种奠定了重要基础。数千年来的驯化和选择,形成了用途多样的山羊品种,如乳用、皮用、绒用及肉用等,为人类提供了丰富的生产和生活资料。国内外学者采用高通量测序技术对山羊的遗传多样性及生产性能的遗传机制进行了研究,以期找到与山羊种质特性相关的基因,从而为山羊的遗传改良提供新的标记。作者对近五年来基于高通量测序技术研究山羊的遗传多样性和产绒、产奶、繁殖等生产性状的研究进展进行了综述,以期为评估山羊优良种质特性和与生产性状相关的优异基因定位的工作提供参考。
[Abstract]:In recent years, the large-scale application of high-throughput sequencing technology and the popularization of biological information technology have greatly promoted the development of livestock genomics, and realized the rapid and accurate localization of molecular breeding markers at the whole genome level.It lays an important foundation for whole genome selection breeding.Thousands of years of domestication and selection have resulted in a variety of goat breeds, such as milk, leather, velvet and meat, which provide abundant production and living materials for human beings.High throughput sequencing technique was used to study the genetic mechanism of goat genetic diversity and performance in order to find the genes related to goat germplasm characteristics and to provide a new marker for goat genetic improvement.In this paper, the authors reviewed the research progress of goat genetic diversity, cashmere production, milk production and reproduction based on high-throughput sequencing in recent five years.This study was intended to provide a reference for the evaluation of goat excellent germplasm characteristics and the mapping of excellent genes related to production traits.
