畜禽遗传资源保护方法的研究进展

Research Progress on Protection Methods of Livestock and Poultry Genetic Resource

畜禽遗传资源作为生物多样性的重要组成部分,正面临着严峻的考验,对其开展保护工作是一项迫在眉睫更是必须持之以恒的任务。作者对目前畜禽遗传资源保护的主要方法和技术,包括活体保护及利用冷冻技术、基因文库技术、体细胞克隆技术和分子遗传标记等技术保护,特别是对近年新发展起来的诱导多功能干细胞(induced pluripotent stem cells,iPSCs)技术在畜禽遗传资源保护方面的应用作了概述,以期进一步对畜禽遗传资源保护奠定基础。

Livestock and poultry genetic resource, which is the crucial part of biodiversity,is facing a severe test. The conser vation work is no mere an extremely urgent task,but rather a necessarily persevering mission. Several main preservation meth- ods and technologies,including in vivo preservation as well as technologies of cryopreservation,gene library, somatic cell clo- ning,molecular genetic markers. In particular, the induced pluripotent stem cells（iPSCs）technology developed in recent years are summarized in this paper to lay the foundation of further conservation.
