畜禽种质资源保护与利用科技创新团队
研究方向
1、畜禽遗传资源收集、多维保护
广泛收集国内、国外(巴基斯坦、尼泊尔、孟加拉等畜禽资源丰富的国家)畜禽遗传资源,尤其是特有、珍稀和具潜在利用功能的畜禽资源,构建畜禽资源血液、组织和DNA的样本库,对遗传资源进行表型、分子水平等评价,筛选有重要、潜在引进价值的遗传资源;建立世界规模最大的畜禽遗传资源体细胞库,共计8万余份,覆盖了我国120个重要、濒危品种,开展畜禽遗传资源的细胞保存。
2、畜禽遗传资源保存新技术研究
研究各类细胞的低温耐受性以及低温损伤机制和预防措施,以期寻找减轻细胞损伤的技术,提高低温保存效果,以保证动物资源长久保存。建立主要畜禽遗传资源共96种类型干细胞的建系、鉴定、保存与诱导技术体系,共计1万余份。
3、畜禽遗传资源系统评价和特色畜禽基因资源挖掘
对特殊生态地区的畜禽遗传资源(猪、绵羊、山羊等)开展抗逆、抗病、优良性状等方面基因资源挖掘,精准解析畜禽适应性状的遗传机制,为优异基因资源的广泛利用奠定基础。鉴定与发掘家畜生长发育、抗逆等特性的新候选基因30余个,包括家养动物的高海拔低氧适应性和体尺大小南北差异等。
