中国科学院昆明动物所等开发完成犬类SNP数据库DoGSD
中国科学院昆明动物所 犬 数据库
2014/11/27
家犬作为人类生活和工作中的伙伴,其进化研究一直是遗传学研究中的一个热点。然而目前使用的家犬参考SNP数据集,不仅数量少,采样地不够广泛,而且测序覆盖度差异大,SNP数据主要只来源于两个品种的两个犬只,并不利于家犬的群体遗传研究。
温带竹子支系(the temperate bamboo clade)包括23-32属,约600种,分布于东亚地区(特别是喜马拉雅)、东南亚部分地区、印度南部和斯里兰卡、非洲和马达加斯加以及北美洲东部的温带低海拔地区和热带或亚热带高山。东亚有该支系约500种,是其多样化中心,其中中国西南特有种就有约180种。温带竹子支系在分子系统学研究中被证明是一个单系类群,但类群内部之间的关系尚未得到很好的澄清。...
