贵州东北部黑叶猴种群mtDNA D-loop序列多态性
黑叶猴 线粒体控制区 单倍型 遗传多样性
2016/7/18
贵州东北部作为黑叶猴在中国的主要分布区之一，黑叶猴的数量在近 30 年急剧下降，栖息地破碎化严重，保护形势不容乐观。深入了解黑叶猴在贵州东北部地区地理种群的分子变异及遗传水平现状，可以为黑叶猴保护提供重要的依据。本文以黑叶猴的粪便、毛发为实验材料，利用线粒体DNA分子标记，对采自贵州东北部地区黑叶猴野生种群79个粪便样品和黔灵公园笼养种群22个粪便样品、5份毛发样品的线粒体控制区(mtDNA D-...

GenBank中mtDNA全基因组数据在重新分析和挖掘时需要核查
GenBank mtDNA全基因组
2009/12/15
线粒体含有自身的遗传物质，在人类的生命活动中扮演着重要的角色。对mtDNA全基因组测定分析已成为医学、分子人类学及法医学研究中的重要手段。目前全球已有6700多个个体的mtDNA全基因组序列得到测定，相关的数据保存在公共数据库如GenBank中，可供研究者进行重新分析和挖掘。由于各种原因，某些测定的mtDNA全序列数据存在不同程度的错误，后续的分析工作如果没能充分剔除这些错误，而仅对数据库中现有...
线粒体DNA（mtDNA多态性在动物保护生物学中的应用
线粒体DNA 动物保护生物学 进化显著单位 管理单位
2009/9/9
本文从两个方面论述了mtDNA在动物保护生物学中的应用：一是对物种进行遗传多样性的检 测与管理，二是进行与种群统计学数据相关的遗传分析。前者与保护的长期效益（如进化） 密切相关，而后者则主要用于指导短期管理措施的制定。同时，本文重点论述了mtDNA在进 化显著单位(ESUs)和管理单位(MUs)的认定方面的作用。认定ESUs的目的是隔离管理遗传多 样性，它是一系列系统进化史独特的种群，这种独特性同...
