【目的】探讨甘肃截形叶螨Tetranychus truncatus种群遗传多样性、遗传分化及种群系统发育关系。【方法】本研究以2016年6-9月采自甘肃省8个不同生境的34个截形叶螨种群的518头螨样品进行mtDNA COI基因PCR扩增、测序，并利用MEGA7.0和Dna SP5.0等软件分析截形叶螨不同种群的mtDNA COI基因序列变异和遗传分化情况。【结果】在34个截形叶螨地理种群中共获得...
mtDNA稀有变异或是精神分裂症一种病因
mtDNA稀有变异 精神分裂症
2016/8/4
近日，中国科学院昆明动物研究所研究员姚永刚、博士生毕蕊与中南大学湘雅二医院陈晓岗团队合作，对11个展现出母系遗传特征的精神分裂症家系进行了研究，通过测定各家系中先证者的mtDNA全基因组序列发现，mtDNA稀有致病变异可能是精神分裂症发病的一种病因，但其低频异质性很可能与精神分裂症不相关。相关结果近期分别发表于《精神分裂症的研究》 和《分子神经生物学》期刊。
