微卫星PCR产物变性与非变性PAGE-银染检测方法的比较The Comparision of Denatured and non-denatured PAGE–Silver- Staining Detection of PCR Product of Microsatellites
微卫星 PAGE PCR 银染
2008/1/8
摘要
用鸡的微卫星引物对6个中国地方鸡种的两个微卫星位点进行PCR扩增。将扩增产物在变性与非变性聚丙烯酰胺凝胶（PAGE）上进行电泳，经银染，表明微卫星产物在二者上的电泳结果有明显的差异。在非变性聚丙烯酰胺凝胶中，表现为有较多的非特异带，而在变性胶中微卫星扩增产物条带清晰，易于鉴定。Abstract：The genomic DNAs from six chicken breeds in Chin...
中外11个猪种A-FABP基因微卫星遗传变异的研究Genetic Variation of A-FABP Microsatellites in Eleven Pig Breeds

摘要
利用微卫星技术对五指山猪、沂蒙黑猪、汉江黑猪、莱芜猪、北京黑猪、民猪、成华猪、内江猪、二花脸猪、巴马香猪和大白猪11个猪种共420头猪的脂肪细胞脂肪酸结合蛋白基因内含子的微卫星序列的遗传变异进行了研究。研究表明：（1）中国猪种在A-FABP基因微卫星基因座上有极高的的多态性，五指山猪的PIC最高（PIC=0.7904）并检测到11个等位基因，但北京黑猪仅检测到两个等位基因。（2）本实验中，...
栓皮栎天然群体SSR遗传多样性研究Genetic Diversity of Microsatellites（SSRs）of Natural Populations of Quercus variabilis
栓皮栎 微卫星(SSR) 遗传多样性 遗传分化
2008/1/8
摘要
利用微卫星(SSR)标记对我国4个省内的5个栓皮栎（Quercus variabilis Bl.）天然群体的遗传多样性进行了研究。16对SSR标记揭示了栓皮栎丰富的遗传多样性：等位基因数（A）平均8.4375个，有效等位基因数(Ne)平均为5.9512个，平均期望杂合度(He)0.8059，Nei多样性指数(h)为0.8041。栓皮栎自然分布区中心地带的群体具有较高的遗传多样性，而人为对森...
摘要微卫星序列广泛存在于各类真核生物基因组中，一般为散在分布的中等程度重复序列。不同物种中，微卫星序列的含量以及占优势的微卫星序列类型各不相同。复制时,微卫星序列易于发生长度突变，这种突变与微卫星序列的复制滑移有关，同时也受多种因素的影响。微卫星序列可能是原微卫星序列通过复制滑移使序列长度扩增形成的。进化过程中，微卫星序列的长度变化维持在一定的范围内。由于微卫星标记多态性高、重复性好，并且操作简单...
摘要
利用4个微卫星标记（OarFCB11，OarAE101，McM218，McM38）对波尔山羊、太行山羊和河北奶山羊的等位基因频率、群体多态信息含量、有效等位基因数、杂合度和遗传距离进行了遗传检测，并测定了波尔山羊与河北奶山羊及太行山羊的杂交效果。结果表明：4个微卫星标记在波尔山羊、太行山羊和河北奶山羊3个品种中存在多态性，可以用于山羊遗传多样性的评估；从不同品种来看，太行山羊的遗传变异程度...
