The identification of causative mutations affecting economically important traits has benefited the worldwide pig industry. We investigated the genetic variation at five loci including RYR1, IGF2, FUT...
Prolactin and Growth Hormone in Birds:Protein Structure,Gene Structure and Genetic Variation
glycosylation growth hormone prolactin variation
2009/7/29
Prolactin (PRL) and Growth hormone (GH) are secreted from the anterior pituitary gland and affect a wide variety of physiological functions in birds. A causal relationship between plasma PRL concentra...
摘要应用RAPD技术分析了梅山猪、淮南猪、通城猪、八眉猪、合作猪、大白猪的遗传变异。用276个随机引物对6个猪种混合DNA扩增筛选,24个引物产生多态性。此24个引物经重新优化反应条件体系后,对276个个体DNA进行扩增。结果6个猪种的遗传多样性指数分别为0.178672、0.17781、0.15995、0.14549、0.16949和0.14157,群体内平均遗传多样性指数为0.16216,总群...

摘要采用13号染色体上与K88ab和K88ac受体基因连锁的2对引物(S0223和S0068),研究沙子岭猪和大约克猪的遗传差异性。结果表明,2个猪种在2个基因座均存在多态性,其基因杂合度和Shannon信息指数存在很大差异,而中外猪种的K88ab和K88ac受体基因也存在遗传差异,这2对引物可望作为K88ab和K88ac受体基因的遗传标记。Abstract: The genetic variat...
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,...
