Application of bovine microsatellite markers on Saola (Pseudoryx nghetinhensis)

The aim of the present study was to assess the applicability of bovine microsatellite markers on Saola (Pseudoryx nghetinhensis). A total of 127 microsatellite markers were tested on a male and a young female Saola. An efficient amplification was observed for 123 markers (96.8%), 73 markers (59.3%) were polymorphic. Four loci (BM2304, BMS1928, BMS779 and ILSTS006) on cattle chromosomes 1, 4, 7 and 8, respectively, failed to amplify in Saola. Two cattle Y‐chromosome‐specific microsatellite markers (INRA126 and BM861) were successfully amplified from both sexes in Saola. However, two additional markers (INRA124 and INRA189) on Y‐chromosome failed to amplify in the female animal. These results show that most of the bovine microsatellite markers are applicable in Saola and therefore they can be used to study the phylogenetic relationships and the genetic diversity of the Saola population.     

犬微卫星DNA遗传标记及其在犬繁育中的应用

遗传标记是指可追踪染色体、染色体某一节段、某个基因座在家系中传递的任何一种遗传特性。它具有两个基本特征,一是可遗传性,二是可识别性。因此,生物的任何有差异的突变型均可作为遗传标记。遗传标记主要包括形态标记、细胞学标记、生化标记和DNA分子标记四类,本文对犬微卫星     

四川常羽乌骨鸡群体遗传多样性分析

利用选自家禽基因组的10个微卫星标记,对四川常羽乌骨鸡5个群体(四川山地乌骨鸡白羽系、黑羽系;黄忠山地乌骨鸡;黄忠山地乌骨鸡绿壳蛋系;草科乌骨鸡)的遗传多样性进行了检测,计算了各群体的群体杂合度、群体间遗传距离,并根据遗传距离进行了聚类分析。结果表明所选择的微卫星标记在各群体中表现出较高的多态性;四川5个乌骨鸡群体遗传多样性比较丰富,群体平均杂合度为0.5383到0.6659;各群体间的遗传距离有一定的差异;聚类分析将5个群体聚为三类。     

Application of bovine microsatellite markers for genetic diversity analysis of European bison (Bison bonasus)

In this study, the cross‐amplification of a commercial multiplex set of 11 cattle (Bos taurus) microsatellites was tested on a panel of 35 European bison (Bison bonasus) individuals. After polymerase chain reaction optimization, all loci cross‐amplified successfully in investigated bisons. Number of alleles and observed and expected heterozygosity per locus are in the range of 2–4, 0.086–0.629 and 0.288–0.621 respectively. The availability of a heterologous set of multiplexed microsatellite markers derived from cattle opens an avenue for collecting profound genetic data for efficient conservation management strategies of the European bison.
