我们报告了第一个完整的实验室大鼠遗传连锁图谱的构建。通过对1171个简单序列长度多态性(slps)的检测,我们鉴定出432个在SHR和BN大鼠株之间显示多态性的标记,并将它们定位在一个(SHR × BN) F-2杂交中。这些位点定义了21个大的连锁组,与21条大鼠染色体相对应,以及9号染色体附近的一对标记,这些标记与地图的其余部分没有联系。由于99.5%的标记属于21个大连锁组中的一个,这些图谱似乎覆盖了绝大多数的大鼠基因组。该图谱的可用性应该有助于对与哺乳动物生理和病理生物学相关的定性和定量性状的基因进行全基因组扫描。
We report the construction of the first complete genetic linkage map of the laboratory rat. By testing 1171 simple sequence length polymorphisms (SSLPs), we have identified 432 markers that show polymorphisms between the SHR and BN rat strains and mapped them in a single (SHR x BN) F-2 intercross. The loci define 21 large linkage groups corresponding to the 21 rat chromosomes, together with a pair of nearby markers on chromosome 9 that are not linked to the rest of the map. Because 99.5% of the markers fall into one of the 21 large linkage groups, the maps appear to cover the vast majority of the rat genome. The availability of the map should facilitate whole genome scans for genes underlying qualitative and quantitative traits relevant to mammalian physiology and pathobiology.
