Mendelian segregation analysis was used to define genetic loci for the induction of infectious xenotropic murine leukemia virus in several laboratory and wild-derived mice. MA/My mice contain two loci for xenotropic virus inducibility, one of which, Bxv -1, is the only induction locus carried by five other inbred strains. The second, novel MA/My locus, designated Mxv -1, is unlinked to Bxv -1 and shows a lower efficiency of virus induction. The NZB mouse carries two induction loci; both are distinct from Bxv -1 since neither is linked to the Pep-3 locus on chromosome 1. Finally, one partially inbred strain derived from the wild Japanese mouse, Mus musculus molossinus, carries multiple (at least three) unlinked loci for induction of xenotropic virus. Although it is probable that inbred strains inherited xenotropic virus inducibility from Japanese mice, our data suggest that none of the induction loci carried by this particular M. m. molossinus strain are allelic with Bxv -1.
孟德尔分离分析用于确定几种实验室小鼠和野生来源小鼠中诱导感染性嗜异性小鼠白血病病毒的基因座。MA/My小鼠含有两个嗜异性病毒诱导基因座,其中一个Bxv-1是其他五个近交系携带的唯一诱导基因座。第二个新的MA/My基因座,命名为Mxv-1,与Bxv-1不连锁,且病毒诱导效率较低。NZB小鼠携带两个诱导基因座;两者均与Bxv-1不同,因为它们都不与1号染色体上的Pep-3基因座连锁。最后,一种源自野生日本小鼠小家鼠的部分近交系携带多个(至少三个)不连锁的嗜异性病毒诱导基因座。虽然近交系很可能从日本小鼠继承了嗜异性病毒诱导能力,但我们的数据表明,这种特定的小家鼠品系携带的诱导基因座与Bxv-1均无等位关系。
