In a Brown Leghorn chicken strain, four endogenous proviral loci have been identified. The DNA mapping data show strong homology between their structures and that of the Rous-associated virus O (RAV-O) genome. Two of them seem similar to ev3 and ev6 loci previously described in White Leghorn chickens; the two others are unknown in White Leghorns. Using DNA amplification methods, envelope genes of these endogenous viral structures have been partially sequenced. The results demonstrate that subgroup-specific sequences of the endogenous loci were largely homologous with those of RAV-O.
在一个褐壳蛋鸡品系中，已鉴定出四个内源性前病毒位点。DNA图谱数据显示，它们的结构与劳斯相关病毒O（RAV - O）基因组的结构具有很强的同源性。其中两个似乎与先前在白来航鸡中描述的ev3和ev6位点相似；另外两个在白来航鸡中是未知的。使用DNA扩增方法，已对这些内源性病毒结构的包膜基因进行了部分测序。结果表明，内源性位点的亚组特异性序列与RAV - O的亚组特异性序列在很大程度上是同源的。
