This paper reports the isolation and characterization of two HindIII repetitive DNA families from the genome of two lacertid lizards, Podarcis sicula and Lacerta saxicola. These satellites did not appear to be related to each other. The consensus sequences of their monomeric units did not show any similarity, though both DNAs were A-T rich. Moreover, each of them was found only in closely related species. The monomeric unit of the HindIII DNA family isolated from P. sicula (pLHS) showed a close resemblance to pLCS, a centromeric satellite DNA previously isolated from the same species; it was, however, mainly localized at pericentromeric, interstitial and telomeric levels. The results also provide interesting information on the systematics of the lacertids studied.
本文报道了从两种蜥蜴（意大利壁蜥和岩蜥）的基因组中分离和鉴定出两个HindIII重复DNA家族。这些卫星序列似乎彼此无关。它们单体单元的共有序列没有显示出任何相似性，尽管两种DNA都富含A-T。此外，它们各自仅在亲缘关系较近的物种中被发现。从意大利壁蜥中分离出的HindIII DNA家族（pLHS）的单体单元与pLCS（先前从同一物种中分离出的着丝粒卫星DNA）非常相似；然而，它主要定位于着丝粒周围、间质和端粒水平。研究结果还为所研究的蜥蜴类的系统学提供了有趣的信息。
