Abstract

This paper reports the isolation and characterization of twoHindIII repetitive DNA families from the genome of two lacertid lizards,Podarcis sicula andLacerta 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 theHindIII DNA family isolated fromP. 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.
