Abstract

A new class of moderately repetitive elements, designated the pDv sequences of Drosophila virilis, was cloned and molecularly analysed. The pDv elements occupy about 200 sites in the D. virilis genome. Their number decreases in related species with increasing phylogenetic distance. The pDv elements are characterized by a rather stable localization within the D. virilis genome, by intensive transcription and by partial polytenization in salivary gland chromosomes. Furthermore, they are capable of transposition in interspecific hybrids. DNA sequence analysis revealed that the pDv element contains tandemly arranged 36 bp repeat units which are flanked by imperfect direct terminal repeats of about 80 bp and inverted terminal repeats of 4 bp.
