Abstract

Transpositions of the gypsy retrotransposon in the Drosophila melanogaster genome are controlled by the flamenco locus, which is represented as an accumulation of defective copies of transposable elements. In the present work, genetic control by the flamenco locus of the transcriptional and transpositional activities of the Tirant retrotransposon from the gypsy group was studied. Tissue-specific expression of Tirant was detected in the tissues of ovaries in a strain mutant for the flamenco locus. Tirant was found to be transpositionally active in isogenic D. melanogaster strains mutant for the flamenco locus. The sites of two new insertions have been localized by the method of subtractive hybridization. It has been concluded from the results obtained that the flamenco locus is involved in the genetic control of Tirant transpositions.
