Abstract
Transposons are genetic elements that use various mechanisms of transposition to move around the genome, thus posing a risk to genomic integrity. Repression of transposable elements (TEs) involves the complex PIWI pathway and several proteins associated with heterochromatinization. All players of TE repression are indispensable for proper reproductive fitness, as loss-of-function mutations in these genes result primarily in sterility and impaired reproductive development. When investigating the function of novel genes with similar phenotypes, elevated transposon expression in reproductive tissues can be a marker for involvement in the aforementioned processes. Here, we present a protocol for investigating TE levels in adult Drosophila ovaries, from dissection to data analysis.
