Evolution and Dynamics of Small RNA Response to a Retroelement Invasion in Drosophila
Journal: Molecular Biology and Evolution
Year: 2012

Although small RNAs efficiently control transposition activity of most transposons in the host genome, such an immune system is not always applicable against a new transposon's invasions. Here, we explored a possibility to introduce potentially mobile copy of the Penelope retroelement previously implicated in hybrid dysgenesis syndrome in Drosophila virilis into the genomes of two distant Drosophila species. The consequences of such introduction were monitored at different phases after experimen
