Specific genetic interference with behavioral rhythms in Drosophila by expression of inverted repeats.
We describe a new experimental technique that allows for a tissue-specific reduction of gene activity in the Drosophila nervous system. On the basis of the observation that certain gene functions can be ubiquitously blocked by injecting double-stranded RNA into Drosophila embryos, we employed a method to interfere with an individual gene function permanently in a predetermined cell type. This was achieved by the formation of an inverted-repeat RNA sequence in the tissue of interest under control of the GAL4/UAS binary expression system. As an example, we show that inverted-repeat-mediated interference with the period gene produces a hypomorphic period phenotype. A selective decrease of period RNA appears to be a component of the cellular response.
