We created transgenic strains of Drosophila melanogaster in which the rrf-1 or ego-1 RdRp genes from C. elegans were placed under the control of the yeast GAL4 upstream activation sequence. Activation of the gene was performed by crossing these lines to flies carrying the GAL4 transgene under the control of various Drosophila enhancers. RT-PCR confirmed the successful expression of each RdRp gene. The resulting phenotypes indicated that introduction of the RdRp genes had no effect on D. melanogaster morphological development.Keywords: Caenorhabditis elegans protein; EGO 1 protein, C elegans; EGO-1 protein, C elegans; helminth DNA; recombinant protein; RNA directed RNA polymerase; animal; article; Caenorhabditis elegans; Drosophila melanogaster; enzymology; female; gene; gene expression MicroRNAs (miRNAs); RNA interference (RNAi); RNA-directed RNA polymerase (RdRp)201010.1007/s11248-010-9372-y2016-02-24
