UASp regulatory sequences drive expression of an artificial microRNA (shRNA) targeting piwi.
female sterile, with Scer\GAL4VP16.nanos.UTR, Scer\GAL4VP16.otu, Scer\GAL4nanos.PG
When tested in females, expression of piwidsRNA.shRNA.Scer\UAS.P\T under the control of all three of the drivers Scer\GAL4otu.T:Hsim\VP16, Scer\GAL4nos.PG and Scer\GAL4nos.UTR.T:Hsim\VP16 results in sterility.
