UAS regulatory sequences drive expression of a short hairpin dsRNA (shRNA) targeting tsu.
ovary, with Scer\GAL4nanos.PG
ovary, with Scer\GAL4NP1624
Flies expressing tsudsRNA.shRNA.Scer\UAS in either the ovarian germline (under the control of Scer\GAL4nos.PG) or the somatic cells (Scer\GAL4tj-NP1624) have small ovaries compared to controls.
