UASt regulatory sequences drive expression of an inverted repeat.
lethal - all die during embryonic stage, with Scer\GAL4btl.PS
tracheal branch primordium, with Scer\GAL4btl.PS
Expression of wrm1KK107175 under the control of Scer\GAL4btl.PS leads to an elongated tracheal network and gas filling failure of tracheal tubes in embryos.
