UASt regulatory sequences drive expression of an inverted repeat.
Depending on the insertion line used, expression under the control of Scer\GAL4Mef2.PR can result in flightless flies.
Expression under the control of Scer\GAL4Mef2.PR results in grossly normal adult indirect flight muscles.
Expression under the control of Scer\GAL4Mef2.PR results in morphologically wild-type myofibrils in the adult indirect flight muscles.
Expression under the control of Scer\GAL4Mef2.PR results in wild-type sarcomeres in the adult indirect flight muscles.
Expression under the control of Scer\GAL4pnr-MD237 results in a colour difference between the central Scer\GAL4pnr-MD237 expression domain of the notum and the surrounding lateral region in 0% or 50-60% of the Scer\GAL4pnr-MD237 expression domain, depending on the insertion line used.
