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 or adult/pharate lethality.
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 bristle morphology defects on the notum in 20-30% or 30-40% of the Scer\GAL4pnr-MD237 expression domain, depending on the insertion line used.
Expression under the control of Scer\GAL4pnr-MD237 results in the absence of 20-30% of the Scer\GAL4pnr-MD237-expressing area of the notum.
