UASt regulatory sequences drive expression of an inverted repeat.
Expression under the control of Scer\GAL4pnr-MD237 results in bristle morphology defects on the notum in 40-50% of the Scer\GAL4pnr-MD237 expression domain.
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.
