UASt regulatory sequences drive expression of an inverted repeat.
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 100% of the Scer\GAL4pnr-MD237 expression domain, depending on the insertion line used.
Expression under the control of Scer\GAL4pnr-MD237 results in bristle morphology defects on the notum in 0% or 30-40% of the Scer\GAL4pnr-MD237 expression domain, depending on the insertion line used.
