UASt regulatory sequences drive expression of an inverted repeat.
Expression under the control of Scer\GAL4pnr-MD237 results in external sensory organs consisting of empty or multiple sockets in 20-30% of the Scer\GAL4pnr-MD237 expression domain of the notum.
Expression under the control of Scer\GAL4pnr-MD237 results in bristle morphology defects on the notum in 70-80% 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.
