UASt regulatory sequences drive expression of an inverted repeat.
Expression under the control of Scer\GAL4pnr-MD237 results in loss of bristles on the notum in 40-50% or 80-90% 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 10-20% or 60-70% of the Scer\GAL4pnr-MD237 expression domain, depending on the insertion line used.
