UASt regulatory sequences drive expression of sens containing the amino acid replacement K509R.
visible, with Scer\GAL4sca-109-68
scutellar bristle | ectopic, with Scer\GAL4sca-109-68
Expression of sensK509R.Scer\UAS under the control of Scer\GAL4sca-109-68 results in ectopic scutellar bristles (although less than induced by sensScer\UAS.cPa under the same conditions).
