BglI-MboII 541bp fragment including the entire Ggal\Cash4 coding region is subcloned into "pUAST".
macrochaeta & scutellum, with Scer\GAL4455.2
Scer\GAL4455.2-mediated expression in the D.melanogaster scutellar primordia allows the development of numerous ectopic bristles. Phenotype is indistinguishable from that obtained by Scer\GAL4455.2-mediated expression of l(1)scScer\UAS.cHa or scScer\UAS.cHa.
Df(1)sc10-1 flies lack all sensory bristles, Scer\GAL4455.2-mediated expression of Ggal\Cash4Scer\UAS.cHa in the scutellar primordia induces ectopic scutellar bristles.
