dSTIM regulates mechanosensory bristle differentiation. Dorsal view of the adult wild-type (wt) notum (A), showing the position and orientation of single michrochaete (mC) and macrochaete (MC) mechanosensory bristles. Flies expressing dSTIMRNAi driven by pnr.Gal4 exhibit a partially bald cuticle lacking mC over the pannier expression domain (dotted ring) (B), while flies overexpressing dSTIMFL exhibit misorientated and duplicated bristles when induced by pnr.Gal4 (C), or sca..Gal4 (inset C).
