The complete E(spl)m4-BFM cDNA is under the control of UASt sequences.
dorsal row & sensory mother cell, with Scer\GAL4ap-md544
No extra neuroblasts are seen when E(spl)m4-BFMScer\UAS.cAa is expressed under the control of Scer\GAL4wor.PA or Scer\GAL4elav.PU.
Expression of m4Scer\UAS.cAa under the control of Scer\GAL4ey.PB has no effect on either eye or antenna disc development.
Expression of m4Scer\UAS.cAa when driven by Scer\GAL4bi-omb-Gal4 in the wing disc leads to an increase in the numbers of sensory organ precursors seen.
Flies with m4Scer\UAS.cAa under the control of Scer\GAL4ptc-559.1, Scer\GAL4sca-T3, Scer\GAL4455.2, Scer\GAL4pnr-MD237 or Scer\GAL4ap-md544, show duplications of sensillum campaniformium, macrochaetae and microchaetae in their normal locations that are frequently tufted together. No effects are seen in the wing. Flies with m4Scer\UAS.cAa under the control of Scer\GAL4ptc-559.1, show duplications of the scutellar bristles and the anterior cross-vein campaniform sensilla in their normal locations. If two copies of m4Scer\UAS.cAa are present the number of bristles increases yet more. Flies with m4Scer\UAS.cAa under the control of Scer\GAL4455.2, show duplications of the scutellar bristles. Flies with m4Scer\UAS.cAa under the control of Scer\GAL432B or Scer\GAL4bi-md653 showed no wing pattern aberrations. m4Scer\UAS.cAa, when driven by Scer\GAL4ap-md544, creates clusters of wing margin sensory organ precursors (SOPs) in their normal locations in the dorsal row, where there would only be single SOPs in wild-type. Over commitment of the ACV and L3 precursors of campaniform sensilla are also seen. The N/numb mediated asymmetric divisions in the SOP lineage are not affected. In somatic clones where m4Scer\UAS.cAa is over-expressed under the control of Scer\GAL4Ubx.PdC, clustered microchaetae are seen, even at the clone boundary, suggesting the effect is acting at the level of signal reception.

mαScer\UAS.cAa enhances the number of extra scutellar bristles caused by expression of m4Scer\UAS.cAa under the control of Scer\GAL4ptc-559.1 m4Scer\UAS.cAa driven by Scer\GAL4ptc-559.1 cannot restore scutellar bristles to E(spl)Scer\UAS.cLa, HLHm7Scer\UAS.cdCa, HLHmδScer\UAS.cdCa or HLHmβScer\UAS.cdCa The scutellar bristle duplication phenotype caused by expression of m4Scer\UAS.cAa under the control of Scer\GAL4455.2 can be suppressed by a single copy of HLHm7Scer\UAS.cdCa. m4Scer\UAS.cAa, when driven by Scer\GAL4ap-md544 in a Df(1)sc10-1 background, does not restore any chaetae lost in this deficiency. The presence of NAx-1 partially suppresses the supernumerary scutellar bristle phenotype seen in m4Scer\UAS.cAa when driven by Scer\GAL4455.2. The presence of H2 partially suppresses the supernumerary scutellar bristle phenotype seen in m4Scer\UAS.cAa when driven by Scer\GAL4ptc-559.1. The presence of Df(3R)Dl-BX6, neurA101, bib2 or mami511 has no significant effect on the supernumerary scutellar bristle phenotype seen in m4Scer\UAS.cAa when driven by Scer\GAL4ptc-559.1.
