UASt regulatory sequences drive expression of an E(spl)m8-HLH cDNA carrying a deletion of helix III and IV.
Scer\GAL4sca-537.4-mediated expression has no effect on the development of bristles on the head, notum or abdomen. Does not modify the number of ectopic scutellar macrochaetes of strain ZB1.4 (activator insertion Scer\GAL4455.2 is combined with l(1)scScer\UAS.cHa).
