UASt regulatory sequences drive expression of an E(spl)m8-HLH cDNA carrying a deletion of the WRPW motif.
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).
