The en repressor domain has been substituted for nucleotides 1624-2259 of lz.
lethal - all die before end of pupal stage, with Scer\GAL4lz-gal4
some die during pupal stage, with Scer\GAL4lz-gal4
ommatidium, with Scer\GAL4lz-gal4
Flies expressing lzenR.Scer\UAS under the control of Scer\GAL4lz-gal4 that survive to late pupal stages have glazed eyes in which individual ommatidia cannot be observed.
