P{PZ} insertion in the vicinity of the presumptive transcription initiation site.
edlJV/Df(2R)edl-L19 is an enhancer of eye photoreceptor cell phenotype of spiSCP1
edlJV/Df(2R)edl-L19 is an enhancer of eye photoreceptor cell phenotype of S218
The loss of photoreceptor neurons seen in S218/+ animals is enhanced by edlJV/Df(2R)edl-L19; in the double mutant animals, 65% of ommatidia lack at least one photoreceptor neuron. The loss of photoreceptor neurons seen in spiSCP1/spiSCP1 animals is enhanced by edlJV/Df(2R)edl-L19.
Excision of the P{PZ} element can revert the lethal phenotype.
