UASt regulatory sequences drive expression of a full-length Mmus\Atoh7 cDNA.
Mmus\Atoh7UAS.cSa/Scer\GAL47 is a suppressor of ommatidium phenotype of ato1
Mmus\Atoh7UAS.cSa/Scer\GAL47 is a non-suppressor of interommatidial bristle phenotype of ato1
Expression of Mmus\Atoh7Scer\UAS.cSa under the control of Scer\GAL47 in ato1 flies rescues only a small number of ommatidia (less than 25 per eye) and none of these contain photoreceptor cells with clear R8 cell morphology. Interommatidial bristles are not produced in these flies.
