V200D
V200D amino acid change thought to be responsible for mutant phenotype. soD also contains an amino acid replacement G66A that is not reponsible for the phenotype.
lethal (with Df(2R)BSC264)
so[D] adults lack eyes.
soD/+ animals completely lack compound eyes.
soD/+ mutants are eyeless or have severely reduced eyes. The more copies of the allele present in the fly, the more severe the eye phenotype is. The eye primordia of soD mutants displays normal specification and maintenance, but eye discs become arrested at the time of neuronal morphogenesis and relatively late stages of eye development are affected.
Heterozygotes lack compound eyes and the region normally occupied by the eye is replaced by a large nonpigmented and nondifferentiated field of tissue. Heterozygotes show a complete lack of photoreceptor differentiation during larval eye disc development.
Heterozygotes exhibit an extreme eyeless phenotype, this can be rescued by heat induced expression of so (repetitive heat shocks during third instar).
Heterozygotes display an extreme reduction in eye size.
RK1 Heterozygote has small, glazed eyes.

nej3/+ ; soD/+ adults lack eyes and the nondifferentiated field of tissue that is seen in place of the eye in soD/+ single mutants is replaced by head tissue in the double mutant adults. nej3/+ ; soD/+ eye imaginal discs are small and undergo increased levels of cell death. Expression of nejScer\UAS.T:SV5\V5 under the control of Scer\GAL4ey.PH suppresses the no-eye phenotype of soD/+; eye imaginal discs are nearly normal in size and contain large numbers of photoreceptor cell clusters, and in adults, the eyes are fully pigmented, although they are not normally patterned. Expression of nejΔBHQ.Scer\UAS under the control of Scer\GAL4ey.PH suppresses the no-eye phenotype of soD/+, to the same degree as expression of nejScer\UAS.T:SV5\V5 under the control of Scer\GAL4ey.PH. Expression of nejΔNZK.Scer\UAS or nejΔQ.Scer\UAS under the control of Scer\GAL4unspecified does not suppress the no-eye phenotype of soD/+.
