Nucleotide substitution: C2055T.
|Phenotype Manifest In|
Escapers of lethality show a disorganized eye phenotype. Majority of ommatidia have extra R7 cells, generated by transformation of cone cells. Some of the extra photoreceptors resemble outer (R1-R6) photoreceptor neurons. Mystery cells assume R3/R4 fates. In heterozygous condition, 1-7% of ommatidia show an extra R7 cell or an occasional gain or loss of an outer photoreceptor cell.
Pupal lethal when hemizygous. The number of tracheal branches emanating from the dorsal and ganglionic branches is higher than normal in homozygous embryos.
|Phenotype Manifest In|
sty[+]/sty226 is an enhancer of wing vein | ectopic phenotype of Scer\GAL4tub.PU, cswN308D.Scer\UAS.P\T
sty226/Scer\GAL4tub.PU is an enhancer of ommatidium phenotype of Scer\GAL4tub.PU, cswY279C.Scer\UAS.P\T
sty226/Scer\GAL4tub.PU is an enhancer of photoreceptor cell R7 | ectopic phenotype of Scer\GAL4tub.PU, cswY279C.Scer\UAS.P\T
sty226/Scer\GAL4tub.PU is an enhancer of wing vein phenotype of Scer\GAL4tub.PU, cswY279C.Scer\UAS.P\T
sty226 is a suppressor of eye phenotype of HScer\UAS.cMa/HScer\UAS.cMa, Scer\GAL4GMR.PF/Scer\GAL4GMR.PF
The presence of a sty background significantly enhances ectopic wing vein formation found in csw[Y279C.Scer\UAS] (Scer\GAL4[tub]) mutants. A sty background enhances the csw[Y279C.Scer\UAS] (Scer\GAL4[tub]) rough eye phenotype, with the number of R7 in each ommatidium increasing.
