Detailed Description
Statement
Reference

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.

Additional Comments
Genetic Interactions
Statement
Reference

Presence of sty226/+ suppresses pupal lethality in Scer\GAL4how-24B>SmndsRNA.C.Scer\UAS.WIZ flies and partially suppresses pupal lethality in Scer\GAL4how-24B>SmndsRNA.N.Scer\UAS.WIZ flies.

The presence of a sty226 background significantly enhances ectopic wing vein formation found in cswY279C.Scer\UAS (Scer\GAL4tub) mutants.

A sty226 background enhances the cswY279C.Scer\UAS (Scer\GAL4tub) rough eye phenotype, with the number of R7 in each ommatidium increasing.

The addition of sty226/+ enhances the eye cell polarity phenotype seen in fz19/fz20 animals. Heterozygotes suppress the ommatidial polarity defects seen in Ras64BV14.Act5C.
