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.

(Kramer et al., 1999)

Pupal lethal when hemizygous. The number of tracheal branches emanating from the dorsal and ganglionic branches is higher than normal in homozygous embryos.

Reference

sty^F7 is an enhancer of ommatidium phenotype of fz²⁰/fz¹⁹

Suppressor of

Statement

Reference

sty^F7 is a suppressor of ommatidium phenotype of Ras64B^V14.Act5C

(Strutt and Strutt, 2003)

Additional Comments

Genetic Interactions

Statement

Reference

The addition of sty^F7/+ enhances the eye cell polarity phenotype seen in fz¹⁹/fz²⁰ animals. Heterozygotes suppress the ommatidial polarity defects seen in Ras64B^V14.Act5C.

(Strutt and Strutt, 2003)

The extra R7 cells of sty^F7 are suppressed in ommatidia also mutant for Ras85D^N17.hs.2sev.
