Detailed Description
Statement
Reference

wghs.2sev eyes are rough.

wghs.2sev animals have a rough eye.

wghs.2sev flies have a rough eye phenotype.

Expression of one copy of the wghs.2sev transgene causes a rough eye phenotype.

Mutants exhibit a rough eye phenotype.

Flies carrying a single copy of wghs.2sev have smaller, narrower eyes than wild type. The regular hexagonal array of the ommatidia is disturbed and all interommatidial bristles are lost (sockets as well as bristles are missing). Ommatidia are also missing, mostly in anterior-dorsal regions of the eye. Misoriented ommatidia and ommatidia with missing photoreceptor cells are seen. There is an excess of pigment granules and there are up to four additional secondary pigment cells per ommatidium.

Flies lack interommatidial bristles and have a dosage-sensitive rough eye phenotype.

Additional Comments
Genetic Interactions
Statement
Reference

wghs.2sev rough eyes are suppressed when ecaKK109376 or Snx3KK109353 or CHOp24KK107384 is expressed using both Scer\GAL4ey.PU and Scer\GAL4GMR.PU.

Heterozygosity for trbdDelta or panunspecified suppresses the rough eye phenotype of wghs.2sev flies.

Mosaic animals in which most cells in the eye have a srt1 or a srt2 genotype show a significant reversion of the rough eye phenotype seen when following expression of the wghs.2sev transgene.

The wghs.2sev phenotype is strongly enhanced by svspa-pol and suppressed by svsev.PB.
