Reference

fz19/fz19 disrupted planar polarity is observable as aberrant orientation of ommatidia and wing hairs, compared to wild type controls. fz19/fz21 disrupted planar polarity is observable as the disrupted orientation of ommatidia, compared to wild type controls.

Homozygous fz19 mutants are viable but exhibit planar polarity defects.

Mutant adults have an average of 2.0 +/- 0.2 extra tarsal joints in the leg compared to wild type.

Approximately 16% of ommatidia are symmetrical in fz19/fz21 flies.

fz20/fz19 flies show defects in ommatidial polarity.

In the eyes of fz19/fz20 transheterozygotes, 10% of ommatidia are mispolarized.

fz19 has a moderate multiple wing hair phenotype in combination with fz30.

fz19/fz20 animals exhibit a weak eye phenotype - 9% of ommatidia show polarity defects.

Mutants show no significant disruption of ovarian morphology.

84.8% of ommatidia in fz19/fz20 mutant somatic clones in the eye are normal. 6.3% have rotated ommatidia, 6.1% have chirality defects, 2.5% are achiral (0.3% unscorable).

Mutant animals have a mutant planar cell polarity phenotype.

Autonomous phenotype in wing clones.

Moderate thoracic bristle phenotype; moderate wing-hair disorientation.

Flies double mutant for otkA1/otkA1; fz19/fz19 are viable but exhibit planar polarity defects.

Flies double mutant for otk2C26/otk2C26; fz19/fz19 are viable but exhibit planar polarity defects.

Flies double mutant for Df(2R)D72/+; fz19/fz19 are viable but exhibit planar polarity defects. Flies mutant for Df(2R)D72/Df(2R)D72; fz19/+ are viable and do not exhibit planar polarity defects. Flies double mutant for Df(2R)D72/Df(2R)D72; fz19/fz19 are lethal.

fz19 fz2C1 double homozygous clones in the wing result in wing margin defects.

ed1X5 dominantly enhances the phenotype of mis-rotation of ommatidia that is seen in fz19/fz20 animals, without affecting the chirality phenotype.

The symmetrical ommatidium phenotype seen in fz19/fz21 flies is suppressed by Egfrtop-18A/+.

Homozygosity for bdg164 enhances the ommatidial polarity defects caused by fz20/fz19.

The ommatidial polarity defects seen in bdgGMREP homozygotes are not-suppressed by fz19.

The ommatidial polarity defects of fz19/fz20 mutants are enhanced in a dsh1/+, dco5B2.6/+, dcoj3B9/+, dco2/+ and dco3/+ backgrounds. In each double mutant background, the percentage of mispolarized ommatidia are increased.

Embryos that lack zygotic fz and fz2 function which are derived from fz19/fzGL31 fz2e2 females mated to fzGL31 fz2e2/+ males are modestly shortened and have mild patterning defects in the cuticle.

The addition of dsh1/+ strongly enhances the eye cell polarity phenotype seen in fz19/fz20 animals. The addition of argos5F4/+ , argosΔ7/+, argosA254Δ15/+, or argosrlt/+ , enhances the eye cell polarity phenotype seen in fz19/fz20 animals. The addition of styF7/+, styX3J3/+, styX3F7/+, styΔ5/+, or sty226/+ , enhances the eye cell polarity phenotype seen in fz19/fz20 animals. The addition of Ras85D2F4/+ enhances the eye cell polarity phenotype seen in fz19/fz20 animals.
