Overall length of the tracheal dorsal trunk is normal in pkpk-sple-13/pkeq stage 16 embryos.
Homozygous adults show defects in ommatidial patterning, with ommatidia having random orientation and chirality.
Homozygous clones in the pupal wing (23 hours after puparium formation) do not affect polarity of trichomes in surrounding wild-type tissue.
pkpk-sple-13 somatic clones in the adult abdomen have disturbed polarity - usually a 'whorl' of hairs. This effect is cell autonomous.
Mutant animals display a planar cell polarity eye phenotype: misrotations and random chirality with an associated loss of the mirror symmetry line, the equator, at the dorsoventral midline. Chirality defects appear to be associated with a mutant R4 precursor.
57.8% of ommatidia in pkpk-sple-13/pksple-1 mutant somatic clones in the eye are normal. 0.6% have rotated ommatidia, 41.6% have chirality defects, none are achiral (0% unscorable). 53.0% of ommatidia in homozygous mutant somatic clones in the eye are normal. 4.6% have rotated ommatidia, 41.9% have chirality defects, 0.5% are achiral (0% unscorable).
85% of homozygous somatic clones in the wing exhibit cell autonomy, though about 15% display a clear domineering non-autonomy. This is not restricted to large or early induced clones.
Causes no embryonic phenotype even when homozygous mutant embryos develop from homozygous mutant mothers. Has a weak polarity phenotype in the wing, notum, abdomen, eye and legs. In the wing, shows a slight effect on triple-row bristle orientation and gently curved hair polarity vectors. In the eye a mixture of chiral forms of ommatidia are seen. Some ommatidia fail to rotate properly, resulting in imperfections in the hexagonal stacking and a slightly rough eye phenotype. Some ommatidia are aligned at 60o to the equator and some show anterior-posterior axis reversals. The T3 and T4 segments carry medial duplications of the proximal and distal joint structures, with the middle of each segment deleted. This results in alternating reversed-proximal and reversed-distal tarsal joint structures with half the length of a normal segment. T5 is unaffected. Denticle belt morphology and denticle orientation remains wild-type. Wings in pkpk-sple-13/pk30 flies show a phenotype stronger than pkpk-sple-13/pkpk-sple-13 and weaker than pk30/pk30.

Vangstbm-6, dgo380, pkpk-sple-13 and dsh3, Vangstbm-6, dgo380, pkpk-sple-13 triple and quadruple heterozygotes exhibit mild wing trichome orientation defects in proximal regions.
Flies expressing Mks1GD9100 under the control of Scer\GAL4en-e16E in a pkpk-sple-13/+ genetic background display wild-type wing hair polarity.
Flies expressing CG15283GD13108 under the control of Scer\GAL4en-e16E in a pkpk-sple-13/+ genetic background display wild-type wing hair polarity.
pkpk-sple-13/+ suppresses the ommatidial over-rotation phenotype which is caused by expression of nmoScer\UAS.cUa under the control of Scer\GAL4hs.2sev.
The ommatidial rotation defects observed in ecspok hemizygous adult eyes are not suppressed by pkpk-sple-13/+.
pkpk-sple-13 fz21/fz21 clones in the pupal wing (32 hours after puparium formation) cause neighbouring cells to point their trichomes towards the clone, as occurs with fz21/fz21 single mutant clones in the pupal wing.
pkpk-sple-13 Vangstbm-6/Vangstbm-6 clones in the pupal wing (32 hours after puparium formation) cause neighbouring cells to point their trichomes away from the clone, as occurs with Vangstbm-6/Vangstbm-6 single mutant clones in the pupal wing.
dgo380 pkpk-sple-13/pkpk-sple-13 clones in the pupal wing (32 hours after puparium formation) do not affect polarity of trichomes in surrounding wild-type tissue.
The planar polarity phenotype in the abdomen of fz21/fz21 flies is largely unaffected when the whole animal is pkpk-sple-13/pkpk-sple-13.
When fzScer\UAS.cZa; Scer\GAL4hh-Gal4 flies are pkpk-sple-13 homozygous, the zone of repolarisation straddling the anterior-posterior compartment boundaries in adult abdominal segements is enlarged, but otherwise unchanged.
The addition of dshhs.PA to pkpk-sple-13 animals has no effect on the pkpk-sple-13 wing hair polarity phenotype.
Completely suppresses the wing phenotypes (thickened veins and wing-edge loss) of Nnd-3 flies.
Does not alter the eye tissue polarity phenotype produced by fzScer\UAS.cAa expressed under the control of Scer\GAL4hs.2sev.

pkAct5C.pk can rescue the wing planar polarity defects seen in pkpk-sple-13 homozygotes. Expression at 16 and 20 hours after puparium formation (APF) results in only negligible polarity defects in the rescued wings, and expression at 24 and 28 hours APF provides partial rescue.
pksev.sple.PS rescues the ommatidial polarity defects of pkpk-sple-13 homozygotes.
Clones expressing fzScer\UAS.T:Avic\GFP-EGFP under the control of Scer\GAL4Act5C.PI in a pkpk-sple-13/pkpk-sple-13 background result in non-clonal cells pointing their trichomes away from the clone. This effect extends 8-9 cells from the clone boundary. This effect is still seen if the clones are also mutant for dgo380, but in this case the effect only extends 5-6 cells from the clone boundary.
