Larval muscle 4 neuromuscular junctions in wgl-8 heterozygotes do not show significant changes in synaptic bouton number, as compared to controls.
wgl-8 heterozygosity does not significantly affect the mitotic index in the adult midgut epithelium, as compared to controls.
wgl-8 embryos show segment polarity phenotype and no naked cuticle between denticle belts on the ventral epidermis (resulting in a lawn of denticles).
All epidermal cells secrete denticles in the mutant embryo.
wgl-8 mutant embryos have no second midgut constriction.
Embryos completely lack segment polarity and have a lawn of uniform, large, thick denticles covering the ventral epidermis. The embryos are much smaller than wild type. They are usually closed dorsally. There are only 8 rows of ventral epidermal cells per segment in wgl-8 embryos (wild-type number is, on average, 12 rows per segment). The cells are larger than normal and are cuboidal. Cells in the ventral epidermis enter mitosis 16 in mutant embryos (as occurs in wild type) and mitotic figures are as readily apparent in the ventral epidermis in stage 12 mutant embryos as they are in wild-type embryos.
Patterning defects evident in the denticle belts. Many mutant embryos are dorsally closed but exhibit severe defects in dorsal patterning, with loss of dorsal hairs and the presence of abnormal cuticular structures. A proportion show a mild dorsal-open phenotype. Leading edge cells never elongate along the DV axis, instead they stretch along the AP axis. Certain lateral cells contract like leading edge cells, stretching along the AP axis.
Posterior cells of each segment are transformed to anterior fates in homozygous embryos and secrete denticles. Most of the denticles of these embryos resemble the large type found in normal row 5. Denticle orientation is often reversed or aligned towards the ventral midline.
Homozygous embryos lack RP2 neurons.
Embryos are shorter than wild-type and secrete only denticles with no naked cuticle. wgl-8 embryos expressing armS10.Scer\UAS.T:Hsap\MYC (using Scer\GAL4e22c) produce a cuticle phenotype similar to embryos expressing armS10.Scer\UAS.T:Hsap\MYC (using Scer\GAL4e22c) in a wild-type background; nearly all secreted cuticle is naked. wgl-8 embryos expressing armΔN.Scer\UAS (using Scer\GAL4e22c) secrete naked cuticle interspersed with denticles on their ventral surface, while the dorsal surface is unchanged from the wgl-8 mutant phenotype.
Only one central invagination fold of the stomodeal invagination is observed.
Embryos exhibit a lawn of denticle belts.
Defective in gonad assembly.
Mutant embryos have a lawn of row-5-type ventral denticles, with segmental polarity reversals.
hh expression in the embryo begins to fade as the germ band reaches full extension, though it does persist in a few midline cells which may be neuroblasts.
Before stage 10 wg embryos have normal hh expression, but it begins to decay at stage 10 and is gone by stage 11.
Very strong segment polarity phenotype.
The RP2 neuron is the only identifiable cell altered. The restricted phenotype may be due to improper communication between neurons.
Embryos lack head cuticle and there are no or very rudimentary filzkorper. Embryos show an aberrant pattern of cell death and lack of parasegmental and segmental boundaries.

wgl-8 heterozygosity does not suppress the increased mitotic index in the adult midgut epithelium induced by the adulthood-only expression of UvragHMS01357 under the control of Scer\GAL4esg-NP5130 (and Gal80[ts], for the temporal control of expression).
The segment polarity phenotype and the lack of naked cuticle between denticle belts on the ventral epidermis characteristic for zygotically mutant wgl-8 embryos is not modified by Scer\GAL4arm.PU-driven expression of either sggScer\UAS.T:Ivir\HA1 or sggKK-MI.Scer\UAS.T:Myr-Src64B,T:Ivir\HA1.
The naked cuticle phenotype (loss of denticle belts on the ventral epidermis) observed in embryos expressing sggScer\UAS.T:Myr-Src64B,T:Ivir\HA1 under the control of Scer\GAL4arm.PU is not affected by combination with wgl-8 homozygosity (which on its own leads to loss of naked cuticle and ectopic denticles).
he increase in average cell number in the stalks between egg chambers which is seen in Mmp2Y53N/Df(2R)BSC132 females after being shifted to the restrictive temperature is dominantly suppressed if the females also carry a single copy of wgl-8.
ovosvb-108/Y ; wgl-8/+ larvae raised at 25[o]C have significantly fewer quaternary trichomes compared to controls.
Loss of the second midgut constriction in wgl-8 mutant embryos is suppressed by CbydsRNA.cTa. Loss of the first midgut constriction in CbydsRNA.cTa injected embryos is partially suppressed by wgl-8.
Addition of W05014 or Df(3L)H99 does not result in any pronounced improvement of the wgl-8 segment polarity defect; all cells still secrete a uniform lawn of denticles and the cuticle remains smaller than wild type in double mutant embryos. However, the number of denticles is more than doubled in wgl-8 ; Df(3L)H99 embryos compared to wgl-8 single mutants, and the denticles secreted by the double mutants are much smaller than in wgl-8 single mutants. The effect of a reduction in W+ dose on wgl-8 is additive The number of rows of ventral epidermis cells is increased to 12-14 per segment in wgl-8 ; Df(3L)H99 embryos and the cells are much smaller than in wgl-8 single mutants. Most of the cells are cuboidal, they create a pattern of block-like pseudosegments and all cells secrete denticles in the double mutant embryos.
wgl-8,pucA251.1F3 double mutants show a novel loss of dorsal cuticle phenotype. Dorsal closure is never initiated. Lateral epidermal cells elongate along the AP axis and resemble leading edge cells. Massive cell degeneration is seen in the lateral and dorsal epidermis of late embryos.
Wings on wgl-8/+; dally06464/dally06464 animals show a stronger wing notch phenotype than dally06464/dally06464 alone at a higher penetrance (3% to 8%).
