Detailed Description

Follicle cells in pucA251.1F3 clones show no consistent defect in mitotic cycles between stages 1-6 in oogenesis. However the nuclei in pucA251.1F3 mutant cells remain small, suggesting that these follicle cells do not enter endocycles at the mitotic-to-endocycle transition.

Mothers with germlines homozygous for pucA251.1F3 lay reduced numbers of eggs; these eggs are small relative to wild type. Resulting pucA251.1F3 maternal/zygotic embryos have severe defects in embryonic development and secrete only fragmented scraps of cuticle. The epithelial cells of these embryos undergo an increase in apoptosis in a segmentally repeated pattern in both the ventral and lateral epidermis. The cuticle defects are suppressed in embryos with a paternal wild-type copy of puc, but this fails to rescue embryonic lethality. pucA251.1F3 maternal-only embryos display patterning defects, exhibiting segmental deletions and fusions and a corresponding loss of denticle belts.

pucA251.1F3 mutant clones cannot be recovered in the wing disc.

The eye tissue of pucA251.1F3 homozygous flies is almost completely missing.

In contrast to wild-type flies, pucA251.1F3/+ flies do not die in response to being fed with paraquat. pucA251.1F3/+ males show significant extension of mean and maximal lifespan when compared to wild-type flies. Females show qualitatively similar lifespan data, although the extension of lifespan is less pronounced than in males. pucA251.1F3/+ flies contain significantly decreased levels of oxidized proteins compared to wild-type flies.

Females containing homozygous clones produce small, unfertilised eggs with aberrant eggshells 48 hours after clone induction. The eggshells are open in the anterior, with inadequate sealing between the operculum and the collar and the dorsal appendages are shorter than normal and variable in width. Egg chambers containing chorion encased small eggs have a mass of nurse cells similar in size to stage 11 nurse cells, indicating that nurse cell dumping is not completed. Eggs derived from females containing homozygous germline clones have normal eggshells and are fertilised. Homozygous anterior follicle cell clones are associated with defects in dorsal appendage formation. At late stages aberrant cell shapes and defects in epithelial continuity are seen in main body follicle cell clones. This class includes flaccid cup-shaped eggs that are likely resorbed and not laid.

Embryos show puckering of dorsal epidermis with loss of dorsal hair identity and a naked scar at the dorsal midline. Ventrally, denticle belts are narrowed, with the narrowing most pronounced at the ventral midline.

Genetic Interactions
Statement
Reference

The rough eye phenotype observed in adults expressing MagiScer\UAS.T:Avic\GFP under the control of Scer\GAL4GMR.PU is not modified by combination with single copy of pucA251.1F3.

pucA251.1F3 dominantly suppresses the wing notching phenotype seen in Df(1)N-54l9 heterozygotes (the penetrance of the phenotype is significantly decreased in the double heterozygotes).

Male and female flies homozygous (or hemizygous) for pcm5 and heterozygous for pucA251.1F3 are viable, but over half show a bald patch at the anterior end of the dorsal midline at 19[o]C, indicating that thorax closure is not quite complete. At 25[o]C the majority of flies have bald patches.

Male and female flies homozygous (or hemizygous) for pcm5 and heterozygous for pucA251.1F3 have dull wings at 19[o]C and 25[o]C.

The flw1/Y ; pucA251.1F3/+ combination is viable. 30% of these flies have wing phenotypes that range from slight defects in the posterior part of the wing to stumps. Flies with the most severe wing phenotypes sometimes have third leg malformations.

Pp1-87B87Bg-3 does not show any discernible mutant phenotype with pucA251.1F3.

The wing defects seen in flw1/Y ; pucA251.1F3/+ flies are suppressed to wild type by bsk1/+, zip1/+ or sqhE20.E21.

The wing defects seen in flw1/Y ; pucA251.1F3/+ flies are not suppressed by sqhA20.A21.T:Zzzz\FLAG.

Heterozygosity for bsk2 partially rescues pucA251.1F3 mutant eye tissue.

arm3,pucA251.1F3, pan2,pucA251.1F3, wgPE4,pucA251.1F3 and wgl-8,pucA251.1F3 double mutants all show a novel loss of dorsal cuticle phenotype.

Dominantly partially suppresses the dorsal open phenotype of hep1 hemizygous embryos.

Xenogenetic Interactions
Statement
Reference

Expression of BacA\p35Scer\UAS.cHa, driven by Scer\GAL4en-e16E, in a pucA251.1F3/+ background causes tissue overgrowth throughout the posterior compartment of the wing disc in >90% of flies. Disrupted foci within the disc contain excess cells, resulting in abnormal folding of the disc epithelium. Most cells within these foci are not apoptotic. Some discs show extensive areas of overgrowth. In adults, overgrowths in the interior of the wing resemble wing blisters; excess cells appear to be in one compartment as overgrowths project from either the dorsal or the ventral surfaces. When overgrowths arise along the wing margin, excess tissue is readily apparent as an extension of the wing. Similar but less frequent outgrowths occur in posterior regions of adult legs.

Complementation and Rescue Data
Partially rescued by
Comments

Expression of pucScer\UAS.P\T.T:Hsap\MYC at the time of clone induction (driven by Scer\GAL4Act5C.PI) rescues pucA251.1F3 cell viability in the wing disc, although fewer pucA251.1F3 clones are recovered compared to wild-type clones.
