Description

Imprecise excision of the progenitor insertion, resulting in a deletion of approximately 29kb that removes the CG15561 transcription unit and all of the ASPP coding sequence.

Detailed Description
Statement
Reference

ASPPd/ASPP8 transheterozygotes exhibit significantly more inter-ommatidial cells and frequently misplaced bristles in the pupal eye, as compared to controls; adults show larger wings and frequent duplication of scutellar bristles.

Mutant adults are 6.1% heavier than controls.

Homozygous flies have an enlarged, rough eye phenotype compared to controls. There is disorganisation of the ommatidial lattice, with missing or extra interommatidial bristle cells. Clustering of the bristle cells is often seen and the bristle cells frequently contact four or more cells (wild-type bristle cells contact three neighbours). The mutant ommatidia often have five vertices, instead of six (as occurs in wild type).

There is no increase in the number of cells per ommatidium in the pupal retina of ASPP8 animals, but adult eyes have significantly more ommatidia (796 +/- 24 per eye) compared to controls (747 +/- 25 per eye).

Mutant adults have enlarged wings (on average 11.8% larger than normal). The density of wing hairs in the mutant wing is comparable to that of controls, indicating that the increase in wing size is due to an increase in the number of cells rather than an increase in cell size.

Homozygous clones do not have any apparent growth advantage over control clones.

Additional Comments
Genetic Interactions
Statement
Reference

ASPPd/ASPP8, Cskj1D8/+ adults very frequently show wing notches, which are never observed in controls; this phenotype is fully rescued by ASPPUbi-p63E.GFP, but only partially by ASPPFA.Ubi-p63E.GFP.

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 ASPP8.

ASPP8/ASPP8 Cskj1D8/+ adults show a notched wing phenotype. Wing discs of ASPP8/ASPP8 Cskj1D8/+ third instar larvae show considerable apoptosis. Neither phenotype is seen in ASPP8/ASPP8 or Cskj1D8/+ single mutants.

Btk29Ak00206/+ largely suppresses the ectopic apoptosis in wing discs and notched wing phenotype seen in ASPP8/ASPP8 Cskj1D8/+ animals.

The eye phenotype of ASPP8 homozygotes is suppressed by Btk29Ak00206/+ and by Src64Bko/Src64Bko.

The ectopic apoptosis seen in the wing discs of pucE69/+ Cskj1D8/+ double heterozygotes is enhanced if they are also heterozygous for ASPP8, resulting in adults with a severely reduced wing size. These adults also have leg deformities.

The wing discs of ASPP8/ASPP8 pucE69/+ third instar larvae show a moderate ectopic patch of apoptotic cells. Adults of this genotype do not show wing notching.

ASPP8/ASPP8 dramatically enhances the delamination, movement and apoptosis phenotype seen in Csk mutant cells which are at the boundary between mutant and wild-type cells in wing discs expressing CskIR.Scer\UAS under the control of Scer\GAL4ptc-559.1.

Comments

ASPPd/ASPP8 transheterozygotes show increased numbers of inter-ommatidial cells and misplaced bristles in the pupal eye, as well as the enlarged wings in adults, all of which are fully rescued by ASPPUbi-p63E.GFP but only partially rescued by ASPPFA.Ubi-p63E.GFP, ASPPKVK.Ubi-p63E.GFP, ASPPFA-WK.Ubi-p63E.GFP, or ASPPWK.Ubi-p63E.GFP. ASPPd/ASPP8 transheterozygotes also show duplicated scutellar bristles, which are fully and partially suppressed in males and females, respectively, by ASPPUbi-p63E.GFP, and partially suppressed in both males and females by ASPPFA.Ubi-p63E.GFP.
