    Detailed Description
    Statement
    Reference

    When mutant somatic clones are made in the border cells no effect is seen.

    Homozygous embryos show loss of VA2 muscle precursor cells (25% of hemisegments contain VA2 precursor cells).

    Induction of somatic clones in the developing eye results in the frequent absence of photoreceptor cells of different identities.

    Able to induce R7 cell development at a reduced frequency. dosR31/dosP115 transheterozygotes are lethal. Repeated heat shock induction of P{sE-dos} during development is sufficient to rescue the lethality of dosR31 and dosP115 homozygotes and dosR31/dosP115 transheterozygotes. Mitotic clones in the eye rarely differentiate photoreceptor cells. In the wing clonal cells are unable to differentiate vein structures. Embryos derived from germline clones exhibit very distinct defects in the terminal structures, they rarely differentiate filzkorper and the abdominal segment A8 is frequently affected and the head skeleton is reduced in size.

    Additional Comments
    Genetic Interactions
    Statement
    Reference

    One copy of dosR31 enhances the reduction in wing blade area seen in homozygous sl2 males.

    One copy of dosR31 partially suppresses the ectopic wing vein phenotype seen in sl2 homozygotes.

    One copy of dosR31 partially suppresses the percentage of sl2 mutant ommatidia that contain extra R7 photoreceptors.

    The addition of dosR31 almost completely suppresses the rough eye phenotype seen in sevS11.T:Hsap\MYC animals. The addition of both dosR31 and doshs.2sev does not suppress the phenotype. The addition of both dosR31 and dosR644K.R696K.hs.2sev or dosR696K.hs.2sev continues to suppress the rough eye phenotype. The addition of both dosR31 and dosR644K.hs.2sev partially the rough eye phenotype.

    Expression of csw::Src64Bsrc90.Scer\UAS under the control of Scer\GAL4twi.PG significantly suppresses the loss of VA2 muscle precursor cells seen in dosR31 embryos (41% of hemisegments have VA2 cells).

    The addition of heterozygous dosR31 suppresses the rough eye phenotype seen in sevS11.T:Hsap\MYC flies.

    Fails to suppress the mutant eye phenotype of Ras85DV12. Removal of one copy of dos from sev::tor13D:Y2546F.hs.sev individuals causes a significant reduction in ommatidia with multiple R7 cells.

    The addition of dos::Hsap\GAB1hs.T:Avic\GFP to dosR31 homozygotes or dosP115/dosR31 flies leads to the recovery of fully viable flies.

    Complementation and Rescue Data
    Partially rescued by
    Comments

    The addition of doshs.T:Avic\GFP to dosR31 homozygotes or dosP115/dosR31 flies leads to the recovery of fully viable flies. The addition of dosW104A.hs.T:Avic\GFP or dosΔPH.hs.T:Avic\GFP to dosR31 homozygotes or dosP115/dosR31 flies fails to produce viable flies. A single copy of dosY316F.hs rescues the eye phenotype seen in the eye when dosR31 somatic clones are induced. The addition of dosW104A.mBa fails to rescue this phenotype. The addition of doshs.T:Avic\GFP (but not dosΔPH.hs.T:Avic\GFP) to dosR31/sevS11.T:Hsap\MYC flies restores the multiple R7 phenotype seen in dosΔPH.hs.T:Avic\GFP/sevS11.T:Hsap\MYC flies.
