The elimination of cells expressing Atg1[Scer\UAS.cSa] under the control of Scer\GAL4[Act5C.PP] from the wing disc is delayed by co-expression of Rheb[AV4].
The rough-eye phenotype observed in animals expressing Hsap\MAPT[V337M.Scer\UAS] under the control of Scer\GAL4[GMR.PF] is enhanced by co-expression of Rheb[AV4]. This enhancement is blocked in a Cdk4[3]/+ background, or by co-expressing dap[Scer\UAS.cdNa] and Rbf[Scer\UAS.cDa]. The rough-eye phenotype observed in animals expressing Hsap\MJD[tr.Q78.Scer\UAS.T:Ivir\HA1] in the eye under the control of Scer\GAL4[GMR.PF] is not modified by co-expression of Rheb[AV4].
Expression of RhebAV4, under the control of Scer\GAL4GMR.PF, produces a greatly enlarged eye.
Co-expression of RhebAV4 results in a strong enhancement of Scer\GAL4GMR.PF>foxoGS9928, leading to loss of virtually all ommatidia in females and pupal lethality in males with massive tissue degeneration in the head of late pupae. These phenotypes are partially suppressed by Akt1Scer\UAS.cSa overexpression.
Lethality acts in the second larval instar. Generation of clones of cells in the eye disc that overexpress DRheb results in enlarged eyes and head, while generation of loss-of-function clones in a sensitized (Minute) background results in a dramatic reduction of eye and head size.
Expression of RhebAV4 driven by Scer\GAL4byn-Gal4 causes lethality. This expression also causes a dramatically enlarged (both in width and length) hindgut in the first instar larva. Expression of RhebAV4 driven by Scer\GAL4GMR.PF results in marked overgrowth of the eye compared with wild type. Expression of RhebAV4 driven by Scer\GAL4Act5C.PI results in an enlarged eye, antenna and head. When compared to wild-type eyes, the ommatidia are much larger, are not organized into the normal hexagonal array and are frequently flanked by extra bristles. These bristles are thicker than in wild type. Embryos homozygous for RhebAV4 hatch into first instar larvae that grow very slowly, move lethargically, and die by 72 hours without molting into second instar larvae. Heads and eyes containing multiple RhebAV4 homozygous clones are dramatically reduced in size compared to those containing wild-type clones. Sections of eyes with RhebAV4 homozygous clones show disorganized, smaller ommatidia composed of smaller cells. Heterozygous RhebAV4 larvae usually emerge from the pupal case at the same time as in wild type. In the presence of rapamycin, however, RhebAV4 heterozygotes emerge two days later than their wild-type siblings.
