Expression of PIP4KScer\UAS.T:Avic\GFP-EGFP under the control of Scer\GAL4da.G32 results in an increase in larval body weight compared to controls. The mutant larvae show an acceleration in pupariation compared to wild type. Salivary gland cells are increased in size in the mutant larvae compared to wild type.
The expression of PIP4KScer\UAS.T:Avic\GFP-EGFP under the control of Scer\GAL4ninaE.PU rescues the increases in endosome-like vesicles and in multi-vesicular bodies observed in photoreceptors of PIP4K29 homozygous late pupae under light conditions.
The reduced body weight and reduced salivary gland cell size of PIP4K29 larvae relative to wild type is rescued by expression of PIP4KScer\UAS.T:Avic\GFP-EGFP under the control of Scer\GAL4da.G32.
