Excision of P{EPgy2}pds5EY06473 using Δ2-3 results in a deleted sequence 5' to the insertion site extending upstream of the pds5 transcription start site.
imaginal disc (with pds5e6)
Homozygous pds5e3 and heterozygous pds5e3/pds5e6 mutants are lethal in late third instar to early pupal stages of development. Late third instar larvae of both mutants display small or missing imaginal discs, and the larval brains are approximately half the volume of wild-type, consistent with a mitotic defect.
The vast majority of metaphases in pds5e3 are abnormal. Nearly all display aneuploidy (approximately 100%), and most display precocious sister chromatid separation (65%). By contrast approximately 15.4% of the pds5e3/+ heterozygote metaphases show aneuploidy and 12.8% exhibit sister chromatid separation, similar to the frequencies observed with wild-type neuroblasts.
The salivary glands of homozygous pds5e3 mutants are reduced. In size-matched third instars, the pds5e3 mutant chromosomes are thicker and less extended than in wild-type.
pds5[+]/pds5e3 is an enhancer of visible phenotype of Scer\GAL4da.G32, waplAG.UAS.Tag:HA
pds5[+]/pds5e3 is an enhancer of sex comb | ectopic phenotype of Scer\GAL4da.G32, waplAG.UAS.Tag:HA
pds5[+]/pds5e3 is an enhancer of wing margin phenotype of ctK
The addition of pds5e3/+ further darkens the eye colour of flies homozygous for P{wen.8}10C in a waplAG/+ w[-] background.
pds5e3/+ enhances the extra sex comb phenotype caused by expression of waplAG.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4da.G32.
pds5e6/pds5e3 is rescued by pds5Chi.EGFP
pds5Chi.T:Avic\GFP-EGFP rescues pds5e3/pds5e6 animals to adulthood.
