-mediated expression increases the fraction of wing disc cells in G1 phase and concomitantly decreases the fraction in G2.
Very few ovarioles accumulate more than one follicle stem cell (FSC) expressing Scer\GAL4tub
, indicating a modest FSC defect.
Expression of dapScer\UAS.cdNa
under the control of Scer\GAL4en-e16E
in the posterior compartment cells of embryos causes these cells to arrest in G1 and prevents their death through apoptosis.
Cells expressing dapScer\UAS.cdNa
have longer G1 phases than wild-type, though cell doubling times are not significantly different from wild-type, suggesting their G2 and S phases are shorter.
Ovarian follicle cells in somatic clones of dapScer\UAS.cdNa
after stage 6 of oogenesis have small nuclei and do not incorporate BrdU indicating a lack of S phases.
