external sensory organ precursor cell IIIb & S phase
PNS glial cell & S phase
dap4 does not protect Df(1)su(s)R194/+ clones in the eye; Df(1)su(s)R194/+ ; dap4 clones are not recovered in the adult eye in animals with mosaic eyes containing two genotypes of cells with respect to RpL36; cells which are Df(1)su(s)R194/+ and cells in which the haplo-insufficiency of Df(1)su(s)R194/+ for RpL36 has been rescued by RpL36+t4 (in a wild-type background the Df(1)su(s)R194/+ clones are eliminated by cell competition and are not seen in the adult eye in these animals). Also, dap4 does not prevent apoptosis of Df(1)su(s)R194/+ cells in the wing.
The mitotic embryonic phenotype of CycAC8LR1 single mutants, in which mitosis 16 does not occur, is not suppressed in dap4; CycAC8LR1 double mutants. However, the double mutants do enter another S phase after the stage at which mitosis occurs in equivalent wild-type embryos.
Eye disc precluster cells mutant for both dap4 and Rbf14 continue to cycle instead of arresting. In addition, no G1 arrest occurs anterior to the morphogenetic furrow, all cells enter the second mitotic wave, and cells continue to cycle more posteriorly.
