Detailed Description
Statement
Reference

Marked enok1 mutant female germline stem cells (GSCs) are present only 2 days after clone induction (ACI), but absent at 21 days ACI. Control clones are present at 21 days ACI. The mutant cells differentiate into marked mutant cysts. The cells in the mutant clones do not display signs of apoptosis.

Tracing of homozygous enok1 mutant cap cells in mosaic germaria for 21 days after eclosion reveals that the proportion of mutant clones drops dramatically over the time course, while the percentage the control ones remains steady.

Females heterozygous for enok1 have normal germarium cap cell numbers.

Homozygous somatic clones in the wing disc are not significantly different in size to wild type controls.

Homozygotes tend to enter the wandering third instar larval stage at about 7 days after larval hatching (ALH) at 25oC while their heterozygous counterparts take only 3.5 to 4.0 days. Approximately half of the animals die before pupariation formation. Those that pupate do so at around 10 days ALH. Homozygotes never eclose as adults. Homozygous mutant clones exhibit defects in the mushroom body. Mushroom bodies contain only what appears to be a γ lobe and have a reduced cell number. The clones stop adding neurons to the mushroom body by 2.5 days ALH. When mitotic recombination is induced at different times the normal progression through γ, α'/β', and finally α/β neurons is seen and that transitions between cell types occur at normal times. Branched α'/β', and α/β can be generated in late-induced enok1 clones. enok1 clones in the wing disc show no proliferation defects. Throughout the life of females generating germ-line clone homozygous enok1 eggs, a slow but steady decline in the number of eggs laid is seen when compared to wild-type.

Statement
Reference

The germarium cap cell loss caused by N264-39/+ is significantly enhanced by enok1/+.

Throughout the life of females generating germ-line clone homozygous enok1 eggs, a slow but steady decline in the number of eggs laid is seen when compared to wild-type.
