Internal deletion of P{lacW} of P{lacW}domk08108 progenitor, inactivating the w+mC allele.
lethal (with Df(2R)AA21)
visible (with domRNAi.Sym.UAS), with Scer\GAL4bbg-C96
98% of flies expressing domdsRNA.Sym.Scer\UAS under the control of Scer\GAL4bbg-C96 in a dom3/+ background show wing nicking.
dom3 homozygous female germ-line stem cells are lost from their stem cell niche at the same rate as wild-type female germ-line stem cells. However, 94% of dom3 homozygous clone follicle stem cells are lost from their niche within 17 days, compared to only 37.5% of cells in wild-type control clones. This is not accompanied by any increase in in apoptosis of these cells.
Lethality acts in the early pupal stages. Lymph glands are overgrown, more or less blackened, imaginal discs are reduced or normal, brain apparently normal. Females with germline clones do not lay eggs.
