Detailed Description
Statement
Reference

99% of lack15C homozygous progeny of lack15C homozygous mothers die as embryos. Most cuticles from these dead embryos have a hole in the dorsal posterior region extending from the spiracles to the posterior pole, or a more extensive dorsal hole (approximately 50%). These embryos also have variable head defects, and an excess of amnioserosa cells at stage 12 (336+/-47 (n=5) compared to 176+/-54 (n=3) for wild-type). From stage 14 onwards lack15C homozygous progeny of lack15C homozygous mothers display hindgut abnormalities: The hindgut is shorter and wider than in wild-type; bulges out of the dorsal surface of the embryo; and is splayed open, exposing the lumen. These embryos also display an abnormal variability in the number and shape of epithelial invaginations in the dorsal stomodeum.

Additional Comments

Statement
Reference

Smurf15C dominantly enhances the small and rough eye phenotype resulting from the expression of Scer\GAL4tub.PU>wtsScer\UAS.cYa.

Smurf15C dominantly enhances the enlarged eyes caused by overexpressing Scer\GAL4tub.PU>ykiScer\UAS.cHa.

Homozygous lack15C has no effect on the increased number of spectrosome-containing GSC-like cells seen in fu41 mutant germaria.

Expression of tkvca.bam.T:Avic\GFP enhances the delay in cystoblast differentiation seen in lack15C mutant germaria. Nealy 38% of ovarioles are composed of a tumorous germarium, and 62% of the ovarioles contains tumorous germaria that are attached to one or several egg chambers.

In piwiunspecified lack15C double mutant ovaries, most germaria contain supernumerary germline stem cells (GSCs) and a continuous supply of egg chambers, resembling the lack15C single mutant phenotype.

Embryonic lethality due to maternal and zygotic homozygosity for lack15C is partially suppressed (83% survival to adulthood) by heterozygosity for dppH46. The embryonic midgut phenotype of maternal and zygotic lack15C/lack15C embryos is fully suppressed by dppH46/+ and sogY506/sogY506 and partially suppressed by zen7/zen7 (in the latter embryos, the hindgut frequently fails to form its normal hook-like morphology). Maternal and zygotic homozygosity for lack15C partially suppresses the dominant lethality of dppH46 (83% survival to adulthood), but has no effect on the lethality or cuticle phenotypes due to homozygosity for dppH46. The weak dorsalisation phenotype exhibited by cuticles from sogY506 hemizygous embryos is enhanced to full dorsalisation (transformation of all ventral denticle belts into dorsal hairs) by maternal and zygotic homozygosity for lack15C.
