Insertion of a P-element in 3' to 5' orientation after nucleotide 6510 in exon 10, introducing an in-frame stop codon that is predicted to produce a truncated protein lacking the conserved C-terminal domain.

Number of mitotic cells per midgut in cicfet-E11 heterozygote adults is not significantly changed compared to wild-type but it is significantly increased both in cicfet-U6/cicfet-E11 and cicfet-T6/cicfet-E11 transheterozygotes.
Approximately 12.9% of cicfet-E11/cicfet-U6 females exhibit a weak eggshell phenotype. The dorsal midline is expanded and the appendages are broader and positioned laterally with a trace of ventral collar material. The dorsalmost region remains free of appendage material.
Approximately 19.3% of cicfet-U6/cicfet-E11 females exhibit a moderate eggshell phenotype. The dorsal midline is expanded and the appendages are broader and positioned laterally and exhibit a ventral collar of ectopic appendage-like material. The dorsalmost region remains free of appendage material.
Approximately 30.0% of cicfet-U6/cicfet-E11 exhibit a moderate-severe eggshell phenotype. The dorsal midline is expanded and the appendages are broader and positioned laterally and exhibit a pronounced ventral collar of ectopic appendage-like material. The dorsalmost region remains free of appendage material.
Eggs derived from cicfet-U6/cicfet-E11 females are dorsalised. The eggs are shorter than normal and have broader dorsal appendages that are shifted laterally, with appendage base material encircling the entire anterior circumference of the egg. Embryos derived from cicfet-U6/cicfet-E11 females fail to hatch and are dorsalised (the secreted cuticle consists entirely of dorsal epidermis). cicfet-U6/cicfet-E11 adults have smaller wings than normal, with vein thickening and blistering. Eggs produced by females with homozygous germline clones are wild-type in appearance (not dorsalised), but 100% of the embryos derived from these eggs fail to hatch. The cuticle has normal dorso-ventral polarity, but shows expansion of the termini at the expense of segmentation (resembling a tor gain-of-function phenotype). Eggs derived from females carrying homozygous follicle cell clones are wild-type in appearance (not dorsalised). 13% of the embryos derived from these females fail to hatch (of these, 10% are locally dorsalised along the anterior-posterior axis and 1% are completely dorsalised), and 87% hatch. cicfet-T6/cicfet-E11 females lay eggs with a dorsalised eggshell and embryo.
cic[+]/cicfet-E11 is a suppressor | partially of lethal | dominant | maternal effect | embryonic stage phenotype of spzD1
cicfet-U6/cicfet-E11 has dorsal appendage phenotype, suppressible by mirr6D1
cicfet-U6/cicfet-E11 has egg phenotype, suppressible by mirr6D1
Egfrt1, cicfet-T6/cicfet-E11 has embryonic/first instar larval cuticle phenotype
Egfrt1, cicfet-T6/cicfet-E11 has egg chorion phenotype
Approximately 34.4% of cicfet-E11/mirr6D1 cicfet-U6 females exhibit a weak eggshell phenotype. Approximately 37.4% of cicfet-U6/mirr6D1 cicfet-E11 females exhibit a weak-moderate eggshell phenotype. Approximately 24.5% of cicfet-U6/mirr6D1 cicfet-E11 females exhibit a moderate eggshell phenotype. Approximately 37.9% of cicfet-U6/mirr6D1 cicfet-E11 females exhibit a moderate-severe eggshell phenotype. The dorsal midline is expanded and the appendages are broader and positioned laterally and exhibit a thick ventral collar of ectopic appendage-like material. The dorsalmost region remains free of appendage material. There is an increase in the weak phenotype, and a decrease in the severe phenotype compared to the cicfet-E11/cicfet-U6 mutant, indicating that mirr6D1 suppresses the cicfet-E11/cicfet-U6 phenotype.
Egfrt1/Egfrt1 ; cicfet-T6/cicfet-E11 females lay eggs with a dorsalised embryo (like cicfet-T6/cicfet-E11 single mutant females) and an eggshell that shows a combination of cic and Egfr mutant phenotypes; the dorsal appendages are broadened (as in cic mutants) but are positioned closer to the dorsal midline (as in Egfr mutants).
Selected as: a dominant suppressor of the sterility of spzD1/+ females.
