Detailed Description
Statement
Reference

Homozygous embryos have a "faint little ball" phenotype; they lack denticle setae and anterior, posterior and ventral cuticular structures.

Egfrf3/Df(2R)Egfr3 embryos exhibit no ventral cuticle and the anterior has a large hole. No Egfrf3/Df(2R)Egfr3 mutant discs could be in vivo cultured.

Egfrf3/Egfrt2 wings have a gap in L4 wing vein.

Transheterozygous females with Egfrt1 display egg chambers with gaps in the follicular epithelium that uncover the nurse cells. Eggs derived from these females display weak or intermediate ventralised phenotypes.

Enhances the female sterility and adult morphological defects of Egfrt1. Rarely survives as transheterozygote with the semi-viable Egfrtop-CA allele.

Homozygotes and hemizygotes display a severe 'flb' phenotype. Embryos produced from heteroallelic combination with Egfrt1 have a severe ventralised phenotype, reduction in size of their dorsal appendage.

Genetic Interactions
Statement
Reference

Suppresses the recruitment defects in the eye caused by expression of atoScer\UAS.cJa under the control of Scer\GAL4sca-109-68, although abnormal pattern formation still occurs. Many R7 cells differentiate in sev14 flies expressing atoScer\UAS.cJa under the control of Scer\GAL4sca-109-68 (in contrast to sev14 flies which lack R7 photoreceptors). This rescue of R7 formation by atoScer\UAS.cJa expressed under the control of Scer\GAL4sca-109-68 is strongly suppressed if the flies are also carrying Egfrf3.

Has no effect on the eye phenotype of Nspl-1.

Eye supernumerary R7 cell phenotype of sl1 and sl2 is almost completely suppressed by reducing the dosage of Egfr.

Egfrf3/Egfrt2 vein gap can be rescued by one copy of sev::tor13D.hs.sev. Ectopic expression also causes extra vein phenotype, notably around the distal end of L2 and broadening or deltas at the distal tips of most of the veins.

No effect on the faf eye phenotype.

Suppression of the rough eye phenotype (formation of extra R7 cells) caused by P{sev-svp2} and enhancement of the P{ro-svp1} rough eye phenotype (loss of one or more outer photoreceptors from many of the ommatidia).
