Detailed Description
Statement
Reference

Homozygous and dxENU/dx152 flies show wing vein thickening, with the severity of the phenotype being stronger in the dxENU/dx152 flies (homozygotes showing only a weak wing vein phenotype).

Homozygous females have an excess of microchaetae, having 133.13 +/- 1.88 thoracic microchaetae per heminotum (compared to the wild-type number of 130.35 +/- 1.54).

Thickened wing veins and wing margin loss.

Viable. Extra wing vein material at distal ends, nicked margins an tips. Ocelli are fused or closed, hairs and bristles are abnoral or missing. Weak rough eye phenotype: irregular ommatidia, bristles are duplicated or missing. No visual abnormality. Homozygotes rescue the mutant phenotype of NAx-E2, NAx-9 and NAx-75c transheterozygotes. 40% eggs from homozygous females fail to hatch: defective dorsal appendages and no cuticular structures. Hemizygote males with NAx-E2 have a low fertility. Nnd-1/dxENU and Nnd-2/dxENU transheterozygous flies never reach adulthood (stage of lethality not determined). An extra wild type copy of N suppresses the wing nicks and thickened veins, and partially suppresses the ocellar phenotype. An extra wild type copy of Dl or mam causes some pupal lethality, escapers have small eyes. Flies heterozygous for H and homozygous for dxENU have eyes smaller than wild type, infrequent missing or duplicated bristle phenotype and ommatidia are square wih a bristle at each corner.

Genetic Interactions
Statement
Reference

The percentage of NAx-9/NAx-E2 flies surviving to adulthood is dramatically increased by dxENU/+. Survival of NAx-9/NAx-E2 dxENU/+ flies to adulthood is significantly decreased by krzS047819/+ or krzS095214/+.

dxENU dominantly suppresses the loss of microchaetae seen in NMcd1, NMcd5 or NMcd8 heterozygotes, increasing the number of microchaetae per heminotum to 78.33 +/- 1.09, 94.25 +/- 1.15 or 90.30 +/- 1.61 respectively. dxENU dominantly enhances the increase in microchaetae seen when dshhs.PA is expressed using heat shock, increasing the number to 142.12 +/- 2.53 thoracic microchaetae per heminotum.

Triple homozygotes of Su(dx)sp with NAx-E2, dxENU are inviable. NAx-E2, dxENU/NAx-9+;Su(dx)1/+ are inviable, whereas Nnd-1, dxENU; Su(dx)1 are viable though the wing blade is reduced. The mutant wing, eye and ocelli phenotypes are dominantly suppressed by Su(dx)1, Su(dx)2 and Su(dx)sp. Flies that are dxENU/Y; Su(dx)1/+; mam10/+ are viable but display clear dx phenotypes in the ocelli and wings. Flies that are dxENU/Y; Su(dx)1/+; Dl9P/+ are viable but display clear dx phenotypes in the ocelli and wings.
