Description

Maps to intron preceding exon 3. The Doc insertion in ey2 and the flea insertion in eyR map within 75 bases of each other.

flea element insertion within intron 1.

flea insertion into an eye-specific enhancer element.

Insertion of a flea element near the 5' end of the ey gene into a regulatory element required for expression in the eye primordia.

Detailed Description
Statement
Reference

eyR heterozygotes do not exhibit any size alterations or roughness in eyes when compared to control adults.

eyR/eyD animals have small eyes.

Homozygotes show 30% lethality. Eyes are reduced in size in homozygotes; 5% have eyes that are 0-25% of wild-type size, 19% have eyes that are 25-50% of wild-type size, 49% have eyes that are 50-75% of wild-type size and 27% have eyes that are 75-100% of wild-type size. Homozygotes have no overt defects in the mushroom body or central complex. 97% of eyR/eyJD flies have eyes which are 75-100% of wild-type size and 3% have eyes that are 50-75% of wild-type size. The flies have no overt defects in the mushroom body or central complex. 89% of eyR/eyD1Da flies have eyes which are 75-100% of wild-type size, 9% have eyes that are 50-75% of wild-type size, 1% have eyes that are 25-50% of wild-type size and 1% have eyes that are 0-25% of wild-type size. The flies have no overt defects in the mushroom body or central complex.

The medial lobe of the mushroom body is malformed, fused, missing or reduced in diameter in 38% of second instar larvae. The number of Kenyon cells is reduced. The diameter of the MB peduncle is not reduced. Embryonic pattern of mushroom body neuroblasts is apparently normal.

Adult eyes vary in size from full to nothing, eye disc varies from rudimentary to full-sized.

Eye size relative to that of wild type: .25-.50

Sacharov, 13th Aug. 1923.

Separable from: toyroo.

Comments
Comments

Sequencing of the toy gene in eyR mutants revealed a polymorphic C to T substitution in intron 5 and an insertion of the 429bp LTR of roo in intron 1.

Loss of ey expression.
