Cytology

Description

The Df(3R)abd-A^iab4,5-DB break lies at the 3' end of the iab-4 transcription unit.

(Cumberledge et al., 1990)

DNA deletion from +83 to +113, extending into Abd-B sequences.

(Busturia et al., 1989)

Deletion removes region between coordinates +85 and +113, removing 28kb.

Phenotypic Data

Phenotypic Class

female sterile | recessive

(Karch et al., 1985)

male sterile | recessive

(Crosby et al., 1993, Karch et al., 1985)

visible | recessive

Phenotype Manifest In

gonad | precursor

(Boyle and DiNardo, 1995)

Detailed Description

Statement

Reference

Gonadal precursors do not coalsce into a gonad. Pole cells are released from the stalled gonadal precursors and are scattered throughout the embryo.

(Boyle and DiNardo, 1995)

Segments A6 and A7 show a more posterior identity when heterozygous with Abd-B^- than when hemizygous.

(Hendrickson and Sakonju, 1995)

In homozygous adult males the fifth abdominal segment appears to be partially transformed towards A4.

(Crosby et al., 1993)

Hemizygotes show A1 is slightly modified towards a more posterior segment, transformation is stronger in homozygotes. In males the A5 tergite is depigmented and resembles A4.

(Busturia et al., 1989)

Homozygous males show a transformation of the fourth and fifth abdominal segments into the third.

Notes on Origin

Discoverer

Induced with: abd-A^iab4,5-DB.

(Cumberledge et al., 1990, Karch et al., 1985)

Comments

Mutations in iab-4 have effects on the abd-A transcription unit, so such mutations are considered to be simultaneously mutant for iab-4 and abd-A.

Sterility is complemented by Abd-B^iab5-301, Abd-B^M1 and Abd-B^StP20.
