Description

FlyBase curator comment: this entry is used to capture phenotypic information when the particular allele (or allele combination) used by the author could not be determined but the context of the experiment suggests that the phenotype being described is some kind of loss of function.

Detailed Description

Statement

Reference

Eggs derived from homozygous females show a "grandchildless knirps-like" phenotype; they lack polar granules and pole cells and show deletions of abdominal segments similar to that seen in kni mutant embryos. In addition, the cephalic furrow is shifted anteriorly at gastrulation, and deletions of anterior head structures are seen in the cuticle.

(Schupbach and Wieschaus, 1989)

Embryos derived from stau^unspecified mutant females lack pole cells, pole plasm and abdominal segments. The anterior part of the head is defective.

Additional Comments

Genetic Interactions

Statement

Reference

BicD^D stau^unspecified / egl^3e triple mutants exhibit a 46% hatch-rate, compared to BicD^D stau^unspecified double mutants, which exhibit a hatch-rate of 19%. This indicates suppression of the BicD^D stau^unspecified phenotype by egl^3e.

BicD^D stau^unspecified/Dhc64C^4-19 triple mutants exhibit a 39% hatch-rate, compared to BicD^D stau^unspecified double mutants, which exhibit a hatch-rate of 8%. This indicates suppression of the BicD^D stau^unspecified phenotype by Dhc64C^4-19.

BicD^D stau^unspecified / ctp^exc3 triple mutants exhibit a 0.7% hatch-rate, compared to 0.25% in BicD^D stau^unspecified mutants. This indicates a mild suppression of the BicD^D stau^unspecified by ctp^exc3. Removing one copy of ctp^exc3 suppresses the 'double abdomen' phenotype of BicD^D stau^unspecified and allows more wild-type cuticle to form. The percentage of bicaudal decreases from 97% (BicD^D stau^unspecified) to 57% (BicD^D stau^unspecified/ctp^exc3). This coincides with an increase in the number of asymmetric, headless and normal embryos.

BicD^D stau^unspecified/Lis-1^G10.14 triple mutants exhibit a 85% hatch-rate, compared to an 8% hatch-rate in BicD^D stau^unspecified control strains. This indicates suppression of the BicD^D stau^unspecified phenotype by Lis-1^G10.14.
