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

Third instar larval neuroblasts of tefu^unspecified mutants have an average of 3 fused chromosome ends per cell.

(Bi et al., 2005)

Anaphase bridges are sometimes seen in mutant imaginal discs.

(Oikemus et al., 2004)

Escaper adult homozygotes have eyes that are smaller than normal, have a rough phenotype and are missing some bristles. Mutant wing discs contain significantly more mitotic cells 25 minutes after irradiation compared to control wild-type discs. At later time points following irradiation, G2 arrest occurs normally in mutant wing discs.

Additional Comments

Genetic Interactions

Statement

Reference

The chromosome fusion phenotype seen in third instar larval neuroblasts of tefu^unspecified mutants is enhanced from an average of approximately 3 fusions per nucleus to an average of approximately 5 per nucleus by mei-41^D9. mei-41^29D and mei-41^RT1 are stronger enhancers of this phenotype (7 fusions per nucleus), with the latter also causing polyploidy in 19% of cases. In these polyploid nuclei, most chromosome ends are fused. This phenotype is also weakly enhanced by mus304^D3/mus304^D3 and more strongly enhanced by mus304^D1/mus304^D3 (5.35 fusions on average) and mus304^D1/mus304^D1 (7.12 fusions per nucleus and 20% of these nuclei are polyploid).

tefu^unspecified; mei-41^RT1 and tefu^unspecified; mei-41^29D double mutants develop more slowly than wild-type animals and arrest as third instar larvae for several days before death. There are fewer mitotic cells in the proliferating tissues of these double mutants.

(Bi et al., 2005)

mei-41^unspecified tefu^unspecified double mutant third instar larvae usually have melanotic tumours.
