Detailed Description

Statement

Reference

Scer\GAL4^Act.PU-mediated expression of gwl^{NLSmut.Scer\UAS.P\T.T:Hsap\MYC} in a gwl^Sr3/gwl^Sr6 mutants background results in viable but female sterile flies. Ovaries are completely lacking.

(Wang et al., 2013)

gwl^Sr3 mutants are homozygous viable and exhibit an eclosion delay. gwl^Sr3 adults display variably rough eyes, eroded wing margins, and missing bristles. Both sexes are sterile with strongly reduced gonads. There are few germ cells, even in newly eclosed adults; none remain a few days later.

gwl^Sr3/gwl^6a mutants exhibit mitotic defects, leading to an increase in the mitotic index with more cells in anaphase. Mutant neuroblasts show a high frequency of defective chromatin condensation. Some regions of chromatin appear undercondensed and other regions are overcondensed. In some cells the chromosomes are uniformly overcondensed, suggesting a lengthy pre-anaphase delay.

gwl^Sr3/gwl^Sr6 adults eclose (after a delay), with variably rough eyes, eroded wing margins, missing bristles and strongly reduced gonads, though viability is reduced.
