Dataset

A set of transgenic insertion stocks derived by TE mobilization using the P-element construct P{SUPor-P}; created and vetted by the Gene Disruption Project (GDP). The P{SUPor-P} construct carries two visible markers: a w[+mC] mini-white marker flanked by su(Hw)-binding sites, designed to reduce the variablity of the phenotype of the white gene marker due position effects, in addition to the mini-yellow marker y[+mDint2].

hide Detailed Description
Statement
Reference
Oogenesis appears normal in homozygous females, and they lay the normal number of eggs, but embryos derived from homozygous or wisp[KG05287]/Df(1)RA47 females mated to wild-type males do not show any development. Embryos derived from wisp[KG05287]/Df(1)RA47 females do not complete meiosis. In 74% of embryos, a single meiotic spindle is visible which is thin or distorted and on which the chromosomes are scattered or separated in asymmetric pools. A second small spindle is sometimes present, which is nucleated by one or several lost chromosomes (8% of embryos). Among the remaining embryos, 15% are blocked in meiosis II; two meiotic spindles (which in most cases are abnormally arranged), can be seen. Meiotic figures in the mutant embryos correspond to either abnormal metaphase I or anaphase I. The karyosome in wisp[KG05287]/Df(1)RA47 stage 8 oocytes appears normal. 79% of stage 14 wisp[KG05287]/Df(1)RA47 oocytes do not maintain metaphase I arrest properly. The chromosomes separate along the spindle and do so asymmetrically, the fourth chromosome often migrating out of the spindle. The spindle is thin or irregular.
The percentage of maternal effect embryonic lethality seen in embryos derived from orb[mel] homozygous females is increased by heterozygosity for wisp[KG05287]. The percentage of ventralised embryos is not increased by heterozygosity for one copy of wisp[KG05287].
