Insertion within the wisp coding region, 36 residues downstream of the initiation codon.
Insertion in the coding region, 105bp downstream of the start codon.
Oogenesis appears normal in homozygous females, and they lay the normal number of eggs, but embryos derived from homozygous or wispKG05287/Df(1)RA47 females mated to wild-type males do not show any development.
Embryos derived from wispKG05287/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 wispKG05287/Df(1)RA47 stage 8 oocytes appears normal. 79% of stage 14 wispKG05287/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.
wispKG05287/wisp[+] is an enhancer of lethal | embryonic stage | maternal effect phenotype of orbmel
wispKG05287/wisp[+] is a non-enhancer of visible phenotype of Hsap\PABPN117ala.Act88F
wispKG05287/wisp[+] is a non-suppressor of visible phenotype of Hsap\PABPN117ala.Act88F
wispKG05287/wisp[+] is a non-enhancer of wing phenotype of Hsap\PABPN117ala.Act88F
wispKG05287/wisp[+] is a non-suppressor of wing phenotype of Hsap\PABPN117ala.Act88F
The percentage of maternal effect embryonic lethality seen in embryos derived from orbmel homozygous females is increased by heterozygosity for wispKG05287. The percentage of ventralised embryos is not increased by heterozygosity for one copy of wispKG05287.
wispKG05287 does not alter the wing posture defects seen upon expression of Hsap\PABPN117ala.Act88F.
