Detailed Description
Statement
Reference

sktl2.3/sktlΔ15 females show defects in the localisation of the oocyte nucleus (31% of stage 9-10 oocytes show this phenotype) and they lay eggs that are ventralised.

Lethality acts in the late first larval instar. Mutants show no morphological abnormalities. When the sktlΔ15 chromosome is heterozygous with the sktlk07505, insck07505 chromosome, late second instar lethality results. No abnormalities were detectable in the larval neuromuscular junction electrophysiological preparation indicating no defect in vesicular trafficking nor dense core vesicle secretion. Germ line clone analysis revealed arrest at stage 10 of oogenesis. Arrested egg chambers show defects in nurse cell nuclei. The few eggs that develop are small and show defects in the dorsal appendages. Clonal analysis in the wing revealed a requirement for sktl for cell viability and/or growth. The few bristles that are recovered in clones are wavy or bent, indicating cytoskeletal defects. Clonal analysis in the eye produced no mutant clones, suggesting a requirement for sktl for cell viability or cell division in imaginal discs.

baz4/+ enhances the nucleus mislocalisation defect seen in stage 9-10 sktl2.3/sktlΔ15 oocytes, such that 63% have a mislocalised nucleus.

ash122 sktlΔ15 double heterozygotes show a homeotic transformation of third leg to second leg (3.7% penetrance). ash22 sktlΔ15 double heterozygotes show a homeotic transformation of third leg to second leg (28.6% penetrance). ash218 sktlΔ15 double heterozygotes show a homeotic transformation of third leg to second leg (9.4% penetrance). sktlΔ15/+ ; ash21/ash218 larvae have delayed development and die at an earlier stage than ash21/ash218 larvae.
