Detailed Description
Statement
Reference

Indirect flight muscles from Laspy41 and Lasp1/Laspy41 mutants show no gross defects, but sarcomeres as well as thin filaments are 12% shorter than wild type.

40-50% of Laspy41 mutant eggs fail to develop due to lack of fertilisation. The remaining embryos hatch and develop normally. Homozygous mutant Laspy41 females all contain normally developed ovaries.

20% of embryos of Laspy41/+ females develop pole cells at the anterior end of the embryo.

Laspy45, osk1/Laspy41 females have a grandchildless phenotype, which is rescued by expression of LaspL.Scer\UAS.P\T under the control of Scer\GAL4otd. The number of pole cells is partially rescued, increasing to 25 pole cells in stage 11 embryos.

The grandchildless phenotype of Laspy45, osk1/Laspy41 females is not rescued by expression of LaspWA.Scer\UAS.P\T or LaspS.Scer\UAS.P\T under the control of Scer\GAL4otd. There is no increase in the number of pole cells observed in these embryos.

The anterior patterning defects observed in embryos expressing oskM1R.fs(1)K10.3'UTR.Scer\UAS under the control of Scer\GAL4mat.αTub67C.T:Hsim\VP16 are significantly reduced in penetrance and severity in a Laspy41 background.

Expression of LaspL.Scer\UAS.P\T restores the hatching defect in Laspy41 mutants.
