Detailed Description
Statement
Reference

tor13D mutant embryos display a highly penetrant pole-hole phenotype.

At 22oC, embryos derived from heterozygous females differentiate only rudimentary cuticle structures.

Visceral mesoderm of the trunk, which normally gives rise to the visceral muscles of the midgut is absent. The posterior portion of the mesoderm produces visceral muscle fibres which attach to the hindgut epithelium. A fraction of the endoderm cells, which contacts the visceral mesoderm underlying the hindgut, takes on epithelial characteristics.

Embryos lack anteriormost head structures.

The abdominal gt stripe extends all the way to the posterior pole, the anterior-most head patch of gt disappears and the remainder of the gt pattern is expanded and shifted.

Embryos derived from heterozygous females develop normally up to the blastoderm stage. At 18oC only the most posterior larval structures develop. At higher temperatures, posterior abdominal segments and anterior head segments may develop in a fraction of the embryos.

Statement
Reference

Heterozygous females carrying tor13D produce embryos that produce very little cuticle. This phenotype is weakly suppressed if the females are carrying one copy of Shc111-40 or ShcBG; the embryos develop more cuticle and show posterior structures such as Filzkorper and Tuft structures. The phenotype is completely suppressed if the tor13D/+ females also carry homozygous Shc111-40 or ShcBG germline clones; embryos look normal and can hatch. dosP115 partially suppresses the phenotype of embryos derived from tor13D/+ females.

The embryonic phenotype is suppressed by gtA8 : there is an increase in the proportion of embryos that form cuticle and a decrease in the proportion of embryos that form empty sacs.
