Detailed Description
Statement
Reference

Homozygous germ-line clones form completely dorsalised embryos.

dl15 mutant larvae dissected and exposed to air for 60 minutes show much reduced melanization, and melanin deposition on cuticles is substantially reduced compared to wild-type larvae under the same conditions.

Lowering the dose of dl maternally reduced the width of the embryonic mesoderm from 18 cells to 12-14 cells.

Embryos derived from homozygous females have a completely dorsalised cuticle. This phenotype is partially rescued if the females are also carrying dlαTub84B.PM; the resulting embryos have well defined dorsoventral polarity and have ventral denticle belts.

Statement
Reference

dl15 fails to suppress the melanotic mass phenotype seen in Atg61 mutant third instar larvae.

Homozygous dl15, eca1 germ-line clones produce embryos that form cuticles lateralised at the filzkorper level - a long dorsalised cuticle with a characteristic filzkorper ring. Homozygous dl15, bai1 germ-line clones produce embryos that form cuticles lateralised at the filzkorper level - a long dorsalised cuticle with a characteristic filzkorper ring.

The influence of sog mutants on the mesoderm of dl mutants is strictly maternal.
