The Dwil\GK18382 genomic locus is cloned into a modified pBw plasmid (with the Scer\GAL4, terminator and promoter regions removed) and inserted at position 68A4 in Drosophila melanogaster flies using attP2.
The addition of two copies of Dwil\GK18382+ta to wild-type D. melanogaster flies results in a wider gap between the dorsal appendages. There is also a clear increase in the area posterior to the base of the dorsal appendages.
Dwil\GK18382+ta is a suppressor | partially of egg chorion phenotype of grk2B6/grk2E12
Dwil\GK18382+ta is a suppressor | partially of dorsal appendage phenotype of grk2B6/grk2E12
The presence of one or two copies of Dwil\GK18382+ta in grk2B6/grk2E12 mutant D. melanogaster flies results in four distinct eggshell phenotypes. Most eggshells, 69% and 78% from one and two copies of Dwil\GK18382+ta, respectively, are wild-type or wild-type with an enlarger area posterior to the base of the dorsal appendages, similar to wild-type flies expressing Dwil\GK18382+ta. A dorsal ridge-like morphology is found in 10% and 1% of the eggshells from one and two copies of Dwil\GK18382+ta, respectively.
In 13% and 18% of the eggshells from in grk2B6/grk2E12 mutant D. melanogaster with one and two copies of Dwil\GK18382+ta, respectively, there is a single or fused dorsal appendage.
In 8% and 3% of the eggshells from in grk2B6/grk2E12 mutant D. melanogaster with one and two copies of Dwil\GK18382+ta, respectively, the eggshells are collapsed and the eggs unmountable.
