Phenotypic Data

Phenotype Manifest In
Detailed Description
Statement
Reference

Approximately 80% of grk2E12/+ females lay eggs with fusion of dorsal appendages.

The posterior follicle cell phenotype of Merts1 is suppressed entirely by grk2E12.

The posterior MTOC fails to disassemble in mutant oocytes, resulting in a focus of microtubules at the posterior pole.

Embryos laid by homozygous grk2B6 mothers are strongly ventralised.

Eggs produced by homozygous females have a double micropyle.

grk2B6/grk2E12 egg chambers show a duplication of all three anterior follicle cell types at the posterior pole.

Additional Comments
Genetic Interactions
Statement
Reference

Heterozygosity for aretQB reduces the penetrance of dorsal appendage loss or fusion phenotypes in eggs laid by grk2E12/+ females, from 80% to 40%.

Xenogenetic Interactions
Statement
Reference

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.
