Detailed Description

Statement

Reference

ImpL2^Def42 pupae exhibit increased body size in hypoxia (10% O[[2]]), but no body size changes in normoxia,(21% O[[2]]), compared to controls.

(Kapali et al., 2022)

The body size of ImpL2^Def20/ImpL2^Def42 mutants is increased relative to wild-type flies. The size increase is attributable primarily to an increase in the number of cells, because cell size is only slightly affected. Apart from the size and weight increase, ImpL2^Def20/ImpL2^Def42 flies appear completely normal and eclose at the expected frequency and are not delayed in development. The weight increase is more pronounced in ImpL2^Def20/ImpL2^Def42 females than in males, although the increases in wing area and cell number are similar. This differential effect is caused by enlarged ovaries.

Survival of ImpL2^Def20/ImpL2^Def42 early third instar larvae is severely compromised under starvation conditions.

Phenotype Manifest In

Additional Comments

Genetic Interactions

Statement

Reference

The increased body weight phenotype resulting from the overexpression of Ilp2^Scer\UAS.cBa via Scer\GAL4^arm.PS is dominantly enhanced by ImpL2^Def42.

Overexpression of Ilp2^Scer\UAS.cBa under the control of Scer\GAL4^arm.PS causes lethality in ImpL2^Def42/ImpL2^Def20 mutants.
