Detailed Description

Reference

In contrast to control flies, ine3 mutant flies die within 10 days on hypertonic media. As in wild type, no tissue damage is observed in the anterior hindgut.

When maintained on hypertonic media, the hemolymph volume and total body water content of ine3 mutant flies declines dramatically compared to controls. Hemolymph volume and total body water content of ine3 mutant flies are unaffected on normal medium.

The median survival rate of ine3 mutant flies in response to lack of water is reduced compared to wild type controls. Survival rate following starvation (in the presence of sufficient water) is unchanged compared to controls.

ine3 flies show significantly greater lethality than wild-type flies when maintained for 4 days on food medium containing 0.2M NaCl. The flies show essentially complete inviability after 4 days on food medium containing 0.4M NaCl (in contrast to wild type flies, where 90% survive). Viability after 4 days on food medium containing 0M or 0.1M NaCl is similar to wild type. The flies also show increased sensitivity to KCl and sorbitol compared to wild-type flies. Mutant flies show normal sensitivity to heat shock stresses.

Expression of ineRA.Scer\UAS in the hindgut under the control of Scer\GAL4Irk2.PL rescues the lethality seen when ine3 mutant flies are raised on hypertonic medium. Expressing ineRA.Scer\UAS in neurons (Scer\GAL4elav.PU) or glia (Scer\GAL4repo.PU) does not rescue the lethality.

Expression of ineRB.Scer\UAS in the hindgut under the control of Scer\GAL4Irk2.PL rescues the lethality seen when ine3 mutant flies are raised on hypertonic medium. Expressing ineRB.Scer\UAS in neurons (Scer\GAL4elav.PU) or glia (Scer\GAL4repo.PU) does not rescue the lethality.

Expression of ineRA.Scer\UAS in the hindgut under the control of Scer\GAL4Irk2.PL completely rescues the reduction in hemolymph volume and total body water content seen when ine3 mutant flies are kept on a hypertonic medium.
