The P1 isoform of ine is driven by a heat shock promoter.
wild-type
Suppression of the downturned wing phenotype of Sh14 ine1 occurs upon the induction of inehs.P1 by a single heat pulse immediately before eclosion. Induction of inehs.P1 after eclosion did not rescue the downturned wings phenotype.
inehs.P1 rescues ineunspecified
inehs.P1 rescues ine1
inehs.P1 completely rescues the increased sensitivity of ine mutant flies to food medium containing NaCl, even in the absence of heat shock.
