Flies expressing sei3'UTR.Scer\UAS under the control of Scer\GAL4elav-C155 are less sensitive than wild-type flies to acute heat stress, with the time to total paralysis being significantly longer in the mutant flies than in wild-type controls.
The decreased time to total paralysis in response to heat stress which is seen in seiHP21840 flies is fully rescued by expression of sei3'UTR.Scer\UAS under the control of Scer\GAL4elav-C155.
