Expression of a PCR fragment that includes the full length Gycα99B gene is driven by a heat shock promoter.
Gycα99Bhs.PG rescues Gycα99B1
Gycα99Bhs.PG partially rescues Gycα99B1
Rescue of phototaxis and ERG mutant phenotypes of Gycα99B1 by Gycα99Bhs.PG is dependent on expression during the first half of metamorphosis. Heat shock for 3 hrs during adult life has no rescuing effect.
Expression of Gycα99Bhs.PG using heat shock during the first 48 hours of metamorphosis partially rescues positive phototaxis in Gycα99B1 flies.
