The heat shock promoter is not suppressed in hcrtr or dbh mutants.
Representative images of brains from larvae that do not (A) or do (B) contain the hsp:Hcrt transgene, fixed 30 min after HS, and processed for ISH using a hcrt-specific probe. hcrt overexpression levels are similar for hcrtr+/- (B), hcrtr-/- (B′), dbh+/- (B′′) and dbh-/- (B′′′) animals. Larvae were generated by crossing homozygous to heterozygous mutant animals, and brains were genotyped after imaging. Dark spots in (A-A′′′) are pigment cells. Endogenous hcrt expression is not observed in (A–A′′′) because ISH development was stopped before endogenous hcrt is detectable.
