bqSi294 [hsp16.41p::FRT::mCherry::his-58::FRT::GFP::his-58 + unc-119(+)] II; bqSi614 [dat-1p::FLP D5::SL2::mNG + unc-119(+)] IV. Heat shock produces green nuclei in dopaminergic neurons and red nuclei elsewhere. Constitutive expression of diffusible mNeonGreen in dopaminergic neurons can mask GFP::HIS-58 signal.
