ljIs131 [myo-3p::GCaMP3::UrSL2::tagRFP-T]. hpIs758 [rig-3p::LoxP::eBFP::LoxP::Chrimson::wCherry + twk-40(s)p::Cre + myo-2p::wCherry]. Pick animals with red fluorescence to maintain. Shrinker. RFP expression in AVA and a few other neurons. Reversal upon green light illumination with ATR. hpIs758 is a spontaneous insertion of hpEx4080. Reference: Lu Y, et al. 2022. Current Biology (In Press).

hpIs717 [acr-2(s)p::LoxP::eBFP::LoxP::Chrimson::wCherry + unc-17p::Cre + lin-15(+)]. ljIs131 [myo-3p::GCaMP3::UrSL2::tagRFP-T]. Red fluorescence in motor neurons. Reference: Lu Y, et al. 2022. Current Biology (In Press).

hpIs774 [twk-40p(short)::GCaMP6s::mNeptune]. hpEx4081 [rig-3p::LoxP::eBFP::Stop::LoxP::gtACR2::wCherry + twk-40p(short)::Cre + myo-2p::RFP]. Pick RFP+ (pharynx) to maintain. Transgenic animals are GFP and RFP positive in multiple neurons in the head, but strong RFP signals in AVA neurite. Superficially wild type. Activation of gtACR2 decreases AVA and AVB’s calcium signals. hpEx4081 can be maintained by picking animals with weak pharyngeal RFP signals (seems to be a common artifact of the Cre-LoxP system).

hpIs814 [flp-18p::LoxP::eBFP::Stop::LoxP::TeTx::wCherry + twk-40p(short)::Cre]. Red fluorescence in AVA. Slow forward and backward movement, with reduced reversals.

hpIs721 [rig-3p::FRT::Stop::FRT::snb-1::GFP + nmr-1p::FLP::FLP + myo-2p::RFP]. hpIs811 [flp-18p::LoxP::eBFP::Stop::LoxP::TeTx::Cherry + twk-40p(short)::Cre]. Transgenic animals have pharyngeal RFP signal; GFP puncta are visible in AVA soma but not along the VNC; RFP signals along AVA neurite.

hpIs824 [flp-18p::LoxP::eBFP::Stop::LoxP::gtACR2::wCherry + twk-40p(short)::Cre]. Red fluorescence in AVA soma and neurites of the VNC. Activation of gtACR2 inhibits both forward and backward movement.

hpIs774 [twk-40p(short)::GCaMP6s::mNeptune]. hpEx4292 [pdf-1p::LoxP::eBFP::LoxP::gtACR2::Cherry + twk-40p(short)::Cre + lin-15(+)]. Pick non-Muv to maintain. Red and green fluorescence in multiple head neurons. Activation of gtACR2 reduces AVB signals but does not generate specific changes in AVA.

hpIs819 [twk-40p(short)::GCaMP::T2A::NLS::mNeptune + lin-15(+)]. hpIs810 [flp-18p::LoxP::eBFP::Stop::LoxP::TeTx::wCherry + twk-40p(short)::Cre]. Transgenic animals exhibit strong RFP signals in AVA soma and neurites; cytoplasmic GFP and RFP in AVA, AVE, AVB and some neurons in RVG and tail (DVA).

hpIs814 [flp-18p::LoxP::eBFP::Stop::LoxP::TeTx::wCherry + twk-40p(short)::Cre]. Red fluorescence in AVA. twk-40(hp834) is a loss-of-function allele. twk-40(hp834) itself is highly loopy and a weak backward coiler. The presence of hpIs814 in the background reduces body bending and speed compared to twk-40(hp834) alone.

hpIs814 [flp-18p::LoxP::eBFP::Stop::LoxP::TeTx::wCherry + twk-40p(short)::Cre]. hpEx4363 [npr-4p::ins-22::pHluorin + myo-2p::wCherry]. Pick wCherry+ (pharynx) animals to maintain. Red fluorescence in AVA.

hpIs758 [rig-3p::LoxP::eBFP::LoxP::Chrimson::wCherry + twk-40p(short)::Cre + myo-2p::wCherry]. hpIs814 [flp-18p::LoxP::eBFP::Stop::LoxP::TeTx::wCherry + twk-40p(short)::Cre]. RFP positive in AVA soma and neurite along the VNC. Weak pharyngeal RFP. Flat and slow movement without ATR or LED stimulation. Chrimson activation induces loopy reversal but not loopy forward after 5min.
