When fed all-trans retinal, blue light stimulation (473 nm at 2 mW * mm^-2) of head induces reversals. GCaMP3 and and mCherry expression in command interneurons AVA, and nearby pharyngeal neurons I1, I4, M4, NSM. Worms were made by crossing the integrated strains QW309 and QW625.

Heterozygotes are WT mKate2+ and segregate WT mKate2+, DpyUnc, lethal mKate2+ hT2 homozygotes (arrest stage unknown) and dead eggs (aneuploids). Will throw an occasional mKate2+ Dpy non-Unc (similar events were observed in the parental hT2 strain). Pick WT mKate2+ and check for correct segregation of progeny to maintain. Derived by insertion of myo-2p::mKate2 transgene into hT2 balancer in parental strain KR2467 using CRISPR/Cas9. [NOTE: 3/1995: Apparently the lethal mutation is closely linked but not within the balanced region of hT2. It can occasionally recombine away so that the strain will segregate Bli-4 hT2 homozygotes.
