Strain Genotype Description
ZM5488 hpIs202. hpIs202 [ceh-10p::GFP + lin-15(+)]. GFP is expressed by four neurons RID, AIY, CAN, ALA, and one sheath cell. References: Wang et al., 2015. Development 142(8):1447-57. doi: 10.1242/dev.119479. Lim et al., 2016. Elife 5. pii: e19887. doi: 10.7554/eLife.19887.
ZM9078 hpIs587. hpIs587 [flp-14p::GCaMP6::wCherry + lin-15(+)]. CGaMP6 and wCherry expressed in RID, ALA, some head neurons, a mid-body neuron and a tail neuron. Reference: Lim et al., 2016. Elife 5. pii: e19887. doi: 10.7554/eLife.19887.
CGC52 dpy-5(e61)/hT2 I; unc-36(e251)/hT2 [bli-4(e937) let-?(h661) umnIs42] III. umnIs42 [myo-2p::mKate2 + NeoR, I: 6284001 (intergenic)] III. 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. (Mark Edgley)]
RM2576 cho-1(tm373) IV. Canonical allele. Superficially wild-type. Frequency of spontaneous reversals approximately twice that of wild type.
