vpIs1 [elt-3::GFP + lin-15(+)] X. Heterozygotes are WT with pharyngeal GFP signal, and segregate WT GFP, arrested nT1[qIs51] aneuploids, and non-GFP ok546 homozygotes (Unc Egl). Homozygous nT1[qIs51] inviable. Pick WT GFP and check for correct segregation of progeny to maintain. Reference: Yamamoto Y, et al. PLoS Genet. 2011 Oct;7(10):e1002308.

Heterozygotes are WT and GFP+. Segregate more WT and GFP+, Dpys, and dead eggs. Dpys give only embryonic lethals.

zdIs5 [mec-4p::GFP + lin-15(+)] I. Homozygous nT1[qIs51] are inviable. mec-4::GFP is expressed in touch neurons. Heterozygotes are strong Egl Psa GFP+ and segregate dead eggs and non-GFP Unc Egl Psa that give only dead eggs at 25C.

ljfSi32 [egl-20 enhancer(-1261 – 610)::pes-10p::egl-17::mNG::SL2::2x mKate2::PH::3xHA::tbb-2 3'UTR loxN]) I. ljfSi10 [hlh-8p::2x mTurquoise2::PH::tbb-2 3'UTR loxN] II. Sex myoblast migration defects, Egl. EGL-17::mNG expression in a small number of posterior cells leads to posterior sex myoblast migration in hermaphrodites. egl-17(ljf14) was generated by replacing the endogenous egl-17 coding sequence with mNG::3xFlag. ljfSi32 is a single copy transgene inserted at Chr I:2851088, near ttTi4348.

cpIs89 [wrt-2p::2x mTurquoise2::PH::tbb-2 3'UTR loxN] I. cpIs85 [egl-20p::2x mKate2::PH::3xHA::tbb-2 3'UTR loxN] II. mNeonGreen::3xFlag tag inserted at the C-terminus of the endogenous egl-20 locus. 2x mTurquoise2::PH membrane marker expressed in seam cells, Q neuroblasts, and many hypodermal cells. Expression of 2x mKate2::PH membrane marker driven by egl-20 upstream intergenic sequence. cpIs89 is a single copy transgene inserted at Chr I:2851088 near ttTi4348 using Cas9-triggered homologous recombination. cpIs85 is a single copy transgene inserted at Chr II:8420157-8420243 near ttTi5605 using Cas9-triggered homologous recombination.

cpIs158 [myo-3p::pat-3sp::2x vhhGFP4::CD8 tm::2x mTurquoise2::PH::tbb-2 3'UTR loxN] I. cpIs130 [wrt-2p::2x mKate2::PH::3xHA::let-858 3'UTR::tag-168p::HisCl1::tbb-2 3'UTR loxN] II. YPET::3xFlag tag inserted at the C-terminus of the endogenous egl-20 locus. cpIs158 expresses a membrane-anchored anti-GFP nanobody (Morphotrap) in body wall muscles. This version of Morphotrap consists of extracellular 2x vhhGFP4 fused to a human CD8 transmembrane domain and intracellular 2x mTurquoise2. Endogenously tagged EGL-20::YPET::3xFlag is efficiently sequestered by the Morphotrap transgene (the transgene functions as expected for Wnt), leading to Q neuroblast migration defects. NOTE: cpIs158/Morphotrap does not capture all YPET-tagged extracellular proteins, so sequestration should be determined empirically. cpIs130 is a single copy transgene expressing a 2x mKate2::PH membrane marker in seam cells, Q neuroblasts, and many hypodermal cells, and HisCl1 expression from the tag-168 upstream intergenic sequence. Expression of HisCl1 from the single copy insertion does not appear to be sufficient for immobilizing animals. cpIs158 was inserted at Chr I:2851088 near ttTi4348 using Cas9-triggered homologous recombination. cpIs130 was inserted at Chr II:8420157-8420243 near ttTi5605.
