Bacteria. Contains eat-5 rescuing plasmid pRE5-7. Amp-R. Do not distribute this strain; other labs should request it from the CGC. This strain cannot be distributed to commercial organizations. Biosafety Level: BSL-1.

Bacteria. E. coli strain carrying an avr-15::GFP fusion plasmid. Amp-R. Sac I Pst I fragment from K10B8 fused to transmembrane GFP from TM-1. Biosafety Level: BSL-1.

Bacteria. E. coli HT115(DE3) bacterial strain carrying pGC8. pGC8 is a partial cDNA of him-14 (ZK1127.11) cloned into the Timmons and Fire "double T-7 vector" L4440. The source of the cDNA is Yuji Kohara's clone yk240h12. pGC8 was constructed by inserting the 1.65kb KpnI/SacI fragment of the him-14 cDNA (from base pair 1071 to 192 base pairs beyond the stop codon) into the same sites in L4440. HT115(DE3) carrying pGC8 should be selected in the presence of 50 um/ml tetracyline and 100 um/ml ampicillin. Prior to an actual feeding experiment, it can be grown in liquid in the presence of amp alone (no tet) and then seeded onto NGM plates containing amp and 1 mM IPTG. This technique does not work well if the cells are old; therefore, the strain should be seeded onto IPTG-containing plates from a fresh overnight that was grown from a colony on an amp/tet plate. Biosafety Level: BSL-1. For more info see http://www.wormbook.org/wli/wbg17.1p32/

qSi423 [gld-1p::GFP::H2B::gld-1 3'UTR(FBEa TGT to ACA & FBEa* TGT to ACA)[*rajSi50] + Cbr-unc-119(+)] II. Modification of gld-1 FBEa and FBEa* in gld-1 3'UTR of single-copy insertion transgene.  Qiu et al., in preparation.

Adults generally short, although some can reach near normal length. Slow growth rate. Backing can be loopy, but does not like to back. Strongly hypersensitive to stimuli. Relatively constant spontaneous movement. Some clustering especially in response to stimuli. Mature adults have vulval bump. Most young adults are Egl-c and young embryos can be found on the plate. Some mature adults become moderately Egl-d. Recessive allele. Males are small and slow growing. Mutation is R92C, which is a conserved residue in the 10 amino acid inhibitory domain that normally functions to keep protein kinase A turned off in the absence of cAMP. Population tends to severely crash within 2-3 weeks of starvation.

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.
