Maintain by picking WT. Segregates Muv Unc (let-60 unc-31 homozygotes), wild-type heterozygotes and dead eggs. Reference: Moghal N, Sternberg PW. Development. 2003 Jan;130(1):57-69.

Heterozygotes are weak Muv and segregate weak Muv, Muv Twitchers, and Dpy Vuls whose progeny are larval lethal. sy100 is a dominant negative allele of let-60. n1046 is a gain-of-function allele of let-60. Do not distribute this strain; other labs should request it from the CGC.

Heterozygotes are GFP+. mIn1 homozygotes are Dpy and GFP+. let-23(sy12) homozygotes are non-GFP.

Heterozygotes are non-Dpy Vul and segregate non-Dpy Vul, DpyVul whose progeny are dead, and dead eggs. sy100 is dominant Vul and recessive Lethal with maternal rescue: homozygotes from heterozygous mothers grow to adulthood and become a bag of dead larvae. sy100 is not 100% penetrant. Do not distribute this strain; other labs should request it from the CGC.

Unc. Suppresses the Vul phenotypes of let-23(lf) mutants. Do not distribute this strain; other labs should request it from the CGC.

syIs187 [pes-10::7XTCF-mCherry-let-858(3'UTR) + unc-119(+)]. Cherry POPTOP. POPTOP expression is best visualized using the mCherry/Texas Red filter. POPTOP transgenes display background expression. POPFOP(sy974) is the control plasmid with mutated binding sites. Analysis of POPFOP should always be used to subtract background expression. Do not distribute this strain; other labs should request it from the CGC.

Heterozygotes are Vul (97% Egl). Segregates dead eggs. sy99 homozygotes are lethal. Do not distribute this strain; other labs should request it from the CGC.

syIs197 [hs::LIN-3c(cDNA) + myo-2p::DsRed + pha-1(+)]. Him. Maintain at 15C. To induce LIN-3/EGF expression, heat shock at 33C for 30min (water bath) and let animals recover at least 1hr from the behavioral effects of the heat shock. Heat shock-induced LIN-3 should inhibit feeding, locomotion and sensory responses for several hours. For details on EGF-induced quiescence, see Nature Neuroscience 10, 1300 - 1307 (2007). PS5970 is identical to PS5628 as described in Development 137, 2065-2074 (2010) except that it has been outcrossed to remove accumulating suppressors.

Grows slowly with low brood numbers. Sluggish worms.
