90% reduced cathepsin D. Cleaner genetic background than PJ1 cad-1(j1); this strain has been outcrossed 2X.

Mild (leaky) allele of cha-1. Has approximately 10% WT ChAT activity. Behaviorally normal-normal growth and development. Males mate. Sensitive to cholinesterase inhibitor aldicarb.

mutEx70 [pmk-1::GFP + rol-6(su1006)]. Rollers. Pick Rollers to maintain. [NOTE: This strain has been incorrectly referred to as RP112 muEx70.] Reference: Mertenskötter A, et al. Cell Stress Chaperones. 2013 May;18(3):293-306.

Fertile Unc-38. sy326 has no phenotype on its own. Suppresses sterility of let-23(sy10) and lin-3(n1058). Sterile in double mutant combination with lfe-1 alleles. Do not distribute this strain; other labs should request it from the CGC.

syIs129 [hemicentin(delta SP)::GFP + unc-119(+)]. Integrant of hemicentin::GFP reporter where the signal has been deleted. 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.

syIs243 [myo-3p::TOM20::mRFP + unc-119(+) + pBS Sk+]. Integrated from PS6053. Strain has been outcrossed, but not known if unc-119 mutation is still present in the background.

syIs390 [15xUAS::?pes-10::GFP::let-858 3'UTR + ttx-3p::RFP + 1kb DNA ladder(NEB)].  GFP cGAL effector.  Weak background fluorescence in some head neurons and the head mesodermal cell.  [NOTE: (03/18/2020) a user has reported syIs390 does not map to LG X] Reference: Wang H, et al. Nat Methods. 2017 Feb;14(2):145-148.

Bacteria. E. coli harboring the plasmid PB255, which uses the lin-31 promoter variant to express the lin-31::VP16 chimeric gene. It is particularly useful for the expression of heterologous genes in the vulval precursor cells. PB255 possesses three main components : an enhancer, a promoter region, a multi-cloning site (MCS), and a 3' UTR derived from the unc-54 gene. [CGC note: The plasmid in this strain was constructed from pBS II KS(+) and is likely Amp-R, but Amp-R has not been confirmed]. Biosafety Level: BSL-1.

fxSi1 [pie-1p::TIR-1::mRuby::unc-54 3' UTR + loxP, I: 2851003] I. fxSi4 [hsp-16.41p::PEEL-1::tbb-2 3'UTR + loxP, II: 8420157] II. fxSi6 [hsp-16.41p::PEEL-1::tbb-2 3' UTR + rpl-28p::mKate2::unc-54 3'UTR + rps-0p::HygR::unc-54 3' UTR, III: 10158855] III. Heat-shock strain can be maintained at 20C without any issues. Degron tag was inserted into the endogenous spe-44 locus, allowing auxin-inducible spermatogenesis arrest and reversible male sterility. Heat-shock-induced expression of PEEL-1 will cause lethality in both sexes. fxSi4 was originally inserted in a CB4845 background, but has been sufficiently backcrossed so that PX658 is >98.5% JU2526 genetic background.

Heterozygotes are WT and segregate WT, hT1 homozygotes (mid-larval lethals), md2415 homozygotes (generally L1 lethals which are almost completely paralyzed and have a coily posture with some head movement), and dead eggs. md2415 has a 2.7 kb deletion in the "unc-13R" region.

e995 homozygotes are superficially wild type in appearance, development, and behavior. e995 is a strong, dominant suppressor of UNC-17 G347R mutations (including e245, e359, p300). e995 corresponds to G84E (gga>>gaa) in the SUP-1 transmembrane domain. PCR method for scoring the e995 mutation in individual worms is presented in the Supporting Information File of Mathews et al., 2012. [Note: although it has been suggested that unc-123 and sup-1 represent the same gene (Walthall et al. 1993), sequence analysis demonstrated no molecular lesions at the sup-1 locus in unc-123 mutants (Mathews et al., 2012). Therefore unc-123 and sup-1 represent different genes.] Reference: Mathews EA, et al. Genetics. 2012 Dec;192(4):1315-25.

sraEx278 [npr-9p::Arch::TagRFP + pBX(pha-1(+))]. Maintain at 25C. This transgenic line expresses TagRFP in AIB and has little response to blue light in the absence of ATR. In the presence of ATR the reversal rate of the animal is decreased upon symmetrical stimulation. Reference: Kocabas A, et al. Nature. 2012 Sep 23. doi: 10.1038/nature11431.

sraEx279 [ttx-3p::Arch::TagRFP + pBX(pha-1(+))]. Maintain at 25C. This transgenic line expresses TagRFP in AIY and has little response to blue light in the absence of ATR. In the presence of ATR the reversal rate of the animal is increased upon symmetrical stimulation, and asymmetrical stimulation causes the worm to turn in the opposite direction to which the head was bent when AIY was excited.

sraEx281 [ttx-3p::chop-2(H134R)::TagRFP + pBX(pha-1(+))]. Maintain at 25C. This transgenic line expresses TagRFP in AIY and has little response to blue light in the absence of ATR. In the presence of ATR the reversal rate of the animal is decreased upon symmetrical stimulation, and asymmetrical stimulation causes the worm to turn in the same direction the head was bent when AIY was excited.
