Bacteria. Comamonas sp., a bacterium on which C. elegans grows particularly well. Str-R. DA1877 is derived from a bacterium isolated from soil in the Dallas area by Boris Shtonda in 2002. That strain was called H39 in Avery, L, Shtonda, BB (2003), "Food transport in the C elegans pharynx", J Exp Biol 206: 2441-2457. It was identified as genus Comamonas by 16S rDNA sequencing, as described in the paper. L. Avery isolated a spontaneous streptomycin-resistant variant by selecting for growth in LB broth + 200 ug/ml streptomycin sulfate. This strain, when spread on NGMSR plates, gave rise to faster-growing papillae; one of these was streaked out to get DA1877. Biosafety Level: BSL-1.

Bacteria. Str-R. L10 papilla 2; sporulation-defective mutant. This is a low-quality food that is difficult for the worms to eat, and is useful for studies of the effect of food on behavior, physiology, etc. [NOTE: This strain grows better on NGM than on LB media in CGC.] Described in J Exp Biol 206: 2441-2457. Biosafety Level: BSL-1.

Bacteria. Str-R. Streak and maintain on Str+ plates. NGMSR+. Faster growing papilla on NGMSR. [NOTE: This strain grows better on NGM than on LB media in CGC.] Biosafety Level: BSL-1.

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.

Abnormal feeding. Strong relaxation defective. NOTE: This strain is reportedly homozygous for an unknown X-linked unc mutation (10/31/2017).

This endogenous tag on ATG-9 was made from a CRISPR event that used a method described by Dickinson et al. 2015 to efficiently insert GFP in replace of the stop codon of atg-9. Reference: Stavoe AK, et al. Dev Cell. 2016 Jul 25;38(2):171-85.

uonEx1 [unc-54::alpha-synuclein::CFP + unc-54::alpha-synuclein::YFP(Venus)]. Pick fluorescent animals to maintain. No additional transformation marker was included in the array. uonEx1 also known as SC+SV in reference publications. Reduced lifespan (25-35% lower) and reduced pharyngeal pumping rate compared to N2. Novel transgenic strain for monitoring the influence of genetic and/or environmental factors on the extent of alpha-synuclein aggregation using FRET signals. Because the two fusion proteins are separate, FRET is only possible when synuclein aggregation brings a CFP tag very close to a YFP tag within an aggregate. We suggest using this strain in conjunction with the positive control (high FRET) strain DDP2 or with strain NL5901 which shows opposite changes in FRET. References: Nagarajan A, et al. CNS Neurol Disord Drug Targets. 2015 Aug 21. Bodhicharla R, et al. CNS Neurol Disord Drug Targets. 2012 Dec;11(8):965-75.

uonEx2 [unc-54::CFP::YFP(Venus)]. No additional transformation marker was included in the array. uonEx2 also known as CV in reference publications. Lifespan and pharyngeal pumping rates are similar to N2. This is a high-FRET positive control strain for use in conjunction with DDP1. Because the CFP and YFP protein sequences are covalently fused together (and show little evidence of cleavage), FRET should be high and largely invariant since both fluorescent moieties are always in close proximity.

dnSi8 [tdp1::flag::mCherry + Cbr-unc119(+)] inserted into ttTi5605 on LG II. Nuclear-localized mCherry. dnIs22 [sup-46::GFP + unc-119(+)] (site of integration unknown). Strong nuclear-localized GFP expression. [NOTE: This strain was produced by crossing two parental strains carrying strong unc-119 loss of function alleles.

[NOTE: this strain is carrying vab-2(e96), not vab-2(e961)]

Although this strain is maintainable as a homozygote it produces many dead embryos (~80%) and has a low viable brood size (~24 ± 18). Thus, the GFP tag compromises CYB-3 function.

DH subclone of C. briggsae Zuckerman. This stock was maintained in liquid culture for some number of years, and has acquired mutations that have not been named or mapped.

raDf7 suppresses the paralyzed phenotype of unc-112(r367) because the deficiency deletes the dim-1 gene. Reduction or loss of the dim-1 gene product suppresses the unc-112(r367) phenotype. In this strain: Animals homozygous for raDf7 arrest as L1 or L2 larvae; Animals without raDf7 are paralyzed as adults; Animals heterozygous for raDf7 move reasonably well.

edIs6 [unc-119::GFP + rol-6(su1006)] IV. Strong Roller phenotype. Hets are not Rollers (despite the presence of the supposedly dominant su1006 mutation in the array), so heterozygous males mate well. edIs6 is the integration of an array carrying pDP#MMUGF12 and pRF4. pDP#MMUGD12 ia an unc-119::GFP fusion that encodes 101 aa of UNC-119 and was made from the Fire lab vector pPD95.77. pRF4 is the rol-6(su1006) plasmid that gives a Rol phenotype. This strain allows the nervous system to be visualized by GFP fluorescence. GFP expression starts in the early embryo and continues through adulthood in most, if not all, of the nervous system. The expression of a similar lacZ fusion (but carrying a nuclear localizing signal) is described in Genetics 141: 977-988 1995.
