hqSi11 [lim-7p::TIR1::mRuby::unc-54 3' UTR + Cbr-unc-119(+)] II. Maintain at 15C. GFP tag and AID* inserted at the 3' end of the endogenous daf-16 gene locus by CRISPR/Cas9 engineering. hqSi11 was generated by replacing the eft-3 promoter of the ieSi57 insertion (oxTi179 site) with the lim-7 promoter using CRISPR/Cas9. This strain can be used for auxin-inducible degradation (AID) of DAF-16 protein in the gonadal sheath. hqSi11 previously known as hq378. Reference: Zhang Y, et al. BioRxiv. 2021 Aug 2. 2007.2031.454567. https://doi.org/10.1101/2021.07.31.454567.

Derived by gamma-irradiation of nEx2309 in parental strain MT23222 and out-crossed five times to MT8189 lin-15B&lin-15A(n765).

Very mildly Dpy Tc1-induced dpy-19 allele. Generates severe Dpys when Tc1 hops out of dpy-19 (doesn't excise cleanly). See also WBPaper00001672. [Some concern whether the Mut phenotype in this strain is actually mut-2 because it showed no transposition of Tc3 or other Tc's besides Tc1. 1/95.]

wdEx353 [Y34D9B.1a::GFP + unc-119(+)]. mig-1::GFP construct made by Marc Vidal's group at Harvard as part of the promoterome project; unc-37 target gene. GFP expression observed in all classes of VNC motor neurons, head & tail neurons, body wall muscle, and intestine. [The strain is described as unc-119 and unc-119(+) as the co-injection marker, but looks to actually be lin-15 (Muv).]

Caenorhabditis inopinata wild isolate; 10x inbred line. Male-Female. Maintain by mating at 25C or above; does not grow well at 20C. See reference for the details d(https://www.nature.com/articles/s41467-018-05712-5). Sibling species of C. elegans. Inbred 10 times, full genome sequence available. Frozen stock recovery is lower efficiency than C. elegans with glycerol; DMSO method works more efficiently. Adult: Large and slender species; ca. 1.5–2.5?mm in length, and individuals may reach up 3.0?mm under optimal culturing conditions. Cuticle is moderate to thick with four-lined lateral field. Deirids on the lateral field, at the level slightly behind the secretory–excretory pore. Lip separated into six sectors, not clearly offset. Six labial sensilla and four cephalic sensilla present. The anterior end of each lip sector very slightly elongated and forming six stomatal flaps. Amphid small, oval pore-like, at the level of the margin of cheilo and gymnostom. Tube-like stoma separated into three parts; short tube-like cheilostom; simple tube-like gymnostom, which is weakly separated into two subsections; and tube-like stegostom covered by pharyngeal sleeve, which is separated into four subsections, prostegostom, mesostegostom, metastegostom, and telostegostom. Metastegostomatal three teeth flap-like. Pharynx separated into four sections; procorpus forming muscular tube, well-developed metacorpus (median bulb); glandular and narrow isthmus; and basal bulb with double haustrulum as the glottoid apparatus. Pharyngo-intestinal valve (cardia) prominent. Nerve ring around the middle of isthmus. Excretory pore located around the margin of isthmus and basal bulb. Female: Gonadal system didelphic, amphidelphic. Anterior and posterior gonadal system are basically symmetric with each other, arranged as ovary, oviduct, spermatheca, spermathecal-uterus junction tissue, uterus and vulva/vagina from distal. Sometimes more than 20 developing eggs are deposited. Tail conical or forming slightly elongated conus with pointed tip. Anus and rectum clearly visible; three (two subventral and one dorsal) rectal glands present. Phasmid forming small pore at ca. 60% of total tail length from anus. Male: Testis single, anteriorly reflexed rightwardly. Vas deferens occupying ca. 1/5 of total gonadal length. Tail enveloped by a closed bursa, supported by nine pairs of bursal rays. Anterior cloacal lip with a rounded and sclerotized appendage and bulge-like appendage between rounded appendage and cloacal opening; a small sensilla-like papilla on the bulge-like appendage. Posterior cloacal lip with tongue-like appendage with two cloacal sensilla. Spicules paired, separate, long and slender with evenly slightly ventrally curved blade and simply pointed tip. Gubernaculum slender, ventrally arcuate with small squared appendage at the distal end in lateral view. Bursa heart-shaped in ventral view, anteriorly closed with serrated edge; serratae obvious in anterior half and vague in posterior half; terminal notch present but unclear. The nine pairs of genital papillae or bursal rays supporting the bursal velum with an arranged (2/1?+?1?+?2?+?3).

Reduced fertility. Reduced long-term survival. Mutator phenotype. DNA damage-induced apoptosis in the germ line. No effect on lifespan or meiotic chromosome disjunction observed.

syIs875 [ins-6p::dYFP + ins-6::mCherry + unc-122p::GFP]. cmk-1(sy2277) is a C-terminal knock-in of mKate2::AID*::FLAG to be used for conditional degradation of CMK-1 protein. sy2277 is a CRISPR-engineered allele generated using the self-excising cassette (SEC) method (Dickinson et al. 2015, Genetics) with the gRNA sequence 5'-AGCGTGAAAAGCGGGTGTAGNGG-3' (note: NGG not included in the gRNA). syIs875 is an integrated transgene that includes a transcriptional and translational reporter for ins-6 and is marked by GFP in the coelomocytes. dYFP signal can be seen in ASI during reproductive growth and in ASJ (strong) and ASI (weaker) during dauer exit.

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.
