dhIs59 [Topo::daf-9::GFP + lin-15(+)]. Perinuclear expression in a ventral pair of bilateral neurons identified as the IL1Vs or URAVs in the anterior ganglia. By mid-L2, expression in the cytoplasm of the hypodermis, the syncitial epidermis, but absent from midline, epidermal seam cells. Levels peak around the L2 molt and diminish during L4. In some cases, transient expression seen in the L3 vulval blast cells. Also expressed within the hermaphrodite spermatheca starting in late L4 larvae and continuing eve in old adults. In males, expression in IL1V/URAVs and hypodermis but not somatic gonad. In dauer larvae, strong expression in IL1V/URAV and specifically extends into axonal but not dendritic processes. In post-dauer stages, expression in a pattern similar to reproductively growing animals, except expression is absent in the hypodermis. Grow at 20C. May still contain lin-15(n765) mutation in the background.

mfIs42 [Cel-sid-2(+) + Cel-myo-2::dsRed]. Maintain at 15C. Feminization is partially-penetrant at 15C; most hermaphrodites are somewhat self-fertile and can lay small broods. Can be maintained by crossing with male siblings. Feminized C. briggsae strain made susceptible to RNAi knock-down by feeding dsRNA due to the transgenic expression of C. elegans SID-2.

The strain was generated by using 5' attgttgctggcatcaaaaa crRNA for C-terminal lpin-1 editing and using dpy-10 editing as a co-conversion marker, followed by outcrossing twice to ABR lab stock of N2 to eliminate the dpy-10 co-conversion marker.

Transgene rescues spe-19(eb52) sperm activation defect. GFP+ hermaphrodites are fertile. non-GFP hermaphrodites are sterile. All males are fertile.

Him. Temperature-sensitive sterile. Small brood size even at permissive temperatures; pick fertile animals and maintain at 15C. Worms lacking spe-45 function produce morphologically normal and motile sperm that cannot fuse with oocytes despite direct contact in the reproductive tract. spe-45 hermaphrodites and males are subfertile at 16C and sterile at 25C.

aeaIs10 [rgef-1p::GCaMP6s::3xNLS + lin-15(+)]. Worms express GCaMP6s in all neuronal nuclei.

Neodiplogasteridae: Pristionchus Iheritieri, Maupas, 1919. Isolated in Ontario, Canada. [9/98: Ralf Sommer has found this strain to be hermaphroditic. He had successful matings between AF8130 and PS312 Pristionchus pacificus, indicating that AF8130 is probably P. pacificus.]

Heterozygotes are WT and segregate WT, UncBli, and Steriles which have an everted vulva. ar104 previously called evl-22 and mat-2.

zhIs38 [let-23::GFP + unc-119(+)] IV. zhIs38 resuces let-23(sy1) and recapitulates LET-23 antibody staining in VPCs. let-23::GFP transgene is expressed at levels similar to endogenous LET-23. Reference: Haag A, et al. PLoS Genet. 2014 May 1;10(5):e1004341.

zhEx11[apr-1(+) + sur-5::GFP]. Unc. Segregates dead eggs that have lost the rescuing array.

rmIs133 [unc-54p::Q40::YFP]. AM141 animals show a soluble Q40::YFP distribution in body wall muscle cells immediately after hatching. As these worms age the rapid formation of foci is observed. When they reach adulthood, AM141 animals show an entirely Q40::YFP aggregated phenotype.

qIs51 [myo-2p::GFP + pes-10p::GFP + F22B7.9p::GFP]. Heterozygotes are wild-type GFP+ and segregate non-GFP ok421 homozygotes, wild-type GFP+ heterozygotes, and arrested nT1[qIs51] aneuploids. Pick wild-type GFP+ and check for correct segregation of progeny to maintain. Received new stock 12/02.

meIs1 [pie-1p::GFP::lacI + unc-119(+)]. meIs4 [lac-O + rol-6(su1006) + lacO] IV. Pick Rol worms to maintain. This strain throws both Rol and non-Rol worms, seemingly due to random silencing of rol-6(su1006) in the lacO array, meIs4. The strain expresses GFP::LacI in the gonad and embryos that is observed as foci (of lacO target) and nuclear haze. The expression level of GFP::LacI occasionally becomes low possibly due to random silencing of meIs1. If this happens, heat shock the strain at 25°C for 3 days, and pick a clone that exhibits bright GFP signals. Even at the highest expression level, GFP signal is too weak to detect with a fluorescent dissection microscope, and it is necessary to use a regular compound fluorescent microscope with an oil immersion 60X or 100X objective. The NA of the objective should be higher than 1.4. Reference: Bilgir C, et al. G3 (Bethesda). 2013 Mar 11. pii: g3.112.005165v1.

Heterozygotes are WT and GFP+. Segregate syp-3(me42) homozygotes that are non-GFP and lay mostly dead eggs; these mutants form abnormal synaptonemal complex formation during meiosis. Homozygous hT2[bli-4 let-? qIs48] animals are inviable.
