adeIs1 [mex-5::spd-1::GFP + unc-119(+)] II. The transgene has been inserted on chromosome II, using the MosSCI technique. This strains expresses the SPD-1 protein fused to GFP in the germline (both males and females) and in embryos. SPD-1 is nucleolar in interphase and labels the central spindle in mitosis and meiosis, later accumulating at the midbody. Reference: Nahaboo W, et al.

Dpy.

Heterozygotes are Unc (shaker; don't move well) and segregate more Shaker Unc, WT and DpyUnc (short and fairly paralyzed). The WT give only males. e1957 previously called sup-21.

In males, P7.p and P8.p fail to fuse with hyp7 at the end of L1. Dominant. him-5 allele is either e1467 or e1490.

Heterozygotes are WT and segregate WT, DpyUncs, and Ste (and Gon) cg121 homozygotes.

DpyUnc.

Medium sized Dpy which curls its tail.

Strain throws WT, DpyUncs and males (and some Lon-don't know where these come from??). Maintain by picking WT. non-Unc non-Dpy males mate at low frequency and will transmit stDp2.

Heterozygotes are WT and segregate WT, Lon males, lots of dead eggs, and Dpys. The Dpys should give all dead embryos at all temperatures. Approximately 60% of these dead embryos make excess mesoderm at the expense of endoderm, due to an E to MS fate transformation. Embryonic lethality is 100% penetrant for or46.

WT strain which segregates WT, Dpy L1 lethals, Lon males and dead eggs. Class II egl-15 mutation.

Heterozygotes are WT and segregate WT, Vuls (bags) and DpyUncs. n2030: Vul; impenetrant Mel (rod-like larval-lethal).

asEx78 [spe-38p::spe-38(cDNA)::spe-38 3'UTR + myo-3p::GFP]. Pick GFP+ to maintain. GFP+ worms are fertile; animals that have lost the array are sterile.

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.

asEx95 [T22B11.1(genomic) + myo-3p::GFP]. Pick GFP+ animals to maintain. as39 is a non-conditional allele of spe-51. Mutant hermaphrodites and males are severely subfertile due to a sperm defect. The extrachromosomal array asEx95 effectively rescues the fertility defect. Him. Reference: Mei X, et al. Curr Biol. 2023 Jul 3;S0960-9822(23)00780-7. doi: 10.1016/j.cub.2023.06.029. PMID: 37453427.

nIs190 [myo-2::GFP]. Him. Heterozygotes are wild-type GFP+ and segregate WT GFP+ heterozygotes, Rol Uncs, dead embryos, and males. nIs190 [myo-2::GFP] integrated in or near mnC1. Approx 0.5% recombination seen between nIs190 and mnC1. Fails to complemement all markers on mnC1.
