Strong Muv.

muIs23 [hsp::lin-39 + (pMH86) dpy-20(+)]. Heat-shock inducible lin-39. muIs23 is a spontaneous integrant whose chromosomal location is unknown. [NOTE: This strain was previously described as carrying lin-39(n1760), but it is actually carrying the g to a substitution of mu26. Strain MT7255 has been confirmed to be carrying the a to t substitution of n1760.]

Homozygous viable, gfp expression in intestine, hypodermis, somatic gonad, excretory duct, CAN neuron. Reference: Starich et al. eLife 2020;9:e58619. DOI: https://doi.org/10.7554/eLife.58619

Homozygous lethal deletion balanced by bli-4- and GFP-marked translocation. Heterozygotes are wild-type with pharyngeal GFP signal, and segregate wild-type GFP heterozygotes, arrested hT2 aneuploids, and non-GFP tn1762 homozygotes (dead embryos and L1 larvae). Homozygous hT2[bli-4 let-? qIs48] inviable. Pick wild-type GFP and check for correct segregation of progeny to maintain. tn1762 is a ~9.2 kb deletion within fasn-1, including Exon 2 thru to 57 nt preceding stop codon.

Vulvaless. Strong loss of function allele.

Heterozygotes are WT and segregate WT, DpyUnc and Vul. Pick WT to maintain.

n1760: strong allele of lin-39, vulvaless (n300-like). n945: HSN-. Egl. Coiler.

Small brood size. Semi-sterile. n945: HSN-. Egl. Coiler.

Pick WT to maintain strain. Dp lost at high frequency, usable for mosaic analysis. Animals without the Dp are Unc, Vul and Ncl.

n1761 cuases a partially penetrant "rod-like" larval lethal phenotype (70% at 20C) and a partially penetrant vulvaless phenotype (30% at 20C). It is a splice site defect predicted to eliminate 62 amino acids at the C-terminus.
