The double heterozygote is WT. WT will segregate WT, DpyUncs, mid-larval lethal (hT1 homozygotes) and dead eggs. The DpyUncs are homozygous for zu155 and zu148 and will segregate only dead embryos; the dead embryos have excess hypodermis and muscle and lack germ cells and intestine.

Heterozygotes are WT and segregate WT, Dpys which give only dead eggs, mid-larval lethals (hT1 homozygotes), males and dead eggs. Mutation in pop-1 results in the MS blastomere adopting the fate of the E blastomere. pop-1 mutant embryos have twice the amount of wild type gut and only make anterior pharynx. him-5 is outside the region balanced by hT2.

hmp-2(zu364) homozygotes are 99% embryonic or L1 lethal due to a defect in embryonic body elongation; approximately 1% survive to adult stages. Well balanced by hIn1. Maintain by picking WT.

Heterozygotes are WT and segregate WT, Hmr inviable embyros and Egl Unc. Hmr: Hammerhead - defective hypodermal enclosure, especially in anterior regions; approximately 2% of zu389 embryos enclose normally and are Hmp [Humpback: defective body elongation, abnormal bulges on dorsal side]. See also WBPaper00005031. Received new stock from Allison Lynch in the Hardin lab 3/2009.

zuIs60 [pie-1p::GFP(secreted) + unc-119(+)]. Maternally-expressed secreted GFP fills spaces between embryonic cells, and space between embryo and vitelline membrane. Useful marker for vizualizing intercellular spaces in embryos. Reference: Wehman AM, et al. Curr Biol. 2011 Dec 6;21(23):1951-9.

Temperature sensitive. At restrictive temperature (26C), efl-1 produces dead eggs with a Mex phenotype. Two ts periods: 1) prior to L4 results in sterility, 2) after L4 results in a maternal-effect embryonic lethal phenotype.

Heterozygotes are WT and segregate WT, Uncs, Vul and dead eggs. Uncs are homozygous for zu148 and will segregate only dead embryos; the dead embryos will have no morphogenesis and will lack germ cells and intestine.

At 20C or 25C, heterozygotes are WT and segregate WT, UncDaf and dead eggs. At 15C, heterozygotes are WT and segregate WT, Uncs and dead eggs.

Heterozygotes are WT and segregate WT, DpyUnc and early larval lethals. Received new stock 5/98. Check carefully for segregation of Dpy Unc progeny; dpy-13 can be lost easily. Do not distribute this strain; other labs should request it from the CGC.

Heterozygotes are WT and segregate WT, Females which lack a pharynx (arrest as embryos or L1) and Sterile Unc Rollers. Do not distribute this strain; other labs should request it from the CGC. See also WBPaper00003770.

Heterozygotes are WT and segregate WT, Dpys, and Uncs which make excess sperm, are elongated and tend to coil, are slow and have poor backing. Do not distribute this strain; other labs should request it from the CGC.

qIs55 [hnd-1::GFP + unc-4(+)] integrated on IV or V. Do not distribute this strain; other labs should request it from the CGC.

M04B2.1 Throws Steriles and GFP(+) nT1 heterozygotes and dead eggs. The nT1 chromosome is apparently homozygous lethal since Vul worms are not seen. For some reason, crosses with this nT1[qIs51] chromosome generate an excess of male progeny. Do not distribute this strain; other labs should request it from the CGC.

Rollers. About 15% have a one-armed gonad or are WP. Do not distribute this strain; other labs should request it from the CGC.

T05C12.6, T05C12.7. Heterozygotes are WT and GFP+ in the pharynx. mIn1[mIs14 dpy-10(e128)] homozygotes are Dpy and GFP+ in the pharynx. Homozygous mig-5&cct-1(ok280) worms arrest at about L2/L3.

To maintain, check individual fertile worms for both Sep and Fog offspring. sep-1 homozygotes are sterile at 20C and 25C (Sterile and Unc at 25C), and mostly normal at 15C. fog-1; fbf-1 fbf-2 homozygotes have small germ lines and are often Muv. Best to maintain at 25C for scoring. Do not distribute this strain; other labs should request it from the CGC.

qIs56 [lag-2p::GFP + unc-119(+)] V. qEx557 [hsp-16p::ceh-22b + ttx-3::DsRed]. Him. Pick DsRed+ animals to maintain qEx557 array. Heat-shock can be used to drive the ectopic expression of CEH-22B (derived from Fire Lab vector pPD49.78). LAG-2::GFP is expressed the embryo, nerve cord, Z1/Z4, and DTCs. Reference: Lam N. et al. Curr Biol. 2006 Feb 7;16(3):287-95. doi: 10.1016/j.cub.2005.12.015. PMID: 16461282

Slow growing and throw about 10% dead embryos. q783 is a deletion of the first 4 exons on the larp-1 gene. NOTE: this strain is carrying mut-16(mg461) in the background; It is unknown if mg461 is homozygous in this strain. See JK4545 for a replacement larp-1(q783) strain. mut-16 can be detected using primer1 CCCGCCGATACAGAAACTAA, primer 2 AATATTCGATCGGCAAGCAG for genotyping. The wild-type locus will yield a 824bp PCR product, whereas mg461 will yield a 373bp product. Do not distribute this strain; other labs should request it directly from the CGC.

Heterozygotes are WT, GFP+ in the pharynx and segregate WT (GFP+ in the pharynx), dead eggs (hT2 homozygotes) and non-GFP gld-1(q93) homozygotes with masculinized germlines. Some heterozygotes will also have a masculinized germline. Maintain by picking GFP worms and checking for correct segregation, since the hT2 balancer is lost at low frequencies. gld-1(q93) was isolated as a dominant suppressor of fem-1(hc17).

qIs24 [lag-2p::GFP]. Maintain by picking individual animals with green DTCs and green pharynx and scoring offspring for Fems and Fbfs. fem-3 is not well balanced by qIs24. fbf-1 fbf-2 homozygotes are germline proliferation defective and make only sperm. fem-3 homozygotes make only oocytes. fbf-1 fbf-3; fem-3 proliferates more than fbf-1 fbf-2 and makes only oocytes; also Muv. qIs24 contains lag-2::GFP; Distal Tip Cells are green; homozygotes are Rollers and heterozygotes Roll weakly. mIn1 is Dpy and GFP+ in the pharynx. Do not distribute this strain; other labs should request it from the CGC.

Pick GFP+ heterozygotes to maintain. Segregates fertile GFP+ heterozygotes, non-GFP homozygous mutants (Gld; form germline tumors), very rare GFP+ homozygous hT2, and dead eggs. gld-1(q361) is a missense allele but phenotypically null, which allows the detection of gld-1 mRNA and protein by single molecule FISH or antibody staining.
