bpIs131 [sepa-1p::sepa-1::GFP + unc-76(+)]. Him. SEPA-1::GFP aggregates form in a temporal pattern.

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.

Temperature-sensitive allele of cyd-1. Phenotypically wild-type at 15C. At 25C, approximately one-third of q626 hermaphrodites were missing one distal tip cell (DTC) and approximately one-half of q626 males were missing the linker cell (LC). q626 also feminizes the XO gonad. q626 affects the production of SGP daughters in both sexes. There is also a maternal component since the mutant phenotype is almost fully penetrant in offspring of homozygous mothers, but less penetrant in offspring of heterozygous mothers. Reference: Tilmann C & Kimble J. Dev Cell. 2005 Oct;9(4):489-99.

Heterozygotes are WT with major GFP signal in pharynx. Segregates WT GFP+, Dpy GFP+ (mIn1 homozygotes) and GFP- gld-3 homozygotes. Do not distribute this strain; other labs should request it from the CGC.

qIs74 [sys-1p::GFP::pop-1 + unc-119(+)]. Probably on LG X. May have unc-119 in background. Throws 30% males. Do not distribute this strain; other labs should request it from the CGC.

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

Heterozygotes are wild-type and segregate wild-type heterozygotes, glp-1(q35) homozygotes (Muv steriles), eT1 homozygotes (Unc-36), and males. glp-1(q35) has a semi-dominant multi-vulva phenotype as well as the loss-of-function Glp phenotype (sterility and embryonic lethality). The q35 mutation is a nonsense mutation that eliminates 122 C-terminal amino acids including a PEST sequence. The C terminus was thought to contain a negative regulatory domain that inactivates glp-1 in the VPCs; the inappropriate glp-1(q35) activity can substitute for lin-12 vulval fate determination.
