Suppressed Unc. Movement almost WT.

tra-3 suppressed. Viable hermaphrodite. See also CGC 397.

Maternal effect tra-3. Heterozygotes are WT and segregate WT and Dpy. Homozygous tra-3 animals are WT hermaphrodites which segregate abnormal sterile males or intersex.

Dominant suppressor of Unc. Movement almost WT.

Unc-cannot back. Recessive.

Abnormal cell death.

Heterozygotes are weakly Dpy and segregate more weak Dpys, dpy-13 homozygotes and ncl-2 homozygotes. ncl-2 homozygotes are viable, sterile animals with abnormal nucleoli (abnormal refractile appearance by Nomarski). Imperfectly balanced: May Break Down!!

Heterozygotes are WT and segregate WT, Dpy, Vul, and dead eggs. The Dpys throw Dpy males. Maintain by picking WT.

Paralyzed Unc. Small. Recessive. M-MATING-NO SUCCESS.

WT heterozygote, fem-1(e1965) maternal. Segregates WT heterozygotes, WT fem-1 homozygotes that give only fertile female progeny, and UncMor. (Probably has lost mor-2 [Edgley, 4/92]. When confirmed, should be given a new strain name.)

WT phenotype. tra-3 amber mutant carrying homozygous linked amber suppressor.

Phenotypically WT. See also CGC 801. eDf24 = let(e2000).

Stable male/female strain propagated by crossing tra-3(e1767)IV females x tra-3(e1767)IV males. tra-1(e1575) is semi-dominant and transforms both XX and XO into fertile females. Strain contains 4 genotypes: 1) e1575/+; e1767 XX which are fertile females. 2) e1575/+; e1767 XO which are fertile females. 3) e1767 XX which are infertile pseudomales. 4) e1767 XO which are fertile males.

Severe roundheaded Dpy. Almost inviable at 15C.

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.

Heterozygotes are WT and segregate WT, DpyUnc and dead eggs. Maintain by picking WT.

Heterozygotes are WT (somewhat Unc and Egl) and segregate WT, DpyUnc and dead eggs. Maintain by picking WT.

Heterozygotes are WT and segregate WT, DpyUnc and fertile females.

Temperature sensitive Fem. Hermaphrodites at 15C, female at 25C. Maintain at 15C.

Partly or completely suppressed Dpy.

Weak suppression of dpy-20 by sup-23. Medium Dpy.

Weak suppression of dpy-20 by sup-22. Dpy phenotype, but less Dpy than dpy-20 alone.

Suppressed Dpy. e1957 previously called sup-21.

Hets are Unc and segregate Unc, WT hermaphrodites and dead eggs. The WT hermaphrodites segregate only abnormal sterile males or intersexes. Maintain by picking Unc.

Weakest known fem-3 mutation. Viable non-temperature-sensitive self-fertile XX hermaphrodites. e1999 XO males are slightly feminized, sometimes male-fertile. Reference: Hodgkin (1986) PMID: 3770465.

Severely Uncoordinated; Him; feminized at temperatures above 20C. Grow at 15C. Used for generating patroclinous WT males, by exploiting non-disjunction caused by him-8, and dominant sex-linked unc-1.

eIs2137 [sup-7(+) + Dm-hsp::lacZ] IV. lacZ expression induced by heat shock. Limited pattern (the pSHZ1 vector was originally designed for use in Drosophila, not C. elegans, and is not the best vector for expression of lacZ in the worm). This strain has predominantly historical value (as the first C. elegans strain shown to express a foreign gene). eIs2137 transgene is integrated and contains two plasmids: pAST (sup-7 amber suppressor), and pSHZ1 (lacZ driven by Drosophila heat shock promoter (S. Munro)).

Self-fertile intersexual XX animals. Tra-3 masculinized phenotype suppressed by egl-26 mutation. Reference: Hodgkin (1986) PMID: 3770465.

Marginally Unc-no sin wave. Lethargic. Recessive. M-MATING-NO SUCCESS.

Males have abnormal swollen bursa. Hermaphrodites have abnormal swollen vulva.

WT hermaphrodites. Mails have ectopic lateral alae in tail region. Segregates males.

sup-34 is dominant amber suppressor: weak suppression of Unc, medium suppression of Dpy.

Hermaphrodites have an abnormal protrusive vulva. Segregate males with abnormally swollen bursa. Suppressor of certain alleles of certain genes.

Hermaphrodites have an abnormal protrusive vulva. Segregate males with abnormally swollen bursa. ma116 is a weak recessive suppressor of certain alleles of certain genes.

Spongy gut, intestine has foamy look, especially in L4; Temperature sensitive-almost normal at 15C; leaky Eat at 20C; Penetrant and sick Eat at 25C. Unc.

Hermaphrodites segregating males with abnormal ray lineages. Reference: Hodgkin et al. (1989) Genome, 31, 625-637. doi:10.1139/g89-116.

Poorly growing, low self-fertility masculinized XX hermaphrodites. Weak allele of tra-2, partly suppressed to self-fertility by smg (NMD) mutation; permits efficient selection of new feminizing mutations. References: Spence et al. (1990) PMID: 2317869. Zarkower et al. (1994) PMID: 7520378.

Unc. Eat.

Thin, starved, healthy adults. Retain few eggs. Slow irregular pumping at 16, 20, 25C. Unc.
