Strains carrying this gene

Strain Genotype Description
CB1600 tra-2(f70) II. Transforms XX to males. Variable expression. Masculinized self-fertile hermaphrodite. tra-2(f70) was crossed into the N2 background to construct a dpy-10 tra-2 unc-4 triple mutant, then crossed to remove the flanking dpy and unc (Jonathan Hodgkin).
CB2317 tra-2(e1425) II; sup-5(e1464) III. tra-2 suppressed. Viable hermaphrodite. See also CGC 397. Grow between 22.5C and 24C.
CB2580 tra-2(e1094)/dpy-10(e128) II. Heterozygotes are WT and segregate WT, Dpy and males.
CB2597 tra-2(e1098)/dpy-10(e128) unc-4(e120) II. Heterozygotes are WT and segregate WT, DpyUnc and males. Maintain by picking WT hermaphrodites.
CB2754 tra-2(e1095)/dpy-10(e128) unc-4(e120) II. Heterozygotes are WT and segregate WT, DpyUnc and males. Maintain by picking WT.
CB2830 tra-2(e1209)/dpy-10(e128) unc-4(e120) II. Balances well. Transformer weak. Heterozygotes are WT and segregate WT, DpyUnc and males. Maintain by picking WT.
CB3778 tra-2(e2020) II. Obligate XX female, XO male strain. Maintain by mating. e2020 is a dominant mutation transforming XX into fertile females. XO animals are partly feminized by starvation or elevated temperatures, therefore the strain cannot be grown at 25C.
CB3779 tra-2(e2021) II. tra-2 gain-of-function. Male-female strain. Maintain by mating. References: EMBO J. 2001 Mar 15; 20(6): 1363–1372. Proc Natl Acad Sci U S A. 2004 Aug 24; 101(34): 12549–12554.
CB3967 tra-2(e2046) II. Obligate XX female, XO male strain. Maintain by mating. Viable 15-25C. e2046 is a dominant mutation transforming XX into fertile female; minimal effect on XO.
CB4050 tra-2(e2046e2115) unc-4(e120) II; sup-7(st5) X. Phenotypically wildtype XX hermaphrodite at 20C; poor viability and fertility at 25C. Rare XO animals are hermaphrodite due to suppression of amber mutation e2115 and consequent transformation of XO due to tra-2(e2046) gain-of-function. Reference: Hodgkin & Albertson (1995) PMID: 8647390.
CB4389 tra-2(e1209) II; smg-3(ma117) IV. 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.

Anatomically normal XX females and XX males. Male/female strain with sex determined by an extrachromosomal transgene array carrying fem-1(+). Reference: Strain 16 in Hodgkin (2002) PMID: 12399387.
CB4734 tra-2(e1095)/+ II; fog-2(q71) V; xol-1(y9) X. [XX females and tra-2; fog-2; xol-1 XX males] Obligate male/female strain; maintain by crossing. Anatomically normal XX females and XX males. Male/female XX strain with sex determined by tra-2(+). Reference: Strain 6 in Hodgkin (2002) PMID: 12399387.
CB4905 tra-2(e1403) II. Weak Tra-2 allele, homozygous self-fertile XX. Slightly masculinized hermaphrodite, adults lack tail spike. Reference: Hodgkin & Barnes (1991) PMID: 1684664.
CB4952 tra-2(e2541) II. Hypomorphic allele. Homozygous XX animals are masculinized; have hermaphrodite gonad, abnormal male non-gonadal anatomy; self-fertile.
CB5023 tra-2(e2046e253) unc-4(e120) / + + II; dpy-26(n199) IV. [XO females, dpy-26 XO males] Obligate XO male/female strain, propagate by crossing. Low fertility. Fertile XO females and XO males; inviable XX embryos and larvae. Reference: Strain 7 Hodgkin (2002) PMID: 12399387.

CB5362 tra-2(ar221) II; xol-1(y9) X. ar221 is a tra-2 ts allele. Strain will grow at 15C as Egl hermaphrodites. When grown at 25C, all animals mature into X males, many of which are fertile. Good source of pure XX mating males. ar221 isolated by Jane Hubbard.
DH202 tra-2(b202) II. Temperature sensitive. XX animals are self-fertile hermaphrodites at 15C. XX animals are sterile males at 25C. ts period begins in late embryo.
DZ683 tra-2(ar221) II; xol-1(y9) X; rdIs4. rdIs4 [ehn-3a::Venus(delta)]. Temperature-sensitive. Must be maintained at 15°C to produce progeny.
