DH10 mus-101(b10) I. C. elegans Temperature sensitive. Embryonic lethal. Gonadogenesis abnormal. Recessive. Maternal effect (m,m). Strict. Does not grow at 20C or 25C.
DH117 emb-9(b117) III. C. elegans Temperature sensitive. Semi-dominant. Egg lethal. Not maternal. Will grow at 20C.
DH1300 C. briggsae wild isolate. C. briggsae DH subclone of C. briggsae Zuckerman. This stock was maintained in liquid culture for some number of years, and has acquired mutations that have not been named or mapped. It is Unc, dauer-defective and ts lethal. Previously called C. briggsae BO.
DH1390 rme-2(b1008) IV. C. elegans Low brood size and incompletely penetrant embryonic lethality. Accumulates yolk in the pseudocoelom of adult hermaphrodites. Males are normal.
DH18 zyg-3(b18) II. C. elegans Temperature sensitive. Embryonic lethal. Semi-dominant. Gonadogenesis defective. maternal effect (m,n). Will grow at 20C, but not 25C.
DH187 zyg-7(b187) III. C. elegans Temperature sensitive. Egg lethal. Will grow at 20C, but not 25C. Recessive. Maternal effect (m,n).
DH189 emb-9(b189) III. C. elegans Temperature sensitive. Egg lethal. Maternal effect (m,n). Acc and Gon. Some growth at 20C, but not at 25C.
DH2 zyg-11(b2) II. C. elegans Temperature sensitive. Leaky. Penetrance incomplete. Semi-dominant. Cleavage abnormal. Maternal effect(m,m). Received new stock from Edward Kipreos 7/2003.
DH202 tra-2(b202) II. C. elegans Temperature sensitive. XX animals are self-fertile hermaphrodites at 15C. XX animals are sterile males at 25C. ts period begins in late embryo.
DH235 zyg-8(b235) III. C. elegans Temperature sensitive. Egg lethal. Abnormal first cleavage. Maternal effect (m,n).
DH238 sqt-3(b238) V. C. elegans Temperature sensitive roller. PKA rol-4.
DH244 zyg-9(b244) II. C. elegans Temperature sensitive. Egg lethal. Abnormal first cleavage. Strict maternal effect (m,m). Will grow at 20C.
DH26 rrf-3(b26) II. C. elegans Temperature sensitive. Spermatogenesis defective. Rescue by mating with WT male. Sterile at 25C.
DH261 zyg-10(b261) III. C. elegans Temperature sensitive. Egg lethal. Abnormal first cleavage giving small P1 blastomere. Mutant is ts in late L4-early adult. Partial maternal (m,n).
DH404 unc-63(b404) I. C. elegans Unc. Trichlorfon resistant. Lev resistance leaky.
DH424 C. elegans wild isolate. C. elegans Interfertile with N2. Survives freezing lin liquid nitrogen. Temperature sensitive. Brood size like N2. Generation time like N2. Spontaneous males. Reference WBG 10(2) 140-141. Isolated in El Prieto Canyon, CA. Caenorhabditis elegans wild isolate (Tc1 pattern HCC).
DH84 emb-7(b84) III. C. elegans Temperature sensitive. Egg lethal. Gon phenotype if shifted to 25C early. Maternal effect (m,m).
DH89 zyg-5(b89) II. C. elegans Temperature senstive. No growth at 20C or 25C. Weakly semidominant. Egg lethal.
DR1344 C. elegans wild isolate. C. elegans Reference WBG 10(2) 140-141. Previously called Bergerac LY and Bergerac BO. Caenorhabditis elegans wild isolate. DR subclone of Bergerac BO (Tc1 pattern HCA).
