he25 is temperature sensitive. At 25C: Heterozygotes are WT and segregate WT, DpySteriles (qC1 homozygotes) and Sterile Uncs which have a head region that is broader than the tail region and have no postembryonic cell divisions. At 15C: Heterozygotes are WT and segregate WT, Dpy Steriles (qC1 homozygotes) and cdk-1 homozygotes which are slightly smaller than WT, complete nearly all cell divisions, are sterile and have less germ cells than N2 (sperm are present but no oocytes). Previously called ncc-1(he25).

ceh-6(mg60) is lethal. Maintain by picking WT and check that it throws 1/4 Dpys. mg60 is a 1.3 kb deletion that removes part of the conserved POU-specific domain. PCR with primers PCR6-5 GAA-TTC-ATG-AAA-TCG-GAG-GCG-T (->) and PCR6-3 GTG-AGA-AGT-GAA-GAG-GAT-TGT-A (<-) yields a band of about 1.6 kb instead of 280 bp as in N2. Backcrossed more than 10 times; in addition, the left arm of LG I was recombined with lin-28 to remove the mutator locus.

Heterozygotes are WT and segregate WT, Dpys which give only dead eggs, and dead eggs.

Heterozygotes are Unc-93 and segregate more Unc-93, yDf10 homozygotes (dead eggs) and Unc-93 Dpy-17 homozygotes (young dpy-17 larvae are easily recognizable as abnormal spindle-shaped things). Difficult to maintain and use. yDf10 apparently causes semi-sterility (a second strain constructed by the Mark Edgley at the CGC, yDf10/qC1, exhibits same sterility), and unc-93 is Egl and difficult to mate into. Some Df homozygotes are laid, but most remain inside the mother.

Temperature sensitive. 20% viable at 20C. 80% viable at 15C. XX animals are Dpy. XO animals are nearly WT.

Animals with the Dup are WT. Animals which have lost the Dup are DpyUnc. Maintain by picking WT.

Heterozygotes are DpyUnc and segregate DpyUnc and dead eggs.

Heterozygotes are Unc and segregate Unc, dead eggs and temperature sensitive Dpys. At 15C the y228 homozygotes (derived from heterozygous mothers) are WT and most of their progeny are inviable, dying as arrested embryos or as necrotic Uncoordinated and Constipated L1 larvae; a small number of animals survive and develop into Dpy, Egl adults with a protruding vulva. At 25C the y228 homozygotes (derived from a heterozygous mother) are Dpy and Egl and have a protruding vulva; progeny from these animals are inviable and die as embryos or L1 larvae. See also WBPaper00002302.

Heterozygotes are WT hermphrodites whose progeny include WT hermaphrodites, Dpy hermaphrodites (mnDp66; yDf13 unc-1 dpy-3), WT males and Dpy males.

WT hermaphrodites whose progeny include WT hermaphrodites, Dpy hermaphrodites (mnDp66; unc-1 dpy-3), Unc hermaphrodites (yDp14; unc-1 dpy-3), DpyTra hermaphrodites (mnDp66/yDp14; yDf17), WT males, Unc males, and Dpy males. There are 2 types of WT hermaphrodites in this strain which are indistinguishable unless you score their offspring: mnDp66/yDp14; him-8; yDf17/unc-1 dpy-3 animals will have many WT males progeny; but mnDp66/yDp14; him-8; unc-1 dpy-3 animals will have primarily dpy male progeny [mnDp66/yDp14; unc-1 dpy-3 XO animals are mostly dead, but there are some escapers of lethality]. Maintain by picking L4 WT hermaphrodites and checking for correct segregation of progeny.

yDf20 previously known as y288. Internal deletion. Takes out dpy-3 and lin-32. Heterozygotes are Unc.

Wild type phenotype. In order to identify the correct genotype, JRP93 catttgtctagaactgtcattctgtc; and JRP106 gatctccatttgccggcaaattctcc primers are used to produce a 486 bp amplicon that can be sequenced with either primer for confirmation of the sea-1(y356) lesion (C to T at +97). The sea-1(y356) mutation is covered by the balancer mIn1[dpy-10(e128) mIs14], which is often used in construction of sea-1(y356) containing strains.

Dpy. Throws males. Pick L4 hermaphrodites to maintain. Reference: Yonker SA & Meyer BJ. Development. 2003 Dec;130(26):6519-32. TY3936 was derived in 2002 from TY1932 ncl-1(e1865) unc-36(e251); dpy-21(e428) X N2; cloned WT progeny, let self and picked Dpy animals, cloned and selfed, looked for absence of Unc progeny. TY1932 was frozen into TY collection in 1993; built from other strains derived original CB428 stock obtained & frozen in 1983.

Avoid picking viable aneuploids that often appear larger and longer than wild-type.

syIs44 [hsp-16p::lacI::GFP + lacO(256) + dpy-20(+)] V. Heatshock induces expression of lacI::GFP in the soma, which binds to integrated lacO arrays. lacI::GFP expression is silenced in the germline.
