Strains carrying this gene

Strain Genotype Description
HL2000 +/szT1 [lon-2(e678)] I; nhr-25(jm2389)/szT1 X. Heterozygotes are WT and segregate WT, dead eggs, and Lon males. nhr-25 is homozygous embryonic lethal.
HR1184 +/szT1 [lon-2(e678)] I; nmy-1(sb115) dpy-8(e130)/szT1 X. Heterozygotes are WT and segregate WT, Dpy Uncish with occasional Rol (nmy-1 dpy-8), Lon males, and dead eggs. nmy-1 homozygotes have a low brood size and are slow growing. sb115 is a null, truncation allele.
HR890 +/szT1 [lon-2(e678)] I; syDf1/szT1 X. Heterozygotes are Lon and segregate Lon and dead eggs.
JK323 qDf3/szT1 [lon-2(e678)] I; +/szT1 X. Heterozygotes are WT and grow slowly. Segregates Lon males. Do not grow at 25C. Do not distribute this strain; other labs should request it from the CGC. This strain cannot be distributed to commercial organizations. This strain cannot be used for any commercial purpose or for work on human subjects.
JM69 dpy-5(e61) unc-13(e1091)/szT1 [lon-2(e678)] I; elt-2(ca15)/szT1 X. Heterozygotes are WT and segregate WT, Lon males and dead eggs.
KM48 +/szT1 [lon-2(e678)] I; cdk-4(gv3)/szT1 X. 745 bp deletion of cdk-4 from intron I to exon3 removing putative ATP binding domain and catalytic residues. Most homozygous animals arrest at L2 due to absence of most or all postembryonic somatic cell divisions. Some germline proliferation resulting in slightly elongated gonad.
KR1115 dpy-5(e61) unc-13(e450) hDf9/szT1 [lon-2(e678)] I; +/szT1 X. Wild-type phenotype, Him. Segregates wild-type, Lon-2 males and two classes of arrested embryos (dpy-5 unc-13 hDf9 homozygotes and szT1 aneuploids). Lon males are fertile, carrying hDf9 and both szT1 half translocations (arising by meiotic nondisjunction of normal X chromosome). Maintain by picking wild-type and checking for correct segregation of progeny. This strain was generated by the Genetic Toolkit project, which should be acknowledged in any publications resulting from its use: The Genetic Toolkit is funded by the NIH National Center for Research Resources (NCRR) (USA) to Ann M. Rose, David L. Baillie, and Donald L. Riddle. Report all experimental results to Ann Rose.

KR1537 dpy-5(e61) let-540(h884) unc-13(e450)/szT1 [lon-2(e678) unc-29(e403)] I; +/szT1 X. Heterozygote is wild-type, segregating WT, late-larval arresting DpyUncs, szT1 homozygotes (lethal, probably embryonic), and aneuploids (dead eggs). Pick WT and check for correct segregation of progeny to maintain stock. Note that some lethals recovered by hT1 are expected to be outside the szT1 crossover suppression boundary and these strains may thus produce DpyUnc progeny. unc-29 marker may also cross away from szT1(I).
KR1588 dpy-5(e61) let-539(h938) unc-13(e450)/szT1 [lon-2(e678) unc-29(e403)] I; +/szT1 X. Heterozygotes are WT and segregate WT, arrested DpyUncs, Lon males and large number of aneuploid progeny (arrested embyros or larvae). Note that unc-29 is outside the recombination-suppressed region of szT1 and may cross off resulting in Unc-29 progeny. Pick WT and check for correct segregation of progeny to maintain. This strain was generated by the Genetic Toolkit project, which should be acknowledged in any publications resulting from its use: The Genetic Toolkit is funded by the NIH National Center for Research Resources (NCRR) (USA) to Ann M. Rose, David L. Baillie, and Donald L. Riddle. Report all experimental results to Ann Rose.

KR1598 dpy-5(e61) unc-13(e450) let-538(h990)/szT1 [lon-2(e678) unc-29(e403)] I; +/szT1 X. Wild-type phenotype. Segregates WT, sterile adult DpyUncs, Lon-2 males (szT1 hemizygotes) and a large number of arrested aneuploid progeny (mostly dead eggs). Pick WT and check for correct segregation of progeny to maintain. Note that unc-29 on szT1(I) lies in the non-balanced region and may recombine onto the normal LG I.
KR1692 dpy-5(e61) unc-13(e450) let-535(h993)/szT1 [lon-2(e678) unc-29(e403)] I; +/szT1 X. Wild-type phenotype. Segregates WT, mid-larval arrested DpyUncs, Lon-2 males (szT1 hemizygotes) and a large number of arrested aneuploid progeny (mostly dead eggs).

SD1135 +/szT1 [lon-2(e678)] I; dlg-1(ok318)/szT1 X.
SP413 unc-7(e139) lon-2(e678) X. Lon and Unc.
SP875 lon-2(e678) dpy-3(e27) X.
SV411 heDf1 maIs103/lon-2(e678) unc-9(e101) X. maIs103[rnr::GFP unc-36(+)] X. The heDf1 deletion includes cdk-4. Heterozygotes produce 1/4 thin, sterile, uncoordinated animals that fail to undergo postembryonic somatic cell divisions. heDf1 mutants are of L1 size, smaller than cdk-4 mutants. lon-2 and unc-9 do not exactly balance heDf1, but unc-9 is pretty close. It should also be possible to follow the heterozygotes by looking at the GFP. Despite trying, unable to separate the maIs integration from heDf1 or the other cdk-4 alleles. By maintaining animals with GFP (visible especially in early animals and in eggs) you should be able to maintain heDf1. rnr::GFP is expressed during S-phase in heterozygous animals. rnr::GFP expression is not detected in heDf1 animals. maIs103 is tightly linked to heDf1. Maintain by picking several single animals and scoring for 1/4 mutant progeny.
