ozEx76 [cdk-4p::CDK-4::GFP + sur-5::DsRed)]. Maintain by picking DsRed+. ozEx76 is unstable; strain exhibits high levels of lethality and sterilty. ~10% of progeny are fertile. Reference: Fox PM, et al. Development. 2011 Jun;138(11):2223-34.

maIs103[rnr::GFP unc-36(+)]. Heterozygotes produce 1/4 thin, sterile, uncoordinated animals that fail to undergo postembryonic somatic cell divisions. rnr::GFP is expressed during S-phase in heterozygous animals. rnr::GFP expression is not detected in heDf1 animals. Although the map position of maIs103 has not been determined conclusively, maIs103 genetically behaves linked to cdk-4. Maintain by picking several single animals and scoring for 1/4 mutant progeny.

maIs103[rnr::GFP unc-36(+)] X. Heterozygotes produce 1/4 thin, sterile, uncoordinated animals that fail to undergo postembryonic somatic cell divisions. rnr::GFP is expressed during S-phase in heterozygous animals. rnr::GFP expression is not detected in heDf1 animals. Although the map position of maIs103 has not been determined conclusively, maIs103 genetically behaves linked to cdk-4. Maintain by picking several single animals and scoring for 1/4 mutant progeny.

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.

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.

heIs9 [myo-3p::cyd-1 + myo-3p::cdk-4::Venus + myo-3p::GFP::H2B] IV. Expression of CYD-1, CDK-4::VENUS, and GFP::H2B in body wall muscles (BWM). Over-expression of tagged CYD-1 and tagged CDK-4 from integrated transgene causes incidental extra BWM nuclei. Expression levels are higher that those from heIs12 in SV860.

heIs12 [myo-3p::cyd-1 + myo-3p::cdk-4::Venus + myo-3p::GFP::H2B]. Expression of CYD-1, CDK-4::VENUS, and GFP::H2B in body wall muscles (BWM). Over-expression of tagged CYD-1 and tagged CDK-4 from integrated transgene causes incidental extra BWM nuclei. Expression levels are lower that those from heIs9 in SV857.
