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).

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.

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.

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). 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.

aeaIs8 [ift-20p::GCaMP6s::3xNLS + lin-15(+)]. hpIs728 [gpc-1p::wCherry + lin-15(+)]. Unc. Nuclear-localized GCaMP6s expressed in ciliated sensory neurons. Cytoplasmic wCherry expression in a subset of neurons. Derived by crossing EG9631 (unc-13) hermaphrodites with ZM10104 (aeaIs8; hpIs728) heterozygous males.

sqIs71 [rgef-1p::GFP + rgef-1p::sid-1]. Pan-neuronal expression of sid-1 driven by the rgef-1 promoter. Expression remains neuron-specific until at least Day 10. Animals respond to feeding RNAi against gfp and neuronal genes snb-1 and unc-13. In contrast, animals are resistant to phenotypes induced by feeding RNAi constructs targeting non-neuronal genes pept-1, unc-112, bli-1 and die-1. Reference: Yang Y, et al. Nat Aging 2024 Jan 4. doi: 10.1038/s43587-023-00548-1. PMID: 38177330. MAH677 effectively replaces strain TU3401 sid-1(pk3321) uIs69 [pCFJ90 (myo-2p::mCherry) + unc-119p::sid-1] V., which was found to show RNAi response in non-neuronal tissues.

armEx196 [mex-5p::unc-130::GFP::tbb-2 3'UTR + Cbr-unc-119(+)]. Pick non-Unc to maintain. unc-119(ed3) was crossed into JU258, the niDf199IV deletion was confirmed by PCR, and these Unc worms were used for bombardment. JU258 worms lack specific 21U-RNAs normally present in N2 worms due to deletion of the niDF199 locus. Reference: Cecere G, et al. Mol Cell. 2012 Sep 14;47(5):734-45. Reference: Cecere G, et al.
