par-2(it315) exhibits a weak maternal effect sterility, suggesting that the tag reduces the protein activity. Note, however, that double homozygous mutants of it315 with pkc-3(it309) or par-6(it310) exhibited partially penetrant and variable maternal effect lethality and maternal effect sterility that was stronger than it315 alone. Thus, although the GFP tags on pkc-3 and par-6 show no effect in an otherwise wild-type background, they do seem to somewhat compromise the activity of the proteins they tag. Made in N2 background.

Superficially wild-type. Made in N2 background.

Heterozygotes are Unc and segregate Unc, RolPar (adult homozygotes lay eggs that don't hatch) and dead eggs. nT1[unc-?(n754) let-?] is dominant Unc and recessive lethal. Strict maternal effect. sc8 previously called rol-4(sc8).

Heterozygotes are WT and segregate WT, DpyUnc and Unc-4 which give dead eggs. Maintain by picking WT. Strict maternal effect. it9 was previously called mel-21(it9).

mel-8 is a maternal effect lethal. WT heterozygotes segregate WT; mel-8 unc-4 homozygotes that lay eggs that don't hatch, and mnC1 dpy-10 unc-52 homozygotes (paralyzed Dpys). Some F2 mel homozygotes hatch, but such escapers arrest at L1 or L2. Previously called mel-6(it27).

The origin of this strain is KR1082 via CB51. KR1082 was maintained on plates for a period of approximately two years. After this time, DNA was made and the Tc1 pattern examined. The number of Tc1s found in KR1787 was greater than that found in KR1082. Perhaps as many as 30 additional Tc1s were visible in excess of those normally seen in N2 strains.

Animals with the duplication are Unc. Animals which have lost the duplications are DpyUnc and arrest at mid-larval development. Maintain by picking Unc non-Dpy. Previously called let-354(h79).

kasEx80 [oig-1p::tagRFP::unc-54 3'UTR + pha-1(+)]. Maintain at 25C to maintain array. RFP driven by minimal oig-1 promoter for expression in VD-type GABAergic motor neurons. This construct uses the minimal length of promoter containing overlapping LIN-39 and UNC-30 ChIp-seq peaks (deletion of the single LIN-39 binding site within it compromised GABAergic motor neuron expression). Whereas other available oig-1 constructs are expressed ectopically in cholinergic motor neurons in unc-3 mutants, expression of this construct remains exclusively in GABAergic motor neurons.

kasIs9 [snb-1p::(delta)C9 ubi + myo-2::GFP]. The transgene has the snb-1 promoter followed by nanoluciferase sequence and unc-54 3'UTR. Reference: https://pubmed.ncbi.nlm.nih.gov/34654821/

kasEx147 [oig-1p(1.6kb)::GFP::unc-54 3'UTR + myo-2p::GFP]. Pick worms with GFP+ pharynx to maintain array. Unc. 1.6kb cis-regulatory region (-2.6-1.0kb) upstream of oig-1 was fused to GFP with the unc-54 3'UTR. oig-1 uses mulitple cis-regulatory regions to achieve different expression patterns in motor neurons; this construct drives expression specifically in cholinergic motor neurons. Construct was injected into N2 worms. Reference: Feng W, et al. Elife. 2020 Jan 3;9. pii: e50065. doi: 10.7554/eLife.50065.

kasEx149 [oig-1p(2.6kb_del)::GFP::unc-54 3'UTR + myo-2p::GFP]. Pick worms with GFP+ pharynx to maintain array. Unc. 2.6kb cis-regulatory region with 200bp deletion removing predicted LIN-39 binding site upstream of oig-1 was fused to GFP. Expression of oig-1::GFP in GABAergic motor neurons is been abolished; expression was observed specifically in cholinergic motor neurons of the ventral nerve cord. Reference: Feng W, et al. Elife. 2020 Jan 3;9. pii: e50065. doi: 10.7554/eLife.50065.
