Heterozygotes are WT and segregate WT, Unc-36, DpyUncLet and dead eggs. Lethal as sterile adult. Maintain by picking WT. [7/94: No longer throwing eT1 Unc-36's. May have picked up a lethal mutation on one of the eT1 chromosomes. Also, appears to be lethal in mid-late larval stage rather than as adult.]

srl-2 is a recessive suppressor of the s1040 temperature sensitive lethal phenotype. srl-2 has no effect on the Roller phenotype of s1040. (At 20C, s1040 homozygotes arrest development at mid-larval stage. At 15C, s1040 homozygotes are viable weak left-handed rollers.) Maintain at 20C to select for retention of suppressor. Animals at 20C will be DpyUncRol.

srl-1 is a recessive suppressor of the s1040 temperature sensitive lethal phenotype. srl-1 has no effect on the Roller phenotype of s1040. (At 20C, s1040 homozygotes arrest development at mid-larval stage. At 15C, s1040 homozygotes are viable weak left-handed rollers.) Maintain at 20C to select for retention of suppressor. Animals at 20C will be DpyUncRol.

hyEx23 [des-2p::eff-1 + des-2::GFP + rol-6(su1006)]. Over-expression of EFF-1 in the PVDs. Shows reduced branching at L4 to adult stages. Pick GFP+ Rollers to maintain. Reference: Oren-Suissa M, et al. Science. 2010 Jun 4;328(5983):1285-8.

antIs30 [attP-f + Cbr-unc-119(+) + glh-2p::phiC31 + rol-6(partial) + myo-2p::GFP + attP-r] II. antIs30 was inserted into ttTi5605 on LG II using MosSCI. GFP expression in pharynx is very weak (as it is single copy) and is easiest to see during the L1-L3 stages. This strain contains a phiC31 docking site and can be used for precise single-copy integration of transgenes via recombination mediated cassette exchange. The docking site contains inverted phiC31-attP sites flanking phiC31 integrase expressed from the glh-2 germline promoter. Integration constructs need to have inverted phiC31-attB sites that flank the intended sequence to be inserted. Reference: Yang FJ, et al. "phiC31 integrase for recombination mediated single copy insertion and genome manipulation in C. elegans." Genetics 2021.

antIs31 [attP-f + Cbr-unc-119(ant40) + glh-2p::phiC31 + rol-6(partial) + myo-2p::GFP + attP-r] II. Unc. antIS31 has been found to self-excise; check for GFP expression periodically to retain the insertion. GFP expression in pharynx is very weak (as it is in single copy) and is easiest to see during the L1-L3 stages. This strain contains a phiC31 docking site and can be used for precise single-copy integration of transgenes via recombination mediated cassette exchange. The docking site contains inverted phiC31-attP sites flanking phiC31 integrase expressed from the glh-2 germline promoter. Integration constructs need to have inverted phiC31-attB sites that flank the intended sequence to be inserted. antIs31 was derived by CRISPR/Cas9 knockout of Cbr-unc-119 in antIs30 creating ant40, a 691 bp deletion in Cbr-unc-119. Because antIs31 does not rescue unc-119(ed3), BRC566 facilitates the use of Unc-119 rescue as a selection marker for transgene insertions. Reference: Yang FJ, et al. "phiC31 integrase for recombination mediated single copy insertion and genome manipulation in C. elegans." Genetics 2021.
