bqSi471 [hsp-16.41p::FRT::mCherry::his-58::FRT::peel-1 + unc-119(+)] II; bqSi225 [emr-1p::emr-1::mCherry + unc-119(+)] IV. Expression of emr-1p::emr-1::mCherry marker is visible, but faint. Suitable for spatiotemporal cell ablation by crossing with FLP-expressing strains.

Utah natural isolate carrying peel-1(qq99) I. EG4348 was collected by M. Ailion from Salt Lake City, UT. qq99 designates the naturally occurring nonsense mutation in peel-1. Reference: Seidel HS et al. PLoS Biol. 2011 Jul;9(7):e1001115.

oxIs494 [peel-1p::GFP::peel-1 3'UTR + Cbr-unc-119(+)] II. GFP is expressed in the spermatogenic germline. During spermatogenesis, GFP remains in the residual body and is not packaged into sperm. Reference: Seidel HS, et al. PLoS Biol. 2011 Jul;9(7):e1001115.

qqIr7 [peel-1(qq99)] I. oxSi78 [peel-1p::peel-1 (introns included)::GFP::peel-1 3'UTR + Cbr-unc-119(+)] II. Genetic background is a mixture of N2 and wild isolate EG4348. The oxSi78 insertion produces a PEEL-1::GFP translational fusion. PEEL-1::GFP is expressed in the spermatogenic germline and packaged into sperm. PEEL-1::GFP appears to localize to fibrous body-membranous organelles. PEEL-1::GFP does not rescue peel-1(qq99). Reference: Seidel HS, et al. PLoS Biol. 2011 Jul;9(7):e1001115.

oxSi87 [peel-1p::N-terminal 12 amino acids of PEEL-1::GFP::peel-1 3'UTR + Cbr-unc-119(+)] II. GFP is expressed in the spermatogenic germline. During spermatogenesis, GFP is packaged into sperm. Reference: Seidel HS, et al. PLoS Biol. 2011 Jul;9(7):e1001115.

Heat-shock strain can be maintained at 20C without any issues. Degron tag was inserted into the endogenous spe-44 locus, allowing auxin-inducible spermatogenesis arrest and reversible male sterility. Heat-shock-induced expression of PEEL-1 will cause lethality in both sexes. Five generations of lab adaptation following genome editing, all in the CB4856 background. Reference: Kasimatis, KR et al.

Heat-shock strain can be maintained at 20C without any issues. Degron tag was inserted into the endogenous spe-44 locus, allowing auxin-inducible spermatogenesis arrest and reversible male sterility. Heat-shock-induced expression of PEEL-1 will cause lethality in both sexes. fxSi4 was originally inserted in a CB4845 background, but has been sufficiently backcrossed so that PX658 is >98.5% JU2526 genetic background.
