fxSi3 [hsp-16.41p::PEEL-1::tbb-2 3' UTR + rpl-28p::mKate2::unc-54 3'UTR + rps-0p::HygR::unc-54 3' UTR, I:2851003] I. fxSi4 [hsp-16.41p::PEEL-1::tbb-2 3'UTR + loxP, II: 8420157] II. 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.
