heIs145 [rps-27::loxP::NLS::mCherry::let858 UTR::eft-3::tagBFP::tbb-2 UTR::loxP::NLS::GFP::let-858 UTR + unc-119(+)] IV. Maintain at 15-25C. heIs145 expresses a read-out construct used to visualize CRE activity and specificity, and to test whether CRE expression is likely to induce loss of a gene of interest (tagBFP in this case) in a given tissue. Expression of CRE will result in a change from mCherry to GFP and loss of tagBFP expression in those cells where CRE is active. Reference: Ruijtenberg S & van den Heuvel S. Cell. 2015 Jul 16;162(2):300-13.

heSi149 [myo-3::CRE::tbb-2 3'UTR + unc-119(+)] X. Inserted at ttTi14024. Maintain at 15-25C. Expression of CRE recombinase in differentiated body wall muscle cells driven by the myo-3 promoter. [NOTE: this stock serves as a replacement for SV1461, which was found to be carrying an unidentified red fluorescent transgene in the background.] Reference: Ruijtenberg S & van den Heuvel S. Cell. 2015 Jul 16;162(2):300-13.

heIs105 [rps-27::loxP::NLS::mCherry::let858 UTR::loxP::NLS::GFP::let-858 UTR + unc-119(+)] IV. heSi164 [rps-27::loxN::NLS::mCherry::let858 UTR::swsn-1p::swsn-1::unc-54 UTR::loxN::NLS::GFP::let-858 UTR + unc-119(+)] V. heSi141 [hlh-8(short)::FLAG::CRE::tbb-2 + unc-119(+)] X. Maintain the line at 15C and shift to 25C for mutant analysis. Expression of CRE recombinase in the mesoblast lineage driven by the hlh-8 promoter. heSi164 carries a swsn-1 rescue construct which ensures rescue of the temperature-sensitive swsn-1(os22) mutation. Upon expression of CRE (in this case in the mesoblast lineage) the swsn-1 gene will be excised, creating a mesoblast specific mutant of swsn-1. This recombination event can be visualized by a switch from red to green in those mesoblast cells in which swsn-1 was lost. The animals are healthy at 15C, but embryonic lethal and larval arrested at 23-25C. swsn-1(os22) causes mild overproliferation in the mesoblast lineage. The swsn-1 rescuing transgene is unable to rescue germline development of swsn-1(os22) mutants. Reference: Ruijtenberg S & van den Heuvel S. Cell. 2015 Jul 16;162(2):300-13.

heSi208 [eft- 3p::LoxP::NLS(egl-13)::tagBFP2::tbb-2 UTR::LoxP::NLS(egl-13)::mCherry::tbb-2 3'UTR] V. heSi141 [hlh-8p::CRE] X. Egg laying defective. LoxN sites in the endogenous swsn-4 locus facilitate inducible knockout of swsn-4. he268 he272 homozygotes are Egl since they cannot form a functioning vulva due to swsn-4 inactivated in the mesoderm lineage by hlh-8p::CRE expression.

he314[pie-1p::GLO-ePDZ::mCherry::smu-1::tbb-2 3'UTR] II. e259[eft-3p::PH::eGFP::LOV::tbb-2 3'UTR]) IV. Superficially wild-type. CRISPR/Cas9 was used to create insertion alleles he314 and he259 insertions into N2 background at sites of known MosSCI insertions ttTi5605 and cxTi10816, respectively. ePDZ–LOV system transgenes allow use of blue light to control protein heterodimerization, in this case, membrane recruitment of ePDZ-tagged proteins of interest. Germline-optimized cytosolic ePDZ::mCherry-tagged SMU-1 (GLO-ePDZ::mCherry::SMU-1), and membrane-bound LOV2 domain fused to a pleckstrin-homology domain (PH::eGFP::LOV). GLO-ePDZ::mCherry is a germline-optimized variant coded to be less prone to silencing in the germline. Reference: Fielmich LE, et al. eLife 2018 Aug 15;7:e38198. doi: 10.7554/eLife.38198.

mjIs145 [mex-5p::GFP::his-58::21UR-1sense::tbb-2 3'UTR] II. Control piRNA sensor strain accompanying SX1316. Instead of antisense 21UR-1 target site, this transgene contains the piRNA sequence in sense and histone GFP is not silenced. Reference: Bagijn MP, et al. Science. 2012 Aug 3;337(6094):574-8.

mjIs144 [mex-5p::GFP::his-58::21UR-1target::tbb-2 3'UTR + unc-119(+)] II. piRNA sensor strain. Single copy inserted into ttTi5605 (MosSCI). Superficially wild-type with loss of piRNA sensor silencing in piRNA pathway mutants (e.g. prg-1). GFP is silenced in wild-type, expressed in piRNA pathway mutants and can be used as a simple read-out for piRNA pathway function. Reference: Bagijn MP, et al. Science. 2012 Aug 3;337(6094):574-8.

mjIs588 [mex-5p::GFP::his-58::21UR-1target::tbb-2 3'UTR + unc-119(+)] II. mjIs588 was derived by removing introns 2 and 3 from the construct used to generate the mjIs144 transgene. Single copy inserted into ttTi5605 (MosSCI). Superficially wild-type. mjIs588 GFP is silenced in wild-type animals and de-silenced in hrde-1 mutant animals. Reference: Akay A, et al. Dev Cell. 2017 Aug 7;42(3):241-255.e6.

utdSi51[mex-5p::tomm-20(aa 1-55)::halotag::lov::tbb-2 3’UTR] II. Maintain at 23C and protect from light. Strain is sickly, seems to grow best and lay more eggs at 23C. Upon stimulation with 488nm light, the LOV-ePDZ optogenetic system will recruit mitochondria to the dynein heavy chain in the worm embryo. Embryonic cell divisions can be stopped by if mitochondrial recruitment is stimulated in early development. Room light can also induce mitochondria re-localization and cause infertility; store this strain in the dark. Reference: Fan X, et al. G3 (accepted).

GFP expression in spermatheca. mCherry expression in germline nuclei. UX993 sperm have increased mCherry intensity compared to that of its parent strains. [NOTE: the ltIs37 [pie-1p::mCherry::his-58 + unc-119(+)] IV transgene was previously annotated as itIs37 in this strain. The correct name of the transgene is ltIs37 and not itIs37.]
