heSi45 [mcm-4::mCherry + unc-119(+)] IV. This strain contains an S-phase marker that will express mCherry in all cells that undergo cell division, providing a useful alternative to BrdU and EdU staining that is suitable for live imaging.

heIs105 [rps-27::loxP::NLS::mCherry::let858 UTR::loxP::NLS::GFP::let-858 UTR + unc-119(+)] IV. Strain is viable at 15-25 C. heIs105 carries a read-out construct which allows the visualization of the CRE lox mediated recombination by a switch from red to green. Reference: Ruijtenberg S & van den Heuvel S. Cell. 2015 Jul 16;162(2):300-13.

heSi141 [hlh-8(short)::FLAG::CRE::tbb-2 + unc-119(+)] X. Strain is viable at 15-25 C, but non-tissue specific recombination is observed more frequently in other tissues at higher temperatures (25C). Expression of CRE recombinase in the mesoblast lineage driven by the hlh-8 promoter. Reference: Ruijtenberg S & van den Heuvel S. Cell. 2015 Jul 16;162(2):300-13.

heSi142 [elt-2::FLAG::CRE::tbb-2 + unc-119(+)] X. Expression of CRE recombinase in the intestine driven by the elt-2 promoter. Strain is viable at 15-25 C, but non-tissue specific recombination is observed more frequently in other tissues at higher temperatures (25C). 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. heSi141 [hlh-8(short)::FLAG::CRE::tbb-2 + unc-119(+)] X. Maintain at 15-25C. Expression of CRE recombinase in the mesoblast lineage driven by the hlh-8 promoter. heIs105 carries a read-out construct which allows the visualization of the CRE lox mediated recombination in the mesoblast lineage by a switch from red to green. This read-out construct is silenced in the germline. Reference: Ruijtenberg S & van den Heuvel S. Cell. 2015 Jul 16;162(2):300-13.

heSi 143 [rps-27::loxP::mCherry::let-858::fzr-1p::fzr-1::fzr-1 UTR::loxP::GFP::let-858 UTR + unc-119(+)] IV. heSi141 [hlh-8(short)::FLAG::CRE::tbb-2 + unc-119(+)] X. Maintain at 15-25C. Expression of CRE recombinase in the mesoblast lineage driven by the hlh-8 promoter. heSi143 rescues fzr-1(ku298). fzr-1 will be excised upon mesoblast-specific expression of CRE, creating a mesoblast specific mutant of fzr-1. This recombination event can be visualized by a switch from red to green in those cells (the mesoblast) were fzr-1 is lost. Reference: Ruijtenberg S & van den Heuvel S. Cell. 2015 Jul 16;162(2):300-13.

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.

heSi160 [hsp16.48::Cre] X. Transgene allows inducible expression of CRE recombinase. Reference: Ruijtenberg S & van den Heuvel S. Cell. 2015 Jul 16;162(2):300-313. PMID: 26144318.

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.

heSi193 [mcm-4p::CDK sensor::eGFP::tbb- 2 3'UTR + Cbr-unc119(+)] II. This strain carries a GFP S-phase marker expressed in all cells that undergo cell division. Localization of GFP alters between S-phase and interphase. Reference: van Rijnberk LM, et al. PLoS One. 2017 Feb 3;12(2):e0171600.

mjIs145 [mex-5p::GFP::his-58::21UR-1sense::tbb-2 3'UTR] II. Control piRNA sensor strain accompanying SX1316.

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.
