wrdSi23 [eft-3p::TIR1::F2A::mTagBFP2::AID*::NLS::tbb-2 3'UTR] (I:-5.32). rubSi6 [eft-3p::scFv(glo)::GFP(smu-1 introns)::tbb-2 3’UTR] II. rubSi8 [eft-3p::24xGCN4::AID::T2A::tagBFP::H2B::tbb-2 3’UTR *rubSi7]) IV. ltIs44 [pie-1p::mCherry::PH(PLC1delta1) + unc-119(+)] V. SunTag system allows visualization of translation throughout development in real-time. In the absence of translation, GFP signal can be observed in the cytoplasm, nuclei and at epithelial apical membranes.

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.

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.

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.
