JK5896 C. elegans qSi369 II; unc-119(ed3) III; qSi370 V. Show Description
qSi369 [sygl-1p::24xMS2 loops::3xflag::sygl-1::sygl1 3'UTR]. qSi370 [mex-5p:: MS2 Coat Protein::linker::sfGFP::tbb-2 3' UTR::gpd-2 intergenic sequence::H2B::mCherry::unc-54 3' UTR]. Superficially wild-type with expression of sfGFP and nuclear mCherry in germline. qSi369 and qSi370 constitute an MS2 system which allows live visualization of sygl-1 nascent transcripts in the C. elegans germline in a glp-1 mutant background. qSi370 can be prone to silencing, especially after severe starvation; silencing of GFP or mCherry expression can occur independently of one another. Maintain by picking animals with bright GFP and mCherry expression. Reference: Lee C, et al. Dev Cell. 2019 Aug 19;50(4):426-435.e4.
JK5932 C. elegans sygl-1(q828) I; qSi369 II; qSi370 V. Show Description
qSi369 [sygl-1p::24xMS2 loops::3xflag::sygl-1::sygl1 3'UTR]. qSi370 [mex-5p:: MS2 Coat Protein::linker::sfGFP::tbb-2 3' UTR::gpd-2 intergenic sequence::H2B::mCherry::unc-54 3' UTR]. Superfically wild-type with expression of sfGFP and nuclear mCherry in germline. qSi369 and qSi370 constitute an MS2 system which allows live visualization of sygl-1 nascent transcripts in the C. elegans germline in a glp-1 mutant background.

JK5942 C. elegans fog-3(q873[fog-3::3xFLAG]) I; qSi375 II. Show Description
q873[fog-3(1-262)::GGS::3xFLAG::fog-3(263 Phe)] I. qSi375 [mex-5p::eGFP::linker::his-58::3xboxb::tbb-2 3’UTR] II. The tethering assay allows this strain to be used for determining FOG-3 levels in different genetic backgrounds. Similar fertility to N2 wild type. Reference: Aoki S, et al.

JK5943 C. elegans qSi369 II; glp-1(q224) III/hT2 [bli-4(e937) let-?(q782) qIs48] (I;III); qSi370 V. Show Description
qSi369 [sygl-1p::24xMS2 loops::3xflag::sygl-1::sygl1 3'UTR]. qSi370 [mex-5p:: MS2 Coat Protein::linker::sfGFP::tbb-2 3' UTR::gpd-2 intergenic sequence::H2B::mCherry::unc-54 3' UTR]. Heterozygotes are wild-type with pharyngeal GFP signal, and segregate wild-type GFP+ heterozygotes, non-GFP pharynx q224 homozygotes (Glp sterile at 20-25C) and dead eggs (hT2 homozygotes). All animals are sfGFP + in the germline, with distal and proximal transcription sites in the nucleus. qSi369 and qSi370 constitute an MS2 system which allows live visualization of sygl-1 nascent transcripts in the C. elegans germline in a glp-1 mutant background.
