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.

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.

8xMS2 tag inserted at C-terminus of endogenous C42D4.3 locus. zjuEx2144 [semo-1p::MCP::24×Suntag + col-19p::scFv::sfGFP + ttx-3p::RFP]. Pick ttx-3::RFP+ animals to maintain. MS2-based signal Amplification with Suntag System (MASS). Enhanced MS2-based single-molecule RNA imaging system utilizes Suntag signal amplifier. Suntag is a 19 amino acid protein tag that binds to its specific single-chain variable fragment (scFv) antibody. zjuEx2144 transgene expression provides MS2 coat protein (MCP) fused to 24xSuntag and scFv tagged with GFP. When all the required elements of the MASS (MS2, MCP, 24xSuntag, and scFv antibodies) are present, bright GFP foci will mark the tagged RNA.

Superficially WT. Pick WT to propagate. Throws WT (expressing unc-119::YFP) and DpyUncs. irDp1 is sDp3 carrying a spontaneous integrant of an array carrying unc-119::YFP + unc-32(+) + med-1(+), originally generated in BC4638. irDp1 appears to complement everything sDp3 does and has a similar meiotic transmission frequency of 60%. In another strain, irDp2 was observed to lose ability to complement dpy-17. irDp1 confers a progressive adult egg laying defect (also seen with sDp3).

No obvious phenotype; partial effects on AiY interneuron differentiation; genotyped by PCR that covers the deletion in the ceh-23(ms23) allele.
