neIs20 [pie-1::3xFLAG::csr-1 + unc-119(+)]. Partially rescues sterility (60% dead embryos). Unknown if unc-119(ed3) is still present in the background. Reference: Claycomb J, et al. 2009 Cell 139:123-34.

neIs20 [pie-1::GFP::csr-1 + unc-119(+)]. Partially rescues sterility (60% dead embryos). Unknown if unc-119(ed3) is still present in the background. Reference: Claycomb J, et al. 2009 Cell 139:123-34.

ltSi240 [csr-1p::csr-1(re-encoded) + Cbr-unc-119(+)] II. The csr-1 coding sequence in the transgene was re-encoded for RNAi-resistance (see Gerson-Gurwitz A, et al. Cell. 2016, Supplementary Figure S3A). [NOTE: it is not known if unc-119(ed3) is still present in the background of this strain.] Derived from strain OD1463; transgene rescues csr-1, so the balancer is not needed to maintain transgenic strain. Reference: Gerson-Gurwitz A, et al. Cell. 2016 Apr 7;165(2):396-409.

Heterozygotes are Unc. csr-1(tm892) homozygotes are non-Unc and Sterile.

Heterozygotes are WT and GFP+. csr-1 homozygotes are basically sterile, but some of them occasionally lay a small number of dead eggs. The fj54 mutation deletes a 524 bp region including half of the second exon, the third exon, and almost all of the fourth exon, causing a frame shift to stop the translation of both PAZ and Piwi domains. The deletion can be checked by PCR with the following primers: AAGAAATACCAATGCGGAGGCA and TTCACGGCTCTTTGCAGTTTCA. Homozygous nT1[qIs51] inviable.

ltSi448 [csr-1p::GFP::csr-1(re-encoded; GFP inserted after aa #5 of isoform b) + Cbr-unc-119(+)] II. ItIs37 [pie-1p::mCherry::his-58 + unc-119(+)] IV. The csr-1 coding sequence in the transgene was re-encoded for RNAi-resistance (see Gerson-Gurwitz A, et al. Cell. 2016, Supplementary Figure S3A). [NOTE: it is not known if unc-119(ed3) is still present in the background of this strain.] Derived from strain OD1764; transgene rescues csr-1, so the balancer is not needed to maintain transgenic strain.

axIs36 [pes-10::GFP]. Heterozygotes are Unc and sensitive to ivermectin. Segregates csr-1 homozygotes (sterile, non-Unc, resisitant to ivermectin), dead embryos, and Unc heterozygotes. Maintain by picking Uncs. Do not distribute this strain; other labs should request it directly from the CGC. Reference: Claycomb JM, et al. Cell. 2009 Oct 2;139(1):123-34.

GFP and 3xFLAG tags inserted into second exon of endgonenous csr-1 locus; tags both isoforms. Reference: Ouyang JPT, et al. Dev Cell. 2019 Sep 23;50(6):716-728.e6. PMID: 31402283

GFP and 3xFLAG tags inserted into first exon of endgonenous csr-1 locus (IV:7957568); specifically tags a-isoform.

Null allele of csr-1 with GFP and 3xFLAG tags inserted into second exon of endgonenous csr-1 locus. tor67 would normally tag both long and short isoforms, but the mg660 allele introduces a stop codon into the first exon so the long isoform is not made and only tagged CSR-1B isoform is produced.
