Strain Genotype Species Description
GS10037 arSi159 [rps-27p::GFP(flexon)::H2B::unc-54 3'UTR + Cbr-unc-119(+)] II; unc-119(ed3) III. C. elegans arSi159 [rps-27p::GFP(flexon)::H2B::unc-54 3'UTR + Cbr-unc-119(+)] II. Inserted into ttTi5605 (II). The first intron of GFP was replaced with a Flexon containing two loxP sites. GFP::H2B is expressed at a high level in lineages where Cre is expressed with a second transgene. Flexon contains two loxP sites. Reference: Wittes J & Greenwald I. (2024). New Flexon-based reagents for tissue-specific Auxin-Inducible Degradation and for characterizing Cre and Flp drivers in C. elegans. microPublication Biology. 10.17912/micropub.biology.001315.

(Strain GS878 does not contain sel(arX) and therefore does not suppress the Egl phenotype at 25C.) See also WBPaper00002966. Do not distribute this strain; other labs should request it from the CGC. This strain cannot be distributed to commercial organizations. This strain cannot be used for any commercial purpose or for work on human subjects.
GS883 dpy-5(e61) sel(ar40) I; unc-32(e189) lin-12(n676n930) III. C. elegans DpyUnc. ar40 is a semi-dominant suppressor. At 25C ar40 suppresses the Egl phenotype of ne676n930. At 15C a high percentage of hermaphrodites have a 0 AC-Egl phenotype. ar40 suppresses proximal mitosis. ar40 does not suppress vulval lineage defects. Do not distribute this strain; other labs should request it from the CGC. This strain cannot be distributed to commercial organizations. This strain cannot be used for any commercial purpose or for work on human subjects.
GS8949 hlh-2(ar623[gfp::hlh-2]) I. C. elegans GFP tag inserted into endogenous hlh-2 locus produces a fully-functional GFP-tagged form of HLH-2. Reference: Attner et al., 2019, Current Biology 29, 1-7.
GS925 let-54(s44) unc-22(s7) IV/nT1 [unc-?(n754) let-?] (IV;V). C. elegans Heterozygotes are Unc and segregate Unc, dead eggs and lethal Twitchers. Lethal early larval (L1-L2). Maintain by picking Unc. Do not distribute this strain; other labs should request it from the CGC. This strain cannot be distributed to commercial organizations. This strain cannot be used for any commercial purpose or for work on human subjects.
GS9402 arTi362 [rps-27p::TIR1(lox2272-flexon-lox2272)::unc-54 3'UTR + HygroR] V. C. elegans arTi362 [rps-27p::TIR1(lox2272-flexon-lox2272)::unc-54 3'UTR + HygroR] V (-19.98). The first intron of TIR1 was replaced with a Flexon containing two lox2272 sites. TIR1 is expressed at a high level in lineages where Cre is expressed. Reference: Wittes J & Greenwald I. (2024).

First intron of GFP is replaced with a Flexon containing two lox2272 sites. GFP::H2B is expressed at a high level in lineages where Cre is expressed with a second transgene. Transgene maps to -12.74 (I). Reference: Wittes J & Greenwald I. (2024).

GS9801 rde-1(ar660) V. C. elegans rde-1(ar660)[rde-1(lox2272-flexon-lox2272)]. 9th intron of rde-1 replaced with a flexon - an artificial exon flanked by artificial introns that each contain a lox2272 site (a flexon). Severely reduces rde-1 function, function can be restored upon excision of the flexon by Cre recombinase. Reference: Shaffer JM & Greenwald I. Proc Natl Acad Sci U S A. 2022 Jan 18;119(3):e2117451119. doi: 10.1073/pnas.2117451119. PMID: 35027456.
