arTi461 [rps-27p::GFP(FRT-flexon-FRT)::H2B::unc-54 3'UTR + NeoR] I (-3.80). The first intron of GFP was replaced with a Flexon containing two FRT sites. GFP::H2B is expressed at a high level in lineages where Flp recombiase is expressed with a second transgene. Flexon contains two FRT sites. Reference: Wittes J & Greenwald I. (2024).
