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).
