armEx196 [mex-5p::unc-130::GFP::tbb-2 3'UTR + Cbr-unc-119(+)]. Pick non-Unc to maintain. unc-119(ed3) was crossed into JU258, the niDf199IV deletion was confirmed by PCR, and these Unc worms were used for bombardment. JU258 worms lack specific 21U-RNAs normally present in N2 worms due to deletion of the niDF199 locus. Reference: Cecere G, et al. Mol Cell. 2012 Sep 14;47(5):734-45. Reference: Cecere G, et al.
