CA998 C. elegans ieDf2 [unc-119+]/mIs11 IV. Show Description
mIs11 [myo-2p::GFP + pes-10p::GFP + F22B7.9::GFP]. Heterozygotes are wild-type with dim GFP signal in the pharynx. mIs11 homozygotes are wild-type with bright GFP in the pharynx. ieDf2 homozygotes (non-GFP) develop normally but produce 97.5% inviable embryos and a high frequency of males among the surviving self-progeny. Pick WT with dim GFP+ in pharynx to maintain. mIs11 homozygotes will quickly overtake the population if not selected against. GFP expression in 4-cell embryos, pharyngeal muscle and gut. ieDf2 is a deficiency of zim-1, zim-2, zim-3, and him-8 generated by MosDel, resulting in single-copy insertion of a copy of the C. briggsae unc-119 gene on Chromosome IV. The deletion spans the sequences from the beginning of the zim-1 coding sequence through the ttTi22866 Mos1 insertion site.
