Fig. 2. Expression pattern of the unc-18 promoter. Left-hand images are
Nomarski, and right-hand images are fluorescence. Scale bars: 20 µm.
Animals are pha-1(e2123ts) hermaphrodites at the early L3 stage,
rescued by the extrachromosomal array syEx594 [pha-1,
unc-18::yfp::egl-30]. (A,B) Head. (C,D) Tail. (E,F) Ventral cord. (G,H)
Vulval precursor cells. (I,J) Body-wall muscle. Background fluorescence in H
and J is from neuronal expression of the reporter. AC, anchor cell.
