Fig. 5. (A) Hox/PBC-binding sites in the egl-18 and elt-6 genomic
region and GFP reporter constructs. Open reading frames of egl-18 and
elt-6 are indicated by black and gray boxes, respectively. Introns
and 5' and 3' UTRs are indicated by lines. Triangles indicate
consensus Hox/PBC-binding sites, two of which in the second intron of
egl-18 are labeled sites 1 and 2. (B) Alignment of C.
elegans site 1 and the corresponding C. briggsae sequence. The
region corresponding to C. elegans site 2 is not conserved in C.
briggsae.
