Figure 3. Photomicrographs of GFP or RFP expression driven by promoters derived from the four ABC genes in cluster 6. Promoter-GFP fusion constructs were built as described. Pgp-12 (F22E10.1) showed strong expression in excretory cell in all stages (only adult shown); Pgp-13 (F22E10.2) yielded expression in the adult posterior intestine and amphids; Pgp-14 (F22E10.3) gave expression in the anterior pharynx until half way along the first bulb while Pgp-15 (F22E10.4) was seen in adult head and tail neurons and in the embryo.
