Fig. 5. Expression pattern of MRP-1. (A) Dauer larva formation of unc-31(e169);mrp-1(ut153) was rescued by the mrp-1::GFP fusion gene, showing that it was functional. The means of four plates are shown (21-94 animals/plate). (B) The mrp-1::GFP fusion gene was expressed in various tissues (L1 larva). (C) Expression in seam cells (L2 or L3 larva). (D) Neuronal expression; neurons are indicated by arrowheads. (E) Localization of GFP at the cell membrane. The expression patterns were observed with wild-type animals.
