Figure 2.

Time course of expression of the pTPH-1::GFP reporter. Transgenic worms were photographed at different developmental stages: (A) ~330 minutes-old embryo; (B) Two-fold stage; (C) Two-and-a-half-fold stage; (D) Three-fold stage; and (E) Young adult. The following GFP-positive cells or structures are indicated: pharyngeal muscle (open arrows), NSM cell body (filled triangle), and the major sub-ventral (filled arrow) and dorsal (open triangle) processes. The minor process is not visible in these images. Scale bar represents 20 μm.
