FIG. 7 — Regulation upstream and downstream of ceh-19. Larva hatched from UL2703 animals transgenic for ceh-19b^prom::gfp and subject to RNAi for pha-4 are pharynxless (a1), and although expression in ADF and PHA was maintained, expression in MC was lost (a2). In a wild type background, flp-2^prom::gfp is expressed in MC (b2 and b2 inset) and other neurons (b1/2). In the ceh-19(tm452) background, flp-2^prom::gfp expression was not detected in MCs but was still present in other neurons at the same level as in wild type (c1/2). flp-2^prom::gfp expression was observed in ventral cord motor neurons in the dauer stage only (d1/2) including the axon (d2 inset), here in the wild type. Bars represent 10 µm in a–c, b2 inset and d2 inset, and 25 µm in d. Corresponding images were captured by DIC (a–d1) or epifluorescence (a–d2) microscopy.
