Fig. 8. Confocal fluorescence micrograph of an adult worm showing Pplc-3::GFP expression in the intestine. Strong expression of Pplc-3::GFP was also detected in the spermatheca and gonadal sheath as described previously (Yin et al., 2004; arrows) and the isthmus of the pharynx (arrowhead). Similar observations were made in two independent worms strains. Bar, 50 um.
