VISUALIZATION OF SYSTEMIC RNAI IN C. ELEGANS

"The left image shows an adult C. elegans hermaphrodite expressing GFP transgenes in the pharynx and the nuclei of body-wall muscle cells. The worms to the right express GFP in the pharynx and body-wall, but also express GFP dsRNA exclusively in the pharynx. This autonomous expression of dsRNA causes local and systemic silencing of GFP."
