COVER RNA silencing of green fluorescent protein (GFP) (center) in leaves from Nicotiana benthamiana is suppressed by an animal (left; B2 protein of flock house virus) or a plant (right) viral suppressor, leading to enhanced GFP expression (lighter green/yellow areas). The role of RNA silencing in defending both plant and animal genomes from invading foreign nucleic acids, the mechanisms underlying RNA silencing, and noncoding RNAs are considered in this special section. 1259 [Image: Shou-Wei Ding]
