Fig. 2From: Virus-based pharmaceutical production in plants: an opportunity to reduce health problems in AfricaSchematic representation of gene of interest overexpression through a- transient expression system using viral RNA silencing suppressor and b- engineered amplicon vectors based on viruses. Genes encoding proteins of interest are represented as pink lines and the viral genome is represented as blue lines. Promoters driving constructs are represented as black arrowsBack to article page
