Schematic representation of viral particles that can be built using capsid protein of geminiviruses. (A) Wild-type twinned particle. (B) Isometric icosahedral particle. (C) Particle composed of three incomplete icosahedra. This representation is highly simplified for clarity; in reality the two icosahedra of the wild-type particle (A) are twisted to each other by 20° [33].
