Description
RNA2 is a polyprotein movement protein: transports viral genome to neighbouring plant cells directly through plasmosdesmata, without any budding. The movement protein allows efficient cell to cell propagation, by bypassing the host cell wall barrier. It acts by forming a tubular structure at the host plasmodesmata, enlarging it enough to allow free passage of virion capsids
[1, 3, 2].
