Organism
Alfalfa mosaic virus (strain 425 / isolate Madison)
Function
Transports viral genome to neighboring plant cells directly through plasmosdesmata, without any budding. The movement protein allows efficient cell to cell propagation, by bypassing the host cell wall barrier. Acts by forming a tubular structure at the host plasmodesmata, enlarging it enough to allow free passage of virion capsids (By similarity).
Similarity
Belongs to the alfamovirus movement protein family.
