Rose mosaic virus is transmitted by which of the following?

Rose mosaic virus is transmitted by which of the following?

• A. Vegetative propagation
• B. Seeds
• C. Pollen
• D. Wind

Answer: (A)

Rose mosaic virus spreads most reliably through the plant material used to make new plants, such as cuttings or grafted tissue. When you clone an infected plant, the virus is already present in the tissues you’re using, so the new plant becomes infected as well. That’s why this route of transmission is the main one for RMV. Seeds, pollen, and wind aren’t typical pathways for RMV. Many rose viruses aren’t seed-transmitted, and RMV specifically moves with the plant tissue rather than through pollen or airborne spread. To minimize spread, propagate only from virus-free stock, and sanitize tools and practices to avoid transferring the virus from infected plants to healthy ones.
