Answer:

All viruses that spread within their host tissues (systemically) can be transmitted by grafting branches or buds from diseased plants on healthy plants. Natural grafting and transmission are possible by root grafts and with parasitic dodder (Cuscuta species). Vegetative propagation often spreads plant viruses.
