An Agrobacterium-based injection (agroinjection) protocol is presented for the inoculation of foxtail mosaic virus and sugarcane mosaic virusclones into maize seedlings. Inoculation in this manner leads to viral infection, virus-induced gene silencing of marker genes, and viral overexpression of GFP.
