The top row of the table indicates which viruses were present in the inoculum tissue used for aphid inoculation, and the succeeding rows indicate the transmission rate of each virus in each treatment in terms of number of plants infected/number of plants inoculated (white row) and in percentage of plants infected (gray row).
