aProtective intervals of 5, 10 and 15 days were tested for N. benthamiana plants, but only interval of 15 days was tested for N. tabacum plants
bNumber of infected/protected plants. The infection was confirmed with Western blotting assay
cControl: The plants were pre-inoculated with empty vector pCAMBIA0390
