Effect of StWIPK silencing on spreading of PVY^N-GFP to upper non-inoculated leaves

dpi	Systemically infected plants (%)
	WIPK silenced	Empty vector	Positive control
14	0	14.3	33.3
18	0	14.3	nd
22	85.7	85.7	100

dpi, days post inoculation with PVY^N-GFP; WIPK silenced, six plants were agroinfiltrated with TRV construct for silencing WIPK gene and infected with PVY^N-GFP; Empty vector, six plants were agroinfiltrated with empty TRV construct and infected with PVY^N-GFP; Positive control, three plants were infected with PVY^N-GFP at the same time as WIPK silenced and empty vector plants; nd, not determined at this time point
