Infection symptoms on Arabidopsis leaves following inoculation with F. graminearum. A) The appearance of representative detached leaves 6 days after spore droplet inoculation. B) Box-plot and dot-plot of 16 infected leaves from 8 different plants of each transgenic line at 7dpi; typical infection symptoms were recorded as the percentage (from 0 to 100) of necrotic area in each leaf. There were no visible differences between infection symptoms on FgRALF-expressing leaves compared with the wild-type (p > 0.05). AtWT (Col-er)- wild-type (Col-er), AtEV- Col-er harbouring an empty vector (EV), AtRALF#1 to #4 are four independent Col-er expressing FgRALF.
