Virulence of virus‐free and Fusarium graminearum virus 1 (FgV1)‐infected F. graminearum strains [wild‐type (WT) and FgHal2 gene deletion, complementation and over‐expression mutants] on wheat. (A) Representative wheat heads 14 days after they were inoculated with conidia. (B) The percentage of symptomatic wheat spikelets 14 days after inoculation. Means and standard deviations were calculated from independent repeated experiments. Error bars indicate standard deviation. Bars with different letters are significantly different (P < 0.05).
