Overexpression of the BdCYP711A29 gene increases FHB susceptibility following spray inoculation of F. graminearum. (A) Typical FHB symptoms at 7 and 14 days following spray inoculation of whole spikes of the different lines by the F. graminearum FgDON⁺ strain. Bars equal 1 cm. (B) Percentage of spikelets exhibiting FHB symptoms on at least 50% of the florets of the inoculated spikes at 7 and 14 dpi by the PH-1 strain. Mean of four independent biological replicates (n = 52). Different letters indicate significant differences between conditions; upper case and lower case letters indicate the statistical comparison at 7 and 14 dpi, respectively (p-value < 0.05, Tukey’s test).
