Wheat Spikes (IMAGE)
Caption
The PH-1-ΔFgtpp1-1 mutant did not show an observable virulence defect when wheat spikes were inoculated using the top-inoculation method. Yellow arrows indicate inoculation points. Wheat spikes infected with either the ΔFgtpp1-1 mutant (PH-1-ΔFgtpp1-1) or wild-type F. graminearum PH-1 strain showed similar disease symptoms (left). The number of diseased spikelets throughout the time courses for the ΔFgtpp1-1 mutant and wild-type F. graminearum PH-1 were similar (middle), and the area under the disease progress curve (AUDPC) values calculated for the mutant and wild type did not reveal significant differences (right). Violin plots show distribution of the AUDPC values (black dots), average AUDPC values, and confidence intervals (rectangles) for each fungal strain. The statistical analysis (t test) included pooled data from three independent replicates. Each replicate consisted of 12 plants, where 6 plants (one spike per plant) were inoculated with either ΔFgtpp1-1 mutant or wild-type F. graminearum PH-1 strains (the total number of plants inoculated was 17 and 18 for the ΔFgtpp1-1 mutant and wild-type F. graminearum PH-1 strain, respectively).
