Comparisons of L693 and L661 in terms of Fusarium head blight (FHB) severity and differentially expressed genes. (A) Photograph of spikes of L693 (left) and L661 (right), grown under greenhouse conditions, 21 days after inoculation with Fusarium graminearum in 2013. For L693, disease symptoms are visible only in the inoculated spikelet, whereas, for L661, they are evident in the entire spike. Bars, 1 cm. (B) Comparison of kernel health between the resistant line L693 (left) and the susceptible line L661 (right) in 2013. The kernels of L693 were fully filled, while those of L661 were shriveled and pinkish. Bars, 1 cm. (C) Multiple comparison of the percentage of diseased spikelets (PDS) in 2013 and 2014. Error bars indicate the standard error of PDS;. Means with the same letter (above error bar) are not significantly different (p > 0.01) and with different letter are significantly different (p ≤ 0.01).
