From: Comparative transcriptomic analysis of wheat cultivars differing in their resistance to Fusarium head blight infection during grain-filling stages reveals unique defense mechanisms at play

Fig. 3

Transcriptomics of the spikes of three wheat cultivars collected at three different timepoints. A Principal component analysis (PCA) of the transcriptome of all biological samples (3 cultivars × 3 timepoints × 3 biological replicates) based on the normalized counts of all genes. Sample scores for the first and second principal components are plotted, with the explained percentage of variance of PC1 and PC2 indicated along the x and y axes. B and C Percentages of genes significantly differentially expressed in each comparison group. Genes were considered significantly changed if their log2fold change (FC) is greater than 2.5 or less than -2.5, and had an adjusted (Benjamini-Hochberg) p-value < 0.01. *In each comparison, the earliest time point or lowest FHB resistance was used as a reference. D-I Venn diagrams showing the gene overlaps between each comparison. J Hierarchical clustering heatmap comparing the differentially expressed genes in all studied samples
