Expression dynamics and of RsSEPGs during the infection in Brachypodium distachyon and their clustering with expression patterns. Expression levels of each gene during infection (6–32 h post-inoculation) were converted to z-scores and their values were represented as a heatmap. The time point with higher expression levels compared with the others in each gene is shown with yellow color. These RsSEPGs were classified into 6 categories with their expression patterns by the k-means clustering method. The average pattern of each cluster was depicted with colors on the left column.
