Figure 4From: Preformed expression of defense is a hallmark of partial resistance to rice blast fungal pathogen Magnaporthe oryzaeConstitutive expression of defense systems across rice diversity. The gene expression values before infection of 21 genes of 23 rice cultivars (IND = indica, JTROP = tropical japonica, JTEMP = temperate japonica) were used for hierarchical clustering using GenePattern analysis platform (http://www.broadinstitute.org/cancer/software/genepattern/index.html). Pearson correlation was used as distance and a pairwise complete-linkage as clustering method for both genes and varieties. Bootstrap values were estimated on 1000 permutations by the approximately unbiased method using R package pvclust [57]. Only boostrap values above 95 are shown. Each point represents the mean of three independent experiments. Most of the tropical japonica cultivars show a distinct expression pattern as compared to the other cultivars. The regulons are indicated by roman numbersBack to article page
