Figure 5From: Chemical and transcriptional responses of Norway spruce genotypes with different susceptibility to Heterobasidion spp. infectionHierarchical clustering of the gene expression of a subset of the sequences assembled as isotigs with a BLASTx homology to genes in the flavonoid or proanthocyanidin biosynthetic pathway. The heatmap goes from blue to red with increasing gene expression. Eight clusters (1-8) were identified as indicated in the figure. Clone number and treatment are indicated in the figure.Back to article page
