Differential expression of known defense response genes in compatible and incompatible interactions analysed by hierarchical cluster analysis.

The heat map of the log-fold change values of sample groups R1, r1 and ORF45 at 1 dpi and 3 dpi versus 0 dpi is shown. Unitags matching to twenty four transcripts were selected based on allocation to the gene ontology term “defense response” (GO:0006952). The annotation and the corresponding unigene number are shown on the right. Significance of the pair wise comparisons between R1, r1 and ORF45 sample groups is indicated by * (FDR≤0.05), ** (FDR≤0.01) and *** (FDR≤0.001).
