Tree view and functional categories of hierarchically clustered genes during Ca - Fusarium incompatible interaction. Tree view represents the expression patterns of genes displaying significant regulation in response to Fusarium infection at 24 hours post pathogen inoculation. Genes were organized using hierarchical clustering and displayed, including Cluster1 that represents the significantly repressed genes and Cluster2 that corresponds to significantly induced genes. Each row represents a single gene and each column corresponds to log2 (ratio) of an experimental sample. Black indicates the median level of expression, red indicates greater expression than the median and green less expression. Pie below each cluster shows the distribution of clustered genes into various functional categories. Detailed information on genes within each cluster can be found in additional file 6.
