Hierarchical clustering of genes differentially expressed in Eutrema . Heat map of 2,989 differentially expressed genes generated using complete-linkage clustering of Euclidean distances between log-normalized expression values. Expression levels for genes in each cDNA library are represented as colors ranging from purple (little or no expression) to yellow (abundant expression). On the heat map, expression levels of DEGs in each library are also illustrated by black traces. Clustering at the level of individual libraries is represented by the dendrogram at the top of the heat map and clustering at the level of individual genes is presented at the left of the heat map. All nodes in the dendrogram had bootstrap probability and approximately unbiased p- values greater than 0.99.
