Dendrogram for clustering earthworm samples using array expression data of 301 significant genes. Centered correlation and average linkage were chosen in the clustering algorithm. Treatment: Worm #1 to 6 = 6-d control, #7 to 12 = 6-d treated, #13 to 18 = 13-d control, #19 to 24 = 13-d treated. Left panel: PMT350 dataset; Right panel: PMT450 dataset.
