Clustering dendrogram for phenotype category "Endospores". Phylogenetic clustering dendrogram of the 50 most discriminative positive domains associated with the phenotype category "Endospores" (see also section "Methods"). Clusters with a maximum linkage branch length of 70% (Matlab^® 'dendrogram' default threshold) are assigned unique colors. In the dendrogram a cluster of protein families associated with sporulation can directly be identified (colored green). This cluster also contains several uncharacterized domain families ("DUFs").
