Figure 3.

Annotated dendrogram obtained by clustering term-occurrence values relative to each gene. The corresponding clustergram is shown in Figure 2. Genes are arranged according to patterns of term occurrence. Distances between nodes of the tree diagram indicate the degree of association between genes or groups of genes. A subset of representative terms used in the analysis was chosen to annotate this list of genes. Shades of yellow indicate different levels of term occurrence in abstracts. Table 1 lists the gene abbreviations used.
