Figure 6.

Functional annotation and divergence between homologs of five pine and one spruce species. The heat map is based on the 191 putatively orthologous transcripts of six species. The homologs were annotated with Gene Ontology (GO) terms. Colours indicate similarity from yellow (highly similar) to red (weakly similar). The “2× average” is an overall measure of how similar the different species are.
