Experiments were ranked according to the proportion of genes in the cluster that were differentially expressed. The most important experiments for each cluster are indicated. *PP, phylogenetic profile. †Low expression in flowers compared to leaves, unstable and moderately unstable transcripts. ‡High expression in roots as compared to a reference made of the whole plant, repressed during shoot development from root explants. PS, plant specific; EBA, Arabidopsis protein with similarity to proteins in other eukaryotes, bacteria and archaea; B, Arabidopsis protein with similarity to proteins in bacteria.
