Figure 5.

Binary hierarchical dendograms showing the clustering patterns of: (A) TFBS classes that are found in the two monocot (rice, sorghum) members of a given COG but not in the dicot (Arabidopsis) member, and also not among paralogs (lineage-specific), (B) TFBS classes occurring uniquely among rice orthologs (species-specific), (C) TFBS classes occurring uniquely among sorghum orthologs (species-specific), and (D) TFBS classes occurring uniquely among Arabidopsis orthologs (species-specific). The associated transcriptional regulators (TF) and their known biological functions based on the annotation in the plant-specific cis-element (Genomatix, TRANSFAC and PLACE) databases are shown for each TFBS class.
