Clusters of transcripts based on patterns of differential expression. A representative fragment of clustering analysis showing the behaviour of each gene relative to the others in rosettes and roots of cfbp1 and cyfbp mutants (left). The figure shows up-regulated genes in rosettes of cfbp1 and cyfbp, down-regulated genes in cfbp1 roots; and up- or down-regulated genes in cyfbp roots. Differentially expressed transcripts were clustered, using the k-means method. Six Clusters were created (Clusters a-f, right side), with Clusters a and d comprising up-regulated genes in rosettes and roots of cyfbp, respectively; and Clusters f and c comprising down-regulated genes. Clusters e and b comprising up- and down-regulated genes in cfbp1 rosettes. Clusters c and a comprising up- and down-regulated genes in cfbp1 roots, respectively. The x-axis represents (1) cfbp1 rosettes (2) cfbp1 roots (3) cyfbp rosettes, and (4) cyfbp roots. The y-axis represents the expression level
