Hierarchical clustering of differentially expressed genes involved in auxin and cytokinin metabolic or signaling pathways. The pairwise ckII_ckI, dxhII_dxhI, dxhI_ckI, dxhII_ckII, gII_ckII and gII_dxhII indicate the same pairs shown in Fig. 3. The genes shown in the figure is listed in Additional file 8. The color bar from red to blue indicates up-regulated and down-regulated expressions of genes in every pair; the dark color represents high fold change and light color represents fold change; the number in each color cell indicates corresponding value of fold change
