Figure 3

mRNAs differentially expressed across tissues under well-watered and water-deficit stress within a simplified flavonoid biosynthetic pathway. Color codes correspond to those used in Figure 1: Purple (skin-specific), green (pulp-specific), and brown (seed-specific). Letters in parentheses following the Unigene name correspond to the cluster assignment. Intermediates colors indicate genes expressed equally within two tissues. The three genes that lack color-coding were not differentially expressed. Yellow and blue squares indicate mRNAs over-expressed under water-deficit and well-watered tissues, respectively, with in tissue type indicated inside the square (P: pulp; SK: skin; SD: seed).
