Figure 4

The effect of water deficit on ABA metabolism. The color in each box next to the enzyme name represents the ratio of the log2 of the transcript abundance of WD/WW. The upper set of boxes is for Cabernet Sauvignon and the lower set is for Chardonnay at various times pre- or post-véraison as indicated by the key. Heatmaps of the time series represent changes in gene expression levels as indicated by the color legend above. The high and low light arrows show the direction of the pathway under each condition, respectively. a) BHASE (β-carotene hydroxylase), 1617541_s_at; b) ABA1 (zeaxanthin epoxidase), 1606913_at; c) NPQ1 (violaxanthin de-epoxidase), 1615888_at; d) CCD1 (9,10 [9',10']carotenoid cleavage dioxygenase), 1610743_s_at; e) NCED (nine-cis-epoxycarotenoid dioxygenase), 1607029_at; f) NCED, 1610455_at; g) NCED, 1608022_at; h) ABA2 (xanthoxin dehydrogenase), 1606686_at; i) ABAHASE ((+)-abscisic acid 8'-hydroxylase), 1621989_at; j) UGT (UDP-glucose glucosyltransferase), 1621418_at; k) UGT, 1621051_at; l) UGT, 1615714_at; m) 1618155_at; n) BGL1 (β-glucosidase), 1622281_at; o) BGL1, 1608202_at; p) BGL1, 1620808_at; q) BGL1, 1620679_at.
