Figure 5.

Heat maps showing the log₂ fold changes in metabolite levels under control conditions in the DS compared to the WS for flag leaves (A) and panicles (B). Only metabolites with a significant change in at least three out of the eight cultivars are displayed. The level of significance is indicated by asterisks (* p < 0.05; ** p < 0.01; *** p < 0.001) and the log₂ fold change is represented by the indicated color code. Blue indicates a lower metabolite level in the DS compared to the WS, and red, a higher level. Metabolites are listed alphabetically within the metabolite classes (compare Supplementary Table S2). Cultivars are sorted alphabetically within the respective O. sativa subspecies indica (1–4) and japonica (5–8).
