Figure 2.

Heat map of metabolic responses to stress conditions in each genotype. Metabolite levels in each stress condition were normalized to that in the WW condition and log₂ transformed. Values are means of up to 12 biological replicates. Red and blue colors represent increase and decrease of metabolites using a false-color scale, respectively. Samples from DS, DS+HS, and WW and HS conditions are arranged from the left. Genotypes are ordered by the grain yield in the corresponding stress condition (smallest at the left) in each year.
