Characterization of the metabolomic data. (a) Classification of the 1,067 identified metabolites. (b) Classification of the 984 metabolites with low coefficient of variance values within the replicates. (c) PCA analysis of the metabolic samples. (d) The distribution of coefficient of variance values within the replicates for each metabolite (the three replicates of OL20 were used as a representative). (e) The number of differential metabolites between outer layer samples and endosperm samples at each of the four stages. (f) The number of differential metabolites between the stages within each the outer-layer or endosperm tissue.
