Integrated network for the association of central (a) and specialized metabolites (b) with seed germination and seed survival percentage. Nodes in the network are color-coded according to their compound classes and shaped according to their specificity (elliptical = central metabolism, rounded rectangles = specialized metabolism, diamond shaped = physiological traits). Relative sizes of nodes correspond to their degree of connectivity. The Spearman rank correlation was employed to compute all pairwise correlations between metabolites across the timeline. Solely significant correlations were chosen to be depicted. A significance level of q < 0.05 and an r-value of >0.5 were considered to be significant.
