Fig. 5: Diurnal changes in exudate profiles.
From: The core metabolome and root exudation dynamics of three phylogenetically distinct plant species
a Principal component analysis of A. thaliana (yellows), B. distachyon (reds) and M. truncatula (blues) exudate metabolites at the end of day (EOD) and end of night (EON). Percent of metabolites that are significantly different between species at end of day b, end of night c, and for each species between end of day and night d. Colored by high (dark green) to low (light green) intensity. e Fold difference of metabolites significantly increased in end of day vs. end of night A. thaliana (yellow, top graph), in B. distachyon (red), M. truncatula (blue), or in two species (bottom graph, indicated in subtitles). One representative experiment out of three total is displayed. Compounds are grouped by decreasing fold change within one group and are colored by class: orange: Amino acids, peptides and derivatives, purple: carbohydrates and conjugates, green: lipids and lipid-like, blue: nucleosides, nucleotides and derivatives, red: organic acids, black: other. #: EOD and/or EON value below detection limit. *: and/or isomers. Data are averages ± S.E. N = 4–8 jars per timepoint with 3–5 plants each for a–e, n = 74 metabolites in total for a–d, Anova/Tukey test, p < 0.05 for significant differences in e. Details of this dataset are given in Supplementary Fig. 5.
