Fig. 2 — B. distachyon was grown for 3 weeks in sterile, nonsterile, and sucrose-supplemented conditions followed by exudate collection in the same 0.5 strength MS medium. Fresh weight of root and shoot a and root/shoot ratio b at 3 weeks. Data are averages ± SEM, n = 15 individual plants, *=p < 0.05, ***=p < 0.0005 (two-sided t-test). Root morphology of plants is described in Supplementary Fig. 4. c Principal component analysis of exudate profiles. d Metabolite classes detected in the entire dataset, and classes enriched (bold, blue) or depleted (italic, red) in sucrose-supplemented or nonsterile conditions compared to sterile conditions (Fishers exact test). Values are in percent of total number of metabolites (n = 109 metabolites of 4–5 jars with 3 plants per growth condition). One representative experiment out of three is displayed.
