Fig. 3From: Metabolic alterations provide insights into Stylosanthes roots responding to phosphorus deficiencyOverview of metabolomic changes in stylo roots at two P treatments. a The volcano diagram of distribution metabolites in stylo roots response to P deficiency. Red circles, green circles and black circles indicate up regulated, down regulated and no response metabolites, respectively. b Category of differentially accumulated metabolites (DAMs) in stylo roots during low P stress. Data are shown as the number of metabolites, DAMs are defined by conforming the variable importance in project (VIP) ≥ 1.0 and -Pi/+Pi ≥2.0 or ≤ 0.5. Up-regulated: -Pi/+Pi ≥2.0, down-regulated: -Pi/+Pi ≤0.5Back to article page
