Figure 1. The total number of up- and down-regulated
metabolites in leaves and roots of (a) Geranium pratense, (b)Leucanthemum vulgare, and (c) Ranunculus acris plants
grown in microcosms with different neighbors (PPI) or different soil
legacies (PSI). The number depicted is in comparison to the monoculture
diversity/soil legacy level. Data collected as part of the plant-plant
interaction (PPI) experiment are displayed in light red (up) and dark
red (down). Data collected as part of the plant-soil interaction (PSI)
experiment are displayed in grey (up) and black (down).
