Overview of metabolites differing significantly in concentration between Pi‐resistant and Pi‐sensitive maize inbred lines. Histograms show metabolites with significantly altered concentrations between Pi‐resistant and Pi‐sensitive maize inbred lines. The x coordinates indicate metabolites with significantly different concentrations between groups and the y coordinates represent the magnitude of the difference expressed as log₂ (Pi‐resistant maize inbred lines/Pi‐sensitive maize inbred lines). Red bars indicate that the value of the logarithm is >0; cyan bars kindicate that the value of the logarithm is <0. (a) Differences in leaf metabolite concentration between Pi‐sensitive and Pi‐resistant maize inbred lines under Pi‐sufficient conditions (CKS‐L versus CKR‐L). (b) Differences in root metabolite concentrations between Pi‐sensitive and Pi‐resistant maize inbred lines under Pi‐sufficient conditions (CKS‐R versus CKR‐R). (c) Differences in leaf metabolite concentrations between Pi‐resistant and Pi‐sensitive maize inbred lines under Pi‐deficient conditions (TS‐L versus TR‐L). (d) Differences in root metabolite concentrations between Pi‐resistant and Pi‐sensitive maize inbred lines under Pi‐deficient conditions (TS‐R versus TR‐R).
