Fig. 3From: Ionomic and metabolic responses to neutral salt or alkaline salt stresses in maize (Zea mays L.) seedlingsChanges in the metabolism pathways in the roots of maize seedlings after 15-d treatment with alkaline salt stress. Suggested changes in the metabolic network in maize seedlings under alkali stress. Data obtained by PLS-DA. Red boxes refer to significantly enhanced metabolites, whereas those in green boxes were significantly reduced (P < 0.01)Back to article page
