Fig. 4From: Physiological and metabolomics analyses of young and old leaves from wild and cultivated soybean seedlings under low-nitrogen conditionsChanges in the metabolic pathways of young and old leaves in the two soybean genotypes. Suggested changes in the metabolic network in soybean seedlings under LN-stress conditions based on a partial least square-discriminant analysis (PLS-DA). (a) pathway of young leaves; (b) pathway of old leaves. C, cultivar soybean; W, wild soybean; CK, control treatment; LN, low-nitrogen stressBack to article page
