Leaf metabolome changes of control plants during development. (A) Partial least squares discriminant analysis (PLS-DA) based on secondary metabolites in control treatments of strawberry leaves at different developmental stages. Triangles 9-week-old leaf metabolomes; squares, 15-week-old; circles 24-week-old. Cross-validation of the model: Q2 = 0.9. (B) Relative abundance of metabolite features with highest variable in projection (VIP) score. White bars abundance in 9-week-old leaves; light-gray bars 15-week-old; dark-gray bars 24-week-old. Bars represent log2 values of means ± SD N = 6. Letters indicate different compounds, for details see Supplementary Table 3.
