Metabolite Content in the Phloem Sap Exudate of Rosette Leaves from NHL26-Overexpressing Lines.

Mean metabolite content, in relative units in the phloem sap exudate of p35:NHL-overexpressing plants and wild-type (WT) plants, collected by EDTA-facilitated exudation. The data points and error bars represent the mean and se (n = 3) of the metabolite content, per unit fresh weight measured in pmol/mg fresh weight, normalized to the overall content of the phloem exudate. AA, amino acids; OA, organic acids; RU, relative units. Asterisks indicate values significantly different in a t test (*P < 0.05; **P < 0.01; ***P < 0.001).

(A) Sugar content. The inset indicates the total sugar content.

(B) Amino acid content. The inset indicates the total amino acid content.

(C) Other metabolites, including organic acid content. The inset indicates the total organic acid content.
