Quantification of SA and metabolites in hyperaccumulator and nonaccumulator plants

SA, salicyloyl-Glc, and catachol shown as μmol g⁻¹ fresh weight; Phe and cinnamate as nmol g⁻¹ fresh weight. Data represent average (n = 6 individual plants) ± sd.

Phe	54.4 ± 29.1	28.0 ± 7.2	18.1 ± 6.2
Cinnamic acid	52.1 ± 11.6	nda	nd
SA	68.2 ± 11.5	0.13 ± 0.06	0.16 ± 0.08
Salicyloyl-Glc	502.8 ± 30.0	0.58 ± 0.06	0.10 ± 0.02
Catechol	316.2 ± 66.7	6.8 ± 2.2	nd
