Figure 2. HR-MAS 1H-13C HSQC spectrum of 13C-poplar, measured without sample extraction.

Figure 2

Peaks in the spectrum corresponding to metabolites were assigned by 3D HCCH-COSY experiments and matched by standard metabolites and SpinAssign. Ala, Alanine; Glu, Glutamic acid; Phe, Phenylalanine; Gly, Glycine; Ile, Isoleucine; Lys, Lysine; Leu, Leucine; Met, Methionine; Asn, Asparagine; Gln, Glutamine; Arg, Arginine; Ser, Serine; Thr, Threonine; Val, Valine; GABA, γ-amino butyric acid. The arrows show Glucose signals.
