level. In plants, these studies emerged after the conclusion of the genome sequencing of Arabidopsis thaliana, Oryza sativa and Populus trichocarpa, as a natural next step approach in the molecular genetics fi eld. These studies became feasible with the technological advances in the mass spectrometry (MS), nuclear magnetic resonance (NMR) and separation methodologies (gas and liquid chromatography).
