The implementation of mass spectrometry (MS) for peptides (MS) and amino acids (tandem MS or MS/MS) analysis allowed the identification of hundreds of proteins in single experiments. A number of different strategies are current available for sample fractioning and purification, proteins identification, quantification, post-translational modifications (PTM) and interaction analyses. In this way, the proteomics open up new perspectives in plant biology with emphasis on studies of genetic variability, physiological stresses and plant development.
