Dear Colleagues, During recent years, proteomics has become the key to understand physiological processes involving the regulation of expression of many genes from transcription to production of metabolites. Each of these steps is part of the overall mechanisms tightly coordinated to allow organisms to develop or adapt to their environment. Plant proteomics has been dramatically expanding since the beginning of the 2000s thanks to major advances in the development of three technological tools. It started with the sequencing of full genomes and collection of expressed sequence tags or RNAs. The release of the Arabidopsis thaliana genome in 2000 has allowed this plant to become a pioneer model for dicots, and particularly for proteomics studies. More than 650 articles have been published in this field since 2000. A. thaliana has been quickly followed by Brachypodium distachyon as a model for monocots and by plants of agronomical interest such as rice, maize, sugarcane, alfalfa, tomato or flax. Apart from these plants, others for which sequencing data were not available could be studied as well, thanks to the possibility to work with heterologous data. In addition, over the last decade, remarkable technological advances have been achieved due to improvements in mass spectrometry which allowed refining the coverage of total proteomes and sub-proteomes from small amounts of starting material and characterizing post-translational modifications and protein-protein interactions. Furthermore, quantitative proteomics now provides detailed information on organ- and tissue-specific regulatory mechanisms responding to a variety of individual stresses or stress combinations during the plant life cycle. Finally, the development of computational tools allows managing the tremendous amount of data generated by mass spectrometers to deliver relevant biological information. Thus, powerful mass spectrometry-based technologies now provide unprecedented insights into the composition, structure, function and control of the proteome, shedding light on complex biological processes and phenotypes. This Special issue of Proteomes welcomes submissions of original research or review articles aiming at deciphering physiological processes with the use of proteomics tools. Contributions will deal with the dynamics of proteins in their native and modified forms, with the combination of several “omics” approaches in contrasted physiological situations as well as with technical advances in the proteomic field.
