Tobacco BY-2 Proteomics
According to the original definition first proposed in 1994 by Marc Wilkins, “PROTEin complement by a genOME”, proteomics is the study of proteins, how they are modified, when and where they are expressed, how they are involved in metabolic pathways and how they interact with each other. A proteome, therefore, is the dynamic protein pool of a biological entity at a given physiological state and thus is directly associated with the phenotype. The advent of complete sequenced eukaryote genomes initiated the postgenomic era. Scientific approaches using this sequence information in their strategy to acquire further insight in living organisms, can be called postgenomics. To differentiate between various approaches, different “-omes” and “-omics” arose. Whereas transcriptomics studies the mRNA content or transcriptome of the genome, proteomics studies the protein complement or proteome and metabolomics studies metabolic products or metabolome present at a defined condition. Subdivision and partial integration of the different -omics and -omes, gave rise to words such as “plastidomics” and “plastidome” or “signalomics” and “signalome”.
