Proteomics derives from 'genomics' and 'proteins' is the study of protein pathways, expression, function and structure. The science of proteomics is less advanced in plants than equivalent studies in prokaryotes, simple eukaryotes and several mammalian systems. Many aspects of plant proteomics can benefit from more intensive research in proteomics to the solution of practical problems in metabolism pathways, senescence and plants response to stress conditions which will give added dimensions to the already recognized importance of research in plant proteomics. The application of proteomic approaches to plant:" entails comprehensive identification of proteins, characterization and function of each protein and analysis of protein regulation.
