title: Proteomics: a powerful tool in the post-genomic era.
abstract: Genomics is having a profound impact on biological research, including photosynthesis investigations. Genomes of many photosynthetic organisms have been sequenced. The information about ALL genes that govern and execute photoautotrophic metabolism provides many opportunities to understand genome function and details of known and uncharted pathways. Proteomics, analysis of the protein complement of the genome, is a powerful tool in understanding which proteins are present in a particular tissue under given conditions. Proteomics also allows us to estimate relative levels of proteins and to determine post-translational modifications of the gene products. In this minireview, we discuss the technology and its applications in plant sciences.
