Concepts in Plant Metabolomics

Like genomics, which defines genes in a genome irrespective of functionality, metabolomics profiles all metabolites in a biological sample irrespective of the chemical and physical properties of these molecules. Metabolomics can potentially define cellular processes by providing a measure of the ultimate phenotype of an organism, characterized by the collage of small molecules whose levels of accumulation is altered in response to genetic and environmentally induced changes in gene expression.
