Metabolomics: Enabling Systems-Level Phenotyping in Rice Functional Genomics

2007 Springer Science+Business Media, LLC. All rights reserved. Metabolomics is considered to be one of the major phenotyping approaches in plant research. Because of its ability to provide a comprehensive biochemical phenotyping that can assist in the identification of novel gene functions, and because of the proven close relationship between metabolites, metabolic network, and cellular network and thus systems biology, metabolomics is poised to contribute extensively to functional genomics. As programs are developed that take advantage of the combined strengths of various analytical technologies, and as bioinformatic and central database resources for metabolomics become more available, we can expect that metabolomics will contribute substantially to the rice functional genomics initiative. Although only a few rice metabolomics studies have been reported so far, a number of rice metabolomic projects are currently being conducted in many laboratories worldwide, and we expect the number of reported studies to increase exponentially in the near future.
