| Abstract | As the final downstream product of the genome, the plant metabolome is a highly complex, dynamic assortment of primary and secondary compounds. Although technological platforms to study genomes, transcriptomes and even proteomes are presently available, methods to pursue genuine metabolomics have not yet been developed due to the extensive chemical diversity of plant primary and secondary metabolites. No single analytical method can accurately survey the entire metabolome. However, recent technical, chemometric and bioinformatic advances promise to enhance our global understanding of plant metabolism. Separation-based mass spectrometry (MS) approaches, such as gas (GC) or liquid chromatography (LC)-MS, are relatively inexpensive, highly sensitive and provide excellent identifying capacity. However, Fourier transform-ion cyclotron resonance (FT-ICR)-MS is better suited for rapid, high-throughput applications and is currently the most sensitive method available. Unlike MS-based analyses, nuclear magnetic resonance (NMR) spectroscopy provides a large amount of information regarding molecular structure, and novel software innovations have facilitated the unequivocal identification and absolute quantification of compounds within composite samples. Due to the size and complexity of metabolomics datasets, numerous chemometric methods are used to extract and display systematic variation. Coupled with pattern recognition techniques and plant-specific metabolite databases, broad-scope metabolite analyses have emerged as functional genomics tools for novel gene discovery and functional characterization. In this review, key metabolomics technologies are compared and the applications of FT-ICR-MS and NMR to the study of benzylisoquinoline alkaloid metabolism in opium poppy are discussed. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
