Metabolome Analysis System Based on Mass Spectrometry Linked with Plant Metabolite Database

Abstract

This work is a metabolomics-based approach that helps to reveal dynamics of metabolites in cells, and thus to comprehensively understand the whole cellular process of metabolism. We have developed metabolome informatics tools for the purpose of analysis of metabolic profiling data that are obtained from mass spectrometry (MS), such as FT-MS, GC-MS and LC-MS. In addition, we also have designed a database system for searching relationships between metabolites and plant species. This database system is also useful for obtaining information on metabolites and their corresponding species, chemical structure and biological activity. Here, we introduce the present system and database by using a model case of analysis of metabolome data that were obtained from Arabidopsis thaliana.
