Metabolomics allows comprehensive phenotyping of environmentally modified plant systems. Thus, the metabolomics is an approach for measuring time-related biochemical responses and reactions. A timecourse metabolome analysis was conducted to elucidate the metabolic modulation in a response of plant cells to salt stress. Data mining results suggest that the methylation cycle for the supply of methyl groups, the phenylpropanoid pathway for lignin production, and glycinebetaine biosynthesis are synergetically induced as a short-term response against salt-stress treatment. Metabolomics is emerging as a powerful tool not only for research of system biology but also for substantial equivalence study of genetically modified (GM) crop. GM Chinese cabbage containing the bar gene and 24 non-GM Chinese cabbage varieties were analyzed to evaluate the undesirable changes of the GM crops using metabolic fingerprinting and profiling. The metabolome database was analyzed with PCA. The results clearly demonstrate that the time of sampling affects the metabolome and the metabolic fingerprints show a similar range of natural variability for the GM Chinese cabbage.
