title: Metabolic profiling using Fourier-transform ion-cyclotron-resonance mass spectrometry.
abstract: With the aid of the extreme resolving power of Fourier-transform ion-cyclotron-resonance mass spectrometry (FT-ICR/MS), we have developed a metabolomics platform for high-throughput metabolic profiling and metabolite candidate identification integrating a data-processing system, the Dr.DMASS program ( http://kanaya.naist.jp/DrDMASS/ ), and a metabolite-species database, KNApSAcK ( http://kanaya.aist-nara.ac.jp/KNApSAcK/ ). We discuss the potential of this FT-ICR/MS-based metabolic profiling scheme as a general metabolomics tool by clarification of plant metabolic disorders and specific metabolite accumulation patterns caused by herbicidal enzyme inhibitors.
