Rice Grain Metabolites (IMAGE) RIKEN Caption Rice grain metabolites were annotated in this study. Rice grain metabolites are represented in the simplified metabolic pathway. Node color represents the method used for analysis of that metabolite: gas chromatography-time-of-flight-mass spectrometry (GC-TOF-MS, yellow), capillary electro-phoresis-time-of-flight-mass spectrometry (CE-TOF-MS, blue), liquid chromatography-ion trap-time-of-flight-mass spectrometry (LC-IT-TOF-MS, green) and liquid chromatography-quadrupole-time-of-flight-mass spectrometry (LC-Q-TOF-MS, red). Node shape represents the reliability of metabolite annotation: rectangles indicate metabolites whose structure was identified by comparing their chromatographic behavior and mass spectra with standard compounds, whereas diamonds indicate metabolites whose structure was determined by MS and MS/MS spectral data.
