Title | Untargeted metabolome analysis of rice using LC-MS / LC-MSを用いたイネのノンターゲットメタボローム解析 |
Description | Untargeted metabolome analyses of rice using liquid chromatography-mass spectrometry (LC-MS). Two rice cultivars, Koshichikar and Nipponbare, were used.
The information on the peaks detected in rice was available at the Plant Metabolome Repository website (http://metabolites.in/plants).

Title | Preparation of the samples |
Description | The rice seeds were provided by Dr. Keiichi Kanno and Dr. Soichi Kojima (Tohoku University). The rice plants were grown in a greenhouse. The brown rice and the leaf blades were harvested, immediately frozen in liquid nitrogen, and stored at -80C. The sample was homogenated using mortar and pestle under liquid nitrogen into a fine powder and stored at -80C until use. |

Title | Peak detection, alignment and characterization using PowerGetBatch |
Description | The PowerGetBach software (version 0.5.4, http://www.kazusa.or.jp/komics/software/PowerGetBatch) was used for peak detection. In the case of the sample with more than three biological or technical replications, a single parameter setting for high resolution (Method 1-4) was applied for peak detection. In the case of the sample without replications, a single raw datum was processed using three different parameter settings for high resolution (Method 1-4). The data obtained in low-resolution settings (Method 5 and 7) was processed with a single parameter setting. The detailed peak detection parameters for PowerGetBatch are available at the Plant Metabolome Repository website (http://metabolites.in/plants/data/PGB_params.zip).
The detected peaks in the samples with high- and low-resolution analyses and in the mock samples were aligned using PowerGetBatch software for each positive and negative mode. The reproducibly detected peaks in the samples and absent in the mock samples were selected as valid peaks. The selection was performed manually using Microsoft Excel with consideration of the analytical replications of the sample. The most intense and major patterns of the MS2 and MS3 spectra were selected among the alignment results for each peak. Searching candidate compounds in compound databases and prediction of flavonoid aglycones using FlavonoidSearch system for valid peaks were performed as described in the annotation details AM1. |
