Soybeans are the most popular cultivated crops worldwide. They contain abundant functional components. As part of the research to enhance functional components in soybean plants, soybean adventitious roots were cultured under dark and fluorescent light irradiation conditions and difference in their metabolome was explored using 1H NMR-based metabolomics approach. Results revealed that fluorescent light irradiation increased the biomass of soybean adventitious roots and caused considerable metabolic perturbations. In particular, health-beneficial secondary metabolites such as soyasaponin (3.4-fold), isoflavones (3.9-fold), and coumestrol derivatives (1.3-fold) were accumulated more in soybean adventitious roots grown under fluorescent light irradiation than in those grown under a dark condition due to increased photosynthesis that was evidenced by increased levels of glucose. The present study provides useful information on global metabolite compositions of soybean adventitious roots and their quality improvement by controlling growth conditions to enhance functional potentials of soybeans.

利用荧光照射探索大豆不定根代谢紊乱的代谢组学研究

大豆是全世界最受欢迎的栽培作物。它们包含丰富的功能组件。作为增强大豆植物功能成分的研究的一部分，大豆不定根在黑暗和荧光灯照射条件下进行培养，并使用基于1H NMR的代谢组学方法探索了它们的代谢组差异。结果表明，荧光灯照射增加了大豆不定根的生物量，并引起了相当大的代谢扰动。特别是有益健康的次生代谢产物，例如大豆皂苷（3.4倍），异黄酮（3.9倍）和香豆酚衍生物（1。由于光合作用增加，葡萄糖水平升高证明，在荧光灯照射下生长的大豆不定根中比在黑暗条件下生长的大豆不定根中积累了3倍）。本研究通过控制生长条件以增强大豆的功能潜力，为大豆不定根的全球代谢产物组成及其质量改善提供了有用的信息。
