Wild soybeans retain many substances significantly reduced or lost in cultivars during domestication. This study utilized LC-MS to analyze metabolites in the seed coats and embryos of wild and cultivated soybeans. 866 and 815 metabolites were identified in the seed extracts of both soybean types, with 35 and 10 significantly differing metabolites in the seed coat and embryos, respectively. The upregulated metabolites in wild soybeans are linked to plant defense, stress responses, and nitrogen cycling. MALDI-MSI results further elucidated the distribution of these differential metabolites in the cotyledons, hypocotyls, and radicles. In addition to their role in physiological processes like growth and response to environmental stimuli, the prevalent terpenoids, lipids, and flavonoids present in wild soybeans exhibit beneficial bioactivities, including anti-inflammatory, antibacterial, anticancer, and cardiovascular disease prevention properties. These findings underscore the potential of wild soybeans as a valuable resource for enhancing the nutritional and ecological adaptability of cultivated soybeans.
野生大豆保留了许多在驯化过程中栽培品种中显著减少或丧失的物质。本研究利用液相色谱-质谱联用技术分析野生大豆和栽培大豆种皮和胚中的代谢物。在两种大豆类型的种子提取物中分别鉴定出866种和815种代谢物，种皮和胚中分别有35种和10种显著不同的代谢物。野生大豆中上调的代谢物与植物防御、应激反应和氮循环有关。基质辅助激光解吸电离质谱成像结果进一步阐明了这些差异代谢物在子叶、下胚轴和胚根中的分布。除了在生长和对环境刺激的反应等生理过程中发挥作用外，野生大豆中普遍存在的萜类、脂质和黄酮类化合物还具有有益的生物活性，包括抗炎、抗菌、抗癌和预防心血管疾病的特性。这些发现强调了野生大豆作为提高栽培大豆营养和生态适应性的宝贵资源的潜力。
