White mold is a disease caused by the fungus Sclerotinia sclerotiorum, a highly destructive necrotrophic pathogen that infects soybean crops, among others. Usually, the infection triggers the plant defense system to minimize the damages. However, the effects of the infection on soybean plant metabolism are still unclear. In this work, the metabolic profiles of soybean stems and leaves were accessed using H HR-MAS NMR spectroscopy to identify metabolic changes as a response to S. sclerotiorum infection. This fungus widely affects the central metabolism of soybean plants, and most of the altered metabolites are involved in carbon metabolism, as suggested by the results. Furthermore, the metabolites of central metabolism can be associated with the production of several polyphenolic metabolites. Changes in metabolic profile of leaves indicate systemic effects.
白霉病是由真菌核盘菌引起的一种疾病，该真菌是一种具有高度破坏性的坏死性病原体，除其他作物外，还会感染大豆作物。通常，感染会触发植物防御系统以最大程度地减少损害。但是，感染对大豆植物代谢的影响仍不清楚。在这项工作中，使用 HR-MAS NMR 光谱法来获取大豆茎和叶的代谢谱，以鉴定作为对 S. sclerotiorum 感染的响应的代谢变化。该真菌广泛影响大豆植物的中心代谢，并且如结果所示，大多数改变的代谢物都涉及碳代谢。此外，中心代谢物的代谢物可以与几种多酚代谢物的产生相关。叶片代谢谱的变化表明存在系统性影响。
