Abstract：
Seaweed extracts have enormous potential as bio-stimulants and demonstrated increased growth and yield in different crops. The presence of physiologically active component stimulate plant stress signaling pathways, enhances growth and productivity, as well as serve as plant defense agents. The seaweed extracts can reduce the use of chemicals that harm the environment for disease management. In the present study, the Sargassum tenerrimum extract treatment was applied, alone and in combination with Sclerotium rolfsii, to Arachis hypogea, to study the differential metabolite expression. The majority of metabolites showed maximum accumulation with Sargassum extract-treated plants compared to fungus-treated plants. The different classes of metabolite compounds like sugars, carboxylic acids, polyols, showed integrated peaks in different treatments of plants. The sugars were higher in Sargassum extract and Sargassum extract + fungus treatments compared to control and fungus treatment, respectively. Interestingly, Sargassum extract + fungus treatment showed maximum accumulation of carboxylic acids. Pathway enrichment analysis showed regulation of different metabolites, highest impact with galactose metabolism pathway, identifying sucrose, myo-inositol, glycerol and fructose. The differential metabolite profiling and pathway analysis of groundnut in response to Sargassum extract and S. rolfsii help in understanding the groundnut- S. rolfsii interactions and the potential role of the Sargassum extract towards these interactions.

摘要：
海藻提取物作为生物刺激剂具有巨大的潜力，并在不同的作物中表现出增加的生长和产量。生理活性成分的存在刺激植物胁迫信号通路，提高增长和生产力，以及担任植物防御特工。海藻提取物可以减少使用危害环境的化学品进行疾病管理。在本研究中,应用了马尾藻提取物治疗，单独和与罗氏菌核结合，到阿achishypogea,研究代谢产物的差异表达。与真菌处理的植物相比，大多数代谢物在马尾藻提取物处理的植物中显示出最大的积累。不同种类的代谢化合物，如糖，羧酸，多元醇在植物的不同处理中显示出整合峰。与对照和真菌处理相比，马尾藻提取物和马尾藻提取物+真菌处理中的糖含量更高，分别。有趣的是,马尾藻提取物+真菌处理显示最大的羧酸积累。途径富集分析显示不同代谢产物的调控,对半乳糖代谢途径影响最大，识别蔗糖，肌醇,甘油和果糖。落花生对Sargassum提取物和S.rolfsii的反应的差异代谢物谱分析和途径分析有助于理解Sargassum提取物对这些相互作用的潜在作用。
