Fusarium crown rot (FCR) caused by is a serious threat to wheat production worldwide. This study aimed to assess the effects of strain TM28 isolated from root of against . The strain of TM28 inhibited mycelial growth of by 87.8% at 72 h, its cell free fermentation filtrate had a strong antagonistic effect on mycelial growth and conidial germination of by destroying the integrity of the cell membrane. In the greenhouse, TM28 significantly increased wheat fresh weight and height in the presence of pathogen , it enhanced the antioxidant defense activity and ameliorated the negative effects of , including disease severity and pathogen abundance in the rhizosphere soil, root and stem base of wheat. RNA-seq of under TM28 antagonistic revealed 2,823 differentially expressed genes (DEGs). Most DEGs related to cell wall and cell membrane synthesis were significantly downregulated, the culture filtrate of TM28 affected the pathways of fatty acid synthesis, steroid synthesis, glycolysis, and the citrate acid cycle. TM28 appears to have significant potential in controlling wheat Fusarium crown rot caused by
由[未提及具体病原菌名称]引起的镰刀菌冠腐病对全球小麦生产构成严重威胁。本研究旨在评估从[未提及具体植物名称]根部分离的菌株TM28对[未提及具体病原菌名称]的防治效果。菌株TM28在72小时时对[未提及具体病原菌名称]的菌丝生长抑制率达87.8%,其无细胞发酵滤液通过破坏细胞膜完整性,对[未提及具体病原菌名称]的菌丝生长和分生孢子萌发具有强烈拮抗作用。在温室中,TM28在病原菌[未提及具体病原菌名称]存在的情况下显著增加了小麦的鲜重和株高,增强了抗氧化防御活性,并减轻了[未提及具体病原菌名称]的负面影响,包括根际土壤、小麦根和茎基部的病害严重程度和病原菌数量。对TM28拮抗作用下的[未提及具体病原菌名称]进行RNA测序,发现了2823个差异表达基因(DEGs)。大多数与细胞壁和细胞膜合成相关的DEGs显著下调,TM28的培养滤液影响了脂肪酸合成、类固醇合成、糖酵解和柠檬酸循环途径。TM28在防治由[未提及具体病原菌名称]引起的小麦镰刀菌冠腐病方面似乎具有显著潜力
