| 中文摘要: |
| 镰孢菌（Fusarium）分泌多种真菌毒素引起的枯萎病、赤霉病、根腐病和穗腐病等植物病害，造成重大的作物生产损失。化学防治是防治镰孢菌的重要手段，但其带来的镰孢菌抗性和生态环境污染等问题，严重制约了农业可持续发展。在病害管理中使用生物防治剂为控制镰孢菌引起的植物病害提供了一种安全、有效和可持续的手段，因此生物防治具有比化学防治更深远的优势。在生物防治剂中使用最广泛的生防微生物是芽孢杆菌属（Bacillus）的成员，其可通过多种机制为植物提供有效控制镰孢菌入侵的方案。芽孢杆菌作为一种优良的生物防治剂已被广泛研究，其可通过生态位竞争、产生抗菌物质、诱导植物系统抗性和塑造根际健康微生物组来拮抗镰孢菌侵染，本文从以上4个方面对芽孢杆菌拮抗镰孢菌的机制进行综述，为农业生产中芽孢杆菌防治镰孢菌病害的研究提供参考。 |
| 英文摘要: |
| A variety of mycotoxins secreted by Fusarium cause plant diseases, such as Fusarium wilt, Fusarium head blight, root rot, and ear rot, resulting in significant crop production losses. Chemical control is an important means to prevent and control Fusarium, but the sustainable development of agriculture is severely restricted due to the problems of Fusarium resistance and environmental pollution. The use of biological control agents in disease management provides an effective, safe, and sustainable means of controlling plant diseases caused by Fusarium, with far-reaching advantages over chemical control. The most widely used organisms in biocontrol agents are members of the genus Bacillus. These species provide plants with an effective regimen for controlling the invasion of infectious agents by a variety of mechanisms. As an excellent biocontrol agent, Bacillus species have been widely studied to antagonize Fusarium infections through niche competition, the production of antimicrobial substances, the induction of plant system resistance, and the development of a healthy rhizosphere microbiome, but these studies have rarely been reviewed. Therefore, this paper summarizes the mechanism whereby Bacillus antagonizes Fusarium from the above four aspects, and provides a reference for research into the prevention of Fusarium disease by Bacillus in agricultural production. |
