Abstract

Among plant disease management strategies, biological control is a sustainable alternative to the use of chemicals for the control of vascular wilt caused by Fusarium oxysporum. Fusarium wilt is the most devastating disease affecting a wide variety of plants. Bacillus species are the most widely used biological control candidates for the control of these fungal diseases. This review describes the pathogenicity of F. oxysporum, its virulence mechanisms, and host plant–pathogen interactions. The control means deployed by Bacillus species inhibit or kill these phytopathogens. Bacillus spp. produce a wide range of secondary metabolites, including volatile and non-volatile organic compounds. Biocontrol potential is achieved through direct antimicrobial activity, the induction of the host plant’s immune response (Induced Systemic Resistance), and competition for nutrients and space. In addition, parameters governing the selection of effective biocontrol agents and their survival in plant microbial communities are discussed. The influence of the microbiota on the establishment and development of biocontrol agents can assess the potential of these treatments and facilitate the development of effective biopesticides during their field application.

根际芽孢杆菌对植物尖孢镰刀菌的生物防治效果:可持续农业的一条有前途的途径

在植物病害管理策略中，生物防治是替代化学药剂防治尖孢镰刀菌(Fusarium oxysporum)血管性枯萎病的一种可持续的方法。枯萎病是影响多种植物的最具破坏性的疾病。芽孢杆菌是控制这些真菌疾病最广泛使用的生物防治候选者。本文综述了尖孢镰刀菌的致病性、毒力机制以及寄主植物与病原菌的相互作用。芽孢杆菌采取的控制手段可以抑制或杀死这些植物病原体。芽孢杆菌产生多种次生代谢物，包括挥发性和非挥发性有机化合物。生物防治潜力是通过直接的抗菌活性、诱导寄主植物的免疫反应(诱导系统性抗性)以及对养分和空间的竞争来实现的。此外，还讨论了控制有效生物防治剂选择的参数及其在植物微生物群落中的存活。微生物群对生物防治剂的建立和开发的影响可以评估这些处理方法的潜力，并在其现场应用过程中促进有效生物农药的开发。

期刊介绍： Microbiology Research is an international, online-only, open access peer-reviewed journal which publishes original research, review articles, editorials, perspectives, case reports and brief reports to benefit researchers, microbiologists, physicians, veterinarians. Microbiology Research publishes ‘Clinic’ and ‘Research’ papers divided into two different skill and proficiency levels: ‘Junior’ and ‘Professional’. The aim of this four quadrant grid is to encourage younger researchers, physicians and veterinarians to submit their results even if their studies encompass just a limited set of observations or rely on basic statistical approach, yet upholding the customary sound approach of every scientific article.
