虽然菌根定殖提供了对广泛的土传病原体，包括植物寄生线虫的生物保护作用，丛枝菌根真菌（AMF）作为生物防治剂的商业用途仍处于起步阶段。其中一个主要原因是对作用方式的认识不足。大多数AMF作用模式研究集中在AMF-细菌/真菌病原体。到目前为止，只有少数研究探讨了AMF-植物寄生线虫的相互作用。因此，本研究的目的是确定AMF球囊霉根内是否能够激发香蕉植物对Radopholus similis和Pratylenchus coffeae的系统抗性，这两种植物寄生线虫使用分根隔室设置。AMF减少两种线虫超过50%，即使当AMF和植物寄生线虫在空间上分开。首次证明了AMF具有诱导植物根系对寄生线虫产生系统抗性的能力。
Although mycorrhizal colonization provides a bioprotectional effect against a broad range of soil-borne pathogens, including plant parasitic nematodes, the commercial use of arbuscular mycorrhizal fungi (AMF) as biocontrol agents is still in its infancy. One of the main reasons is the poor understanding of the modes of action. Most AMF mode of action studies focused on AMF-bacterial/fungal pathogens. Only few studies so far examined AMF-plant parasitic nematode interactions. Therefore, the aim of the study was to determine whether the AMF Glomus intraradices was able to incite systemic resistance in banana plants towards Radopholus similis and Pratylenchus coffeae, two plant parasitic nematodes using a split-root compartmental set-up. The AMF reduced both nematode species by more than 50%, even when the AMF and the plant parasitic nematodes were spatially separated. The results obtained demonstrate for the first time that AMF have the ability to induce systemic resistance against plant parasitic nematodes in a root system.
