Virtually all examined plant species harbour fungal endophytes which asymptomatically infect or colonize living plant tissues, including leaves, branches, stems and roots. Endophyte-host interactions are complex and span the mutualist-pathogen continuum. Notably, mutualist endophytes can confer increased fitness to their host plants compared with uncolonized plants, which has attracted interest in their potential application in integrated plant health management strategies. In this review, we report on the many benefits that fungal endophytes provide to agricultural plants against common non-insect pests such as fungi, bacteria, nematodes, viruses, and mites. We report endophytic modes of action against the aforementioned pests and describe why this broad group of fungi is vitally important to current and future agricultural practices. We also list an extensive number of plant-friendly endophytes and detail where they are most commonly found or applied in different studies. This review acts as a general resource for understanding endophytes as they relate to potential large-scale agricultural applications.
几乎所有被检测的植物物种都含有真菌内生菌，这些内生菌会无症状地感染或定殖于活的植物组织，包括叶片、枝条、茎和根。内生菌与宿主的相互作用很复杂，涵盖了共生体 - 病原体的连续统。值得注意的是，与未被定殖的植物相比，共生内生菌可以提高其宿主植物的适应性，这引发了人们对其在植物综合健康管理策略中潜在应用的兴趣。在本综述中，我们报告了真菌内生菌为农业植物抵御常见的非昆虫害虫（如真菌、细菌、线虫、病毒和螨虫）所带来的诸多益处。我们报告了内生菌针对上述害虫的作用方式，并描述了为何这一广泛的真菌群体对当前和未来的农业实践至关重要。我们还列出了大量对植物有益的内生菌，并详细说明了它们在不同研究中最常见的发现地点或应用情况。本综述作为一种通用资源，有助于理解内生菌与潜在大规模农业应用之间的关系。
