商业接种剂的干预有可能减少农业的环境足迹，但它们的不分青红皂白的部署引起了人们对微生物入侵的意外后果的质疑。在没有明确的经验报告，丛枝菌根真菌（AMF）的入侵，我们研究了目前的框架，用于定义AMF入侵，并提供观点的步骤，以避免AMF入侵的负面影响。虽然商业AMF分离物是潜在的入侵者，但入侵并不总是对本地社区的多样性和功能构成负面影响。相反，入侵和居民社区的命运是由选择，漂移，扩散和物种形成等生态过程决定的。尽管如此，我们建议的战略，减少过度依赖引进接种，如采用管理的做法，促进土著AMF社区的多样性和丰富性，并在适用的地区发展本地繁殖作为商业AMF的补充。必须制定从生产到应用全程监控孕育剂价值链的政策和法规，以检查孕育剂的质量和成分，以及在地理位置遥远的地区之间运输孕育剂。
Interventions with commercial inoculants have the potential to reduce the environmental footprint of agriculture, but their indiscriminate deployment has raised questions on the unintended consequences of microbial invasion. In the absence of explicit empirical reports on arbuscular mycorrhizal fungi (AMF) invasion, we examine the present framework used to define AMF invasion and offer perspectives on the steps needed to avoid the negative impacts of AMF invasion. Although commercial AMF isolates are potential invaders, invasions do not always constitute negative impacts on native community diversity and functions. Instead, the fates of the invading and resident communities are determined by ecological processes such as selection, drift, dispersal, and speciation. Nevertheless, we recommend strategies that reduce overdependence on introduced inoculants, such as adoption management practices that promote the diversity and richness of indigenous AMF communities, and the development of native propagules as a supplement to commercial AMF in applicable areas. Policies and regulations that monitor inoculant value chains from production to application must be put in place to check inoculant quality and composition, as well as the transport of inoculants between geographically distant regions.
