许多研究表明，与菌根真菌的关联可以改变植物与其敌人之间相互作用的结果。虽然这些影响的方向各不相同，它们的强度表明，需要更多地关注植物天敌，植物和菌根真菌之间的多物种相互作用。我们认识到，菌根真菌可以通过改善植物营养，改变植物耐受性或改变植物防御来影响植物天敌。此外，菌根真菌还可以通过占据根系空间直接干扰病原菌的侵染、植食或寄生。我们正式这些替代结果的多物种的相互作用，并探讨长期动态的植物-敌人的相互作用，这些不同的情况下，使用植物和植物敌人之间的相互作用的一般模型的基础上。然后，我们回顾了文献中的替代机制的假设和这些模型的预测。通过这一努力，我们确定了新的方向，在研究的三营养之间的相互作用的敌人，植物和土壤互利。
A number of studies have shown that an association with mycorrhizal fungi can alter the outcome of interactions between plants and their enemies. While the directions of these effects vary, their strength suggests the need for greater attention to multispecies interactions among plant enemies, plants, and mycorrhizal fungi. We recognize that mycorrhizal fungi could effect plant enemies by improving plant nutrition, modifying plant tolerance, or modifying plant defenses. In addition, mycorrhizal fungi could directly interfere with pathogen infection, herbivory, or parasitism by occupying root space. We formalize these alternative outcomes of multispecies interactions and explore the long-term dynamics of the plant-enemy interactions based on these different scenarios using a general model of interactions between plants and plant enemies. We then review the literature in terms of the assumptions of the alternative mechanisms and the predictions of these models. Through this effort, we identify new directions in the study of tritrophic interactions between enemies, plants, and soil mutualists.
