The composition, structure, and persistence of plant communities are governed by the extent to which the physical limitation of the environment and biotic interactions promote or hinder individual plant growth performance and reproduction. One especially important biotic interaction is the symbiosis that forms between plants and soil mycorrhizal fungi. The ability of such mutualistic relationships to influence the performance of exotic invasive plants in their introduced range has received increasing attention. Although research is still in progress to determine in more detail how mycorrhizal association directly benefits these two partners (i.e. the invader and its mutualists), it is clear from the current literature that the invaders are capable, through a positive feedback loop, to take advantage from the presence and abundance of mycorrhizal propagules or to transform fungal community in such a way to favor themselves in the expense of native species. Contrastingly, though negative feedback responses are less common in the invader-mycorrhizal fungal association, such responses may lead to depressive effects on the exotic invader. This chapter is dedicated to present and discuss some of the relevant research work that has investigated the possible role that mycorrhizal symbioses play in directing the trajectory of exotic plant invasions.
