Arbuscular mycorrhizal symbioses are mutualistic interactions between fungi and most plants. There is considerable interest in this symbiosis because of the strong nutritional benefits conferred to plants and its influence on plant diversity. Until recently, the symbiosis was assumed to be unspecific. However, two studies have now revealed that although it can be largely unspecific with the fungal community composition changing seasonally, in certain ecosystems it can also be highly specific and might potentially allow plants to cheat the arbuscular mycorrhizal network that connects plants below ground.
丛枝菌根共生是真菌与大多数植物之间的互利共生关系。由于这种共生关系能为植物带来显著的营养益处及其对植物多样性的影响，因此备受关注。直到最近，人们还认为这种共生关系是不具特异性的。然而，现在有两项研究表明，尽管在真菌群落组成随季节变化时，它在很大程度上可能不具特异性，但在某些生态系统中，它也可能具有高度特异性，并且植物有可能借此欺骗连接地下植物的丛枝菌根网络。
