Preference, specificity and cheating in the arbuscular mycorrhizal symbiosis.
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.
