Codependency between plant and arbuscular mycorrhizal fungal communities: what is the evidence?

What is it about?

The mycorrhizal symbiosis between plants and arbuscular mycorrhizal fungi is important for biodiversity both above and below ground. We do not yet understand, however, how these communities are linked. We know that these communities are nonrandomly associated in most cases, but is it because they are responding to environmental conditions, or are the partners ‘choosing’ each other?
