Abstracts |
The majority of vascular plants are mycorrhizal: 72% are arbuscular mycorrhizal (AM), 2.0% areectomycorrhizal (EcM), 1.5% are ericoid mycorrhizal and 10% are orchid mycorrhizal. Just 8%are completely nonmycorrhizal (NM), whereas 7% have inconsistent NM–AM associations.Most NM and NM–AM plants are nutritional specialists (e.g. carnivores and parasites) or habitatspecialists (e.g. hydrophytes and epiphytes). Mycorrhizal associations are consistent in mostfamilies, but there are exceptions with complex roots (e.g. both EcM and AM). We recognizethree waves of mycorrhizal evolution, starting with AM in early land plants, continuing in theCretaceous with multiple new NM or EcM linages, ericoid and orchid mycorrhizas. The thirdwave, which is recent and ongoing, has resulted in root complexity linked to rapid plantdiversification in biodiversity hotspots. |
