Abstract:
Mycorrhizal fungi, because of their obligate symbiotic interaction with plant roots, may either promote or restrict plant diversity depending on broad or narrow plant-fungus relationships. It was challenging to investigate these relationships in a hotspot of plant diversity, the tropical mountain rain forest of Southern Ecuador. Inventories, based on morphotyping and DNA sequencing, were carried out on the mycorrhizal fungi associated with 115 tree species belonging to 40 families, 20 ericad species and 4 epiphytic orchid species in an area of about 12 ha in the Reserva Biológica San Francisco at 1 850 to 2 300 m. Results indicated that diverse Glomeromycota with broad host range may promote high tree diversity, while diverse but plant-family restricted Sebacinales likely support closely related Andean ericads, and diverse, orchidrestricted Tulasnellales and Sebacinales closely related epiphytic orchids. Ectomycorrhizal fungi were found specifically associated with three Nyctaginacean trees and with one member of Melastomataceae. We conclude that the extraordinary high plant diversity of the tropical Andean forest is predominantly promoted by a broad range of mycorrhizal fungi but selected trees are supported by specific fungi. <br/> <br/>
