Current Project

Title: The role of mycorrhizal fungi in the nutrition of temperate terrestrial orchids

University: School of Plant Biology, University of Western Australia

Collaborators: Dr Hans Lambers, Prof Kingsley Dixon, Dr David Read

Description: The roots of more than 80% of terrestrial plant species associate intimately with fungi to form mycorrhizas. The family Orchidaceae constitutes the largest plant family on earth with over 25, 000 species, the majority of which use mycorrhizal fungi. However, relatively little is known of the functional significance of these mycorrhizal fungi. This project will examine the exchanges of carbon, nitrogen and phosphorus between selected orchids and their symbionts. The reciprocal processes of nutrient capture and transfer from soil to orchid will also be evaluated. This study will provide the first insights into the role of orchid fungi in the capture and transport of nutrients across a range of orchid taxa encompassing the major fungal groups, ecological strategies and colonisation types. This research will contribute to the basic eco-physiological understanding that is required to underpin orchid conservation efforts.
