Funded Activity Summary
Carboxylate exudation and phosphorus acquisition in eucalypts. Eucalypts are thought to rely on mycorrhizas to acquire phosphorus (P). Using leaf manganese concentrations in the field to proxy rhizosphere carboxylates, followed by plant growth in low P-solutions, it was shown that some, but not all eucalypts that grow on P-impoverished soils release carboxylates from their roots. This trait is a strategy of Proteaceae to access soil P, but assumed not to be used by eucalypts. This game-changing discovery challenges the current dogma that eucalypts invariably rely on mycorrhizas to acquire P. This project will explore the significance of this newly-described trait for functioning of eucalypts more broadly and produce results that are important for conservation, restoration and forestry activities.Funded Activity Details
