Funded Activity Summary
Carboxylate exudation and phosphate nutrition in Hakea prostrata (Proteaecea). Nonmycorrhizal Proteaceae are very successful in acquiring phosphate from nutrient-impoverished soils; their cluster roots account for this. They are also extremely sensitive to phosphate toxicity. We will elucidate aspects of production and release of carboxylates that are associated with functioning of cluster roots, using Hakea prostrata (Proteaceae) as a model. Types and rates of exudation by cluster roots, as influenced by development and environmental signals, will be assessed. Our findings will provide key information on adaptive mechanisms associated with both phosphate acquisition from phosphate-fixing soils and phosphate toxicity.Funded Activity Details
