The phosphorus (P)-impoverished nature of the soils of south-western Australia has allowed the evolution of many plant species that are amazingly efficient at acquiring and utilising P. Among the most P efficient are species of the Proteaceae, which produce cluster roots. We will explore why less efficient species can co-occur with the very efficient Proteaceae. A deep and thorough understanding of the mechanism determining P efficiency of these species will contribute significantly to our basic understanding of P nutrition in plants and to our understanding of the P-impoverished ecosystems of the southwest. It will also assist in developing crops that are more efficient at acquiring and/or utilising P.

澳大利亚西南部土壤的磷（P）贫乏性质允许许多植物物种的进化，这些植物在获得和利用P方面非常有效。我们将探讨为什么效率较低的物种可以与非常有效的Proteaceae共存。深入了解这些物种的磷效率决定机制，将有助于我们对植物磷营养的基本认识和我们对西南地区磷贫生态系统的理解。它还将有助于开发更有效地获取和/或利用磷的作物。
