This research will significantly advance knowledge regarding the evolution of mutualisms between plant and soil microbes. Results will provide valuable data on the importance of below-ground microbial community structure to growth and productivity of an ecologically important component of the Australian flora (Acacia spp.), and contribute to the development of best ecosystem restoration practices. Furthermore, it will see the continued development of the Acacia-rhizobia system as a world-class model for exploring interactions between perennial legumes and microbial symbionts. The research also investigates the adaptability and potential for rapid evolution of critical elements of the soil microflora to environmental change.

这项研究将极大地促进对植物和土壤微生物之间相互作用的进化的认识。研究结果将提供有价值的数据，说明地下微生物群落结构对澳大利亚植物区系(Acacia spp.)的一个生态重要组成部分的生长和生产力的重要性，并有助于制定最佳生态系统恢复做法。此外，它还将继续发展相思-根瘤菌系统，作为探索多年生豆科植物与微生物共生体之间相互作用的世界级模式。这项研究还调查了土壤微生物区系的关键元素对环境变化的适应性和快速进化的潜力。
