Approximately 41% of the 5750 plant species in Western Australia are susceptible to Phytophthora cinnamomi a pathogen recognised as a key threatening process to Australia's biodiversity by the Federal Government. This project will enhance our understanding of how the pathogen survives in soil and tolerant plant species. It will determine how the pathogen is able to survive long-term as dormant propagules and how this dormancy can be broken. This project will be relevant to managers of natural ecosystems and to the horticultural industries throughout Australia and will assist in developing effective ways to manage this ecologically devastating plant pathogen.

在西澳大利亚州5750种植物中，约有41%对肉桂疫霉敏感，这种病原体被联邦政府确认为威胁澳大利亚生物多样性的关键过程。这个项目将加强我们对病原体如何在土壤和耐受植物物种中生存的了解。它将决定病原体如何能够作为休眠繁殖体长期存活，以及如何打破这种休眠。该项目将与自然生态系统的管理者和整个澳大利亚的园艺产业相关，并将有助于开发有效的方法来管理这种具有生态破坏性的植物病原体。
