This project will specifically test alternative hypotheses about how weeds become invasive. As invasive weeds affect both agricultural and native ecosystems equally, research on understanding the mechanisms of weed invasion is critical. Outcomes will benefit Australia by allowing better prioritisation of management against exotic plants already in the country by providing predictive tools to estimate likelihood of spread. For formal Pest Risk Analysis by regulators (eg Biosecurity Australia), our project will provide genomic tools by which the potential weediness of a regulated plant can be assessed through genetic screening, and forms part of an international effort to identify 'weedy genes'.

这个项目将专门测试关于杂草如何成为入侵的替代假设。 由于入侵杂草对农业和本地生态系统的影响是一样的，因此了解杂草入侵机制的研究至关重要。 结果将有利于澳大利亚，通过提供预测工具来估计传播的可能性，从而更好地优先考虑对已经在该国的外来植物的管理。 对于监管机构（如澳大利亚生物安全局）的正式有害生物风险分析，我们的项目将提供基因组工具，通过基因筛选可以评估受管制植物的潜在杂草性，并形成国际努力的一部分，以确定“杂草基因”。
