Wild relatives of rice are found across northern Australia. The project aims to apply emerging technologies for efficient whole genome sequencing to determination of the genetic diversity of these populations in relation to cultivated rice and wild rice from other parts of the world. The role of the Australian populations in the evolution of rice and the potential of these populations to contribute valuable diversity to rice crops worldwide are intended to be analysed. The impact of domestication on rice in Asia is expected to be established by the characterisation of the related Australian populations that were isolated from the impacts of agriculture for around 7000 years. Whole genome associations with environment may provide clues to adapting agriculture to climate.

野生水稻的近亲遍布澳大利亚北部。该项目旨在应用高效全基因组测序的新兴技术来确定这些群体与来自世界其他地区的栽培水稻和野生水稻的遗传多样性。旨在分析澳大利亚种群在水稻进化中的作用，以及这些种群对世界各地水稻作物作出宝贵多样性的潜力。驯化对亚洲水稻的影响预计将通过描述相关的澳大利亚种群的特征来确定，这些种群与农业的影响隔离了大约7000年。全基因组与环境的关联可能为农业适应气候提供线索。
