Healthy plants, like all higher organisms, host an extensive microbiome which contain both beneficial and pathogenic species. A major driver of microbiome assembly is by the release of exudates from the plant which can attract microbes into the roots from the surrounding soil, which can then travel to other areas of the plant. These microbes play important roles in plant health including disease protection, plant growth, and overall plant functioning through factors such as improving nutrient availability and resilience to abiotic stress. This project will focus on characterising the relationship between the plant and phyllosphere microbiome through time, as well as the relationship between the various microbial species that make up this complex environment. The project will fully characterise these dynamics via a metabarcoding approach to analyse the impact of time of day on the community structure and composition. Understanding the dynamic nature of the plant-microbe interactions will be important for our understanding and monitoring of ecosystem health in the context of climate change and the effects of pollution or in the oversight of ecosystem recovery following anthropogenic disruption. The knowledge will also be important for the development of new integrated pest management strategies in support of sustainable agriculture.

像所有高等生物一样，健康的植物具有广泛的微生物组，既有有益和致病性物种。微生物组组件的主要驱动因素是从植物中释放出渗出液，该植物可以将微生物吸引到周围土壤中的根中，然后可以进入植物的其他区域。这些微生物在植物健康中起着重要作用，包括疾病保护，植物生长以及通过改善营养可用性和对非生物压力的弹性等因素的整体植物功能。该项目将着重于表征植物和植物圈微生物组之间的关系，以及构成这种复杂环境的各种微生物物种之间的关系。该项目将通过元编码方法来完全表征这些动态，以分析一天中的时间对社区结构和组成的影响。了解在气候变化以及污染的影响或在人为破坏后对生态系统恢复的监督下，了解和监测生态系统健康的理解和监测对我们对生态系统健康的理解和监测至关重要。该知识对于发展新的综合有害生物管理策略以支持可持续农业也将很重要。
