Assessment of virome response in birch (Betula sp.) to climate change

树木在不同的生态系统中的下降需要更多的研究，以阐明机制的原因，特别是在植物病原病毒和不断变化的气候条件之间的相互作用的背景下。该项目将获得更多关于落叶树在不断变化的气候条件下，即气温升高和土壤干燥程度降低的情况下，混合病毒感染的影响的信息。根据我们20年的经验，我们得出结论，病毒在城市和森林树木中广泛存在。到目前为止，这些病毒与其他胁迫因子相互作用的程度还没有在树木中研究过。气候变化对受病毒感染的树木的影响特别令人感兴趣，并在研究中提出了挑战。为了更好地了解复杂的病毒/植物相互作用，以及气候变化将如何影响这种相互作用，捕获转录组和蛋白质组（应激）反应是有用的。特别是，在这一设想的综合办法中，将研究气候变化，即空气变暖和干旱胁迫（即土壤缺水）对适应北方温带和寒带气候地区的病毒植物病理系统的影响。通过使用最近发现的桦树病毒组作为模型系统来实现。气候变化条件下天然树木病毒对树木转录组和蛋白质组的影响的研究是新颖的。由于种子种植园是未来城市或森林树木栽培的活胚芽，研究病毒状态和病毒/植物系统与气候变化的相互作用对重新造林至关重要。在这个计划中，我们将连接不同的学术思想流派-植物病毒学和植物生理学。这将加强参与者在植物科学和病毒学领域的学科能力，通过跨学科团队的合作。博士生将学习汇集所涉及学科的方法，并从系统思维和协同效应中受益。

Tree decline in diverse ecosystems calls for more research to elucidate the mechanistic reasons, especially in the context of interactions between phytopathogenic viruses and changing climatic conditions. This project will gain more information about the impact of mixed viral infection in deciduous trees under changing climatic conditions, i.e. increased air temperatures and decreasing soil drying. As a result of our 20-years of experience, we conclude that viruses are widespread in urban and forest trees. How far these viruses do interact with other stress factor is not studied in trees so far. And the impact of climate change in virus infected trees is of particular interest and causes a challenge in research. To get a better understanding about the complex virus/plant interaction, and how this will be affected in the light of changing climate, is it useful to capture transcriptomic and proteomic (stress) responses. In particular, the influence of climate change, i.e. air warming and drought stress (i.e. soil water scarcity), on the virus plant pathosystem, which is adapted to northern areas of temperate and boreal climates, will be studied in this envisaged comprehensive approach. Doing so by using the recently discovered birch virome as a model system. The investigation of the impact of natural tree virome on tree transcriptomes and proteomes under climate change conditions is novel. As seed plantations are living germplasms for future urban or forest cultivation of trees, studying the viral status and the interaction in virus/plant systems to climate change is of essential interest for reforestation. Within this program, we will connect different academic schools of thought - plant virology and plant physiology. This will strengthen the disciplinary competence of the participants in the fields of plant science and virology by working together in a cross-disciplinary team. The PhD students will learn to pool approaches of the involved disciplines and benefit from systems thinking and synergistic effects.
