Plants integrate responses between two spatially separated habitats: air and soil, with different communities of heterotrophs depending on the same host. Little is known about the chemical mediators of interactions between aboveground herbivores and root colonizers. Using metabo-lomics and transcriptomics, we will characterize spatiotemporal changes in roots of herbivore-damaged plants and identify underlying signalling pathways. We will genetically modify identified traits to determine their ecological function in interactions with soil bacteria and mycorrhizal fungi and the consequences for herbivore resistance and plant fitness in field experiments.

植物整合两个空间分离的栖息地之间的反应：空气和土壤，不同的异养生物群落依赖于同一主机。很少有人知道的化学介质之间的相互作用地上食草动物和根殖民者。利用代谢组学和转录组学，我们将表征草食动物破坏的植物根的时空变化，并确定潜在的信号通路。我们将对已鉴定的性状进行遗传修饰，以确定它们在与土壤细菌和菌根真菌相互作用中的生态功能，以及在田间实验中对草食动物抗性和植物适应性的影响。
