项目摘要
Bacterial communities associated to above-ground plant parts are crucial for plant health. The composition of these is considered to be determined by their original sources such as soil but also by plant traits as the availability of carbon and nitrogen or the composition of secondary metabolites. Although flowers are directly linked to plant fitness and reproduction, bacterial colonizers of the anthosphere are less well characterized and their ecological roles are less well understood compared to bacteria associated with leaves. Additionally, the determinants of their diversity as well as their responses to environmental gradients such as variation in land-use intensity are unknown. By using the hierarchical organization of the biodiversity exploratories, we are planning to investigate the organismal and genetic alpha-, beta- and gamma- diversity of floral microbiomes as a function of land-use, plant diversity, and functional flower traits such as floral scents and the availability of carbon and nitrogen in order to understand links between these different levels of biodiversity. These data will allow us to gauge the relative importance of environmental and plant-based factors. Thus, our results will provide a novel perspective on associations between bacteria and flowers and help to understand effects of anthropogenic alterations of the environment on organismal and genetic diversity.
与植物地上部分相关的细菌群落对植物健康至关重要。它们的组成被认为是由它们的原始来源,如土壤,但也由植物特性,如碳和氮的有效性或次生代谢物的组成决定的。虽然花与植物的适合性和繁殖直接相关,但与与叶子相关的细菌相比,花冠圈的细菌定殖者的特征较差,其生态作用也不太清楚。此外,它们多样性的决定因素以及它们对环境梯度的反应,如土地利用强度的变化,都是未知的。通过生物多样性探索的层级组织,我们计划调查植物微生物群落的生物和遗传α、β和伽马多样性,作为土地利用、植物多样性和花卉功能特征(如花香和碳和氮的有效性)的函数,以了解这些不同水平的生物多样性之间的联系。这些数据将使我们能够衡量环境因素和植物因素的相对重要性。因此,我们的结果将为细菌和花卉之间的联系提供一个新的视角,并有助于理解人为环境变化对生物和遗传多样性的影响。
