Amplicon ITS and 16S RNA seq of soil metagenome: Quantifying plant-soil feedback effects in classic diversity-productivity experiments

Two-way interactions between plants and soil microbiota, also known as plant-soil feedbacks, have major effects on the productivity of plant species. This project tested the role of plant-soil feedbacks in plant community productivity across two sites, one at Cedar Creek Ecosystem Science Reserve in East Bethel, Minnesota, USA, and the other at the Jena Experiment in Jena, Thuringia, Germany. Soil metagenomic analyses were undertaken to help identify the specific microbes that drive feedbacks.

植物与土壤微生物群（soil microbiota）之间的双向互作，亦称植物-土壤反馈（plant-soil feedbacks），对植物物种的生产力具有显著影响。本项目选取两处试验站点开展研究，以探明植物-土壤反馈在植物群落生产力中的作用：一处位于美国明尼苏达州东贝瑟尔的塞达克里克生态科学保护区（Cedar Creek Ecosystem Science Reserve），另一处位于德国图林根州耶拿的耶拿试验平台（Jena Experiment）。研究通过土壤宏基因组分析，辅助甄别驱动植物-土壤反馈的特异性微生物类群。
