Ectomycorrhizal communities in Fagus sylvatica forests

We addressed the legacies of past land use and the recovery of the mutualism between ECM fungi and Fagus sylvatica trees in regenerating recent beech forests (< 50 years) in Northeast Spain. Root and soil samples were collected in 6 long-established and 8 recent beech forests to analyze soil abiotic properties (pH, organic matter, soil moisture, soil texture, P and N) and the ECM fungi associated to beech roots (Illumina DNA metabarcoding of ECM tips).

本研究针对西班牙东北部林龄小于50年的再生山毛榉林，探讨了过往土地利用的遗留效应，以及外生菌根（Ectomycorrhizal, ECM）真菌与欧洲山毛榉（Fagus sylvatica）之间互利共生关系的恢复过程。研究团队在6处成熟山毛榉林与8处近年山毛榉林中采集根系与土壤样本，用于分析土壤非生物属性（pH值、有机质含量、土壤含水量、土壤质地、磷与氮含量），并通过对外生菌根根尖的Illumina DNA元条形码测序，解析与山毛榉根系关联的外生菌根真菌群落。
