<b>Arbuscular mycorrhizal fungi enhance nitrogen acquisition from, but not carbon loss of, organic matter in soil</b>

This dataset includes an experimental dataset and a meta-analysis dataset for investigating the effect of arbuscular mycorrhizal fungi (AMF) in mediating the relationship between plant N acquisition from, and decomposition of organic substrates. The experimental data are results from an experiment using mycorrhizal-defective mutants and wild-types of two plant species with isotopically labelled litter to trace the allocation of carbon and nitrogen drived from litter in plant and soil. The meta-analysis dataset collected 108 entries from 43 studies that also employed stable isotopically labelled organic substrates. The meta-analysis dataset also includes information on the properties of the added organic substrates (type and ln-transformed C:N ratio) and the experimental design (methods used for AMF exclusion and spatial distribution of organic substrates).本数据集包含用于探究丛枝菌根真菌（arbuscular mycorrhizal fungi，AMF）介导植物从有机底物获取氮与有机底物分解之间关系的实验数据集与荟萃分析数据集。实验数据源自一项以菌根缺陷突变体与两种植物的野生型为受试材料、使用同位素标记枯落物示踪枯落物衍生碳与氮在植物及土壤中分配规律的试验结果。荟萃分析数据集整合了来自43项研究的108条记录，这些研究均采用了稳定同位素标记的有机底物。此外，该荟萃分析数据集还涵盖了所添加有机底物的相关属性（底物类型与经自然对数转换的碳氮比）以及试验设计相关信息（AMF排除方法与有机底物的空间分布方式）
