Data from: MycoDB, a global database of plant response to mycorrhizal fungi

Plants form belowground associations with mycorrhizal fungi in one of the most common symbioses on Earth. However, few large-scale generalizations exist for the structure and function of mycorrhizal symbioses, as the nature of this relationship varies from mutualistic to parasitic and is largely context-dependent. We announce the public release of MycoDB, a database of 4,010 studies (from 438 unique publications) to aid in multi-factor meta-analyses elucidating the ecological and evolutionary context in which mycorrhizal fungi alter plant productivity. Over 10 years with nearly 80 collaborators, we compiled data on the response of plant biomass to mycorrhizal fungal inoculation, including meta-analysis metrics and 24 additional explanatory variables that describe the biotic and abiotic context of each study. We also include phylogenetic trees for all plants and fungi in the database. To our knowledge, MycoDB is the largest ecological meta-analysis database. We aim to share these data to highlight significant gaps in mycorrhizal research and encourage synthesis to explore the ecological and evolutionary generalities that govern mycorrhizal functioning in ecosystems.

植物与菌根真菌（mycorrhizal fungi）形成地下共生关系，这是地球上最普遍的共生方式之一。然而，目前关于菌根共生的结构与功能，鲜有普适性的大规模结论，因为这类共生关系的性质从互利共生到寄生不等，且在很大程度上依赖于具体情境。本研究正式发布MycoDB数据库：该库收录了来自438篇独立文献的4010项研究数据，旨在助力多因素元分析（meta-analysis），以阐明菌根真菌调控植物生产力的生态与进化情境。本研究联合近80位合作者，耗时十余年汇编了植物生物量对菌根真菌接种的响应数据，涵盖元分析指标以及24项额外解释变量，用于描述每项研究的生物与非生物情境。本数据库同时收录了库中所有植物与真菌的系统发育树（phylogenetic trees）。据我们所知，MycoDB是目前规模最大的生态元分析数据库。本团队希望通过共享该数据集，揭示菌根研究领域的显著空白，并推动综合研究以探索调控生态系统中菌根功能的生态与进化普适规律。
