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形式之一。然而，当前关于菌根共生的结构与功能的大规模通用规律仍较为匮乏，因为该共生关系的性质可从互利共生演变为寄生，且整体呈现较强的情境依赖性。我们在此公布MycoDB数据库的公开版本：该数据库整合了来自438篇独立发表的文献的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演化情境。本团队历经十余年，联合近80名合作者，收集了植物生物量对菌根真菌接种的响应数据，其中包含元分析统计指标，以及描述每项研究生物与非生物情境的24项额外解释变量。本数据库还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。我们希望通过共享这些数据，凸显菌根研究领域现存的显著空白，并推动综合研究，以探索支配生态系统中菌根功能的通用生态与演化规律。
