Plant below-ground fungi interactions database for 42 Mediterranean woody plant species across Europe and North Africa

[Description of methods used for collection/generation of data] In order to characterize the assemblage of plant below-ground associated fungi in 42 Mediterranean woody species, we collate our own data, from molecular identification of AM (see Garrido et al. 2023 for a complete description of the methods) and EcM fungi (see Prieto et al. 2022 for a complete description of the methods), with bibliographic information containing molecular data for root-associated fungi, for the studied plant species, from MaarjAM database for AM (Opik et al. 2010) and from bibliographic review for EcM fungi. The bibliographic review for EcM molecular data was performed with the following terms: "Genus_species" AND "Ectomyco*" OR "EcM" AND "OTU" OR "VT".
