Most of our timber producing trees are depending on a root associated symbiosis with fungi called ectomycorrhiza (ECM). ECM communities usually containing only a few stand forming trees but hundreds of fungal species from many disparate lineages. ECM Fungi are also globally diverse with >7700 spp. in >78 separate clades.This project will set up an infrastructure to address ecological and evolutionary questions in the kingdom Fungi and apply it to six interrelated questions about: 1. the evolution of ECM, 2. the evolution of ECM plant partner association and other ecological traits, 3. the frequency of long distance dispersals, 4. the processes of species diversification, 5. ECM Fungi community structure at different scales, 6. Genome evolution in ECM lineages.The infrastructure will consist of a database with sequence, ecological, and geographic data that will be linked to a robust and inclusive phylogeny. The ecological and geographic data will expand on the existing database PlutoF while the phylogeny will be based on two datasets. 1. Genomic data from public databases and newly generated next generation sequencing data will be used to resolve deep nodes in the tree. 2. GenBank data and newly generated Sanger sequences will be used to populate the clades with a dense taxon sampling.The genomic data will also be used to answe questions on genome evolution. All questions will be addressed using mainly model based methods.
