Within the framework of the JGI Mycorrhizal Genomics Initiative (MGI) project, we are sequencing a phylogenetically and ecologically diverse suite of mycorrhizal fungi (Basidiomycota and Ascomycota), which include the major clades of symbiotic species associating with trees and woody shrubs. Analyses of these genomes will provide new insights into the diversity of mechanisms for the mycorrhizal symbioses, including ericoid-, orchidoid- and ectomycorrhizal associations. A large collaborative effort led by PI of these project, Francis Martin (INRA), aims for master publication(s) of the MGI data analyses. Researchers who wish to publish analyses using data from unpublished MGI genomes are respectfully required to contact the PIs and JGI to avoid potential conflicts on data use and coordinate other publications with the MGI master paper(s).
