This genome was sequenced as part of the JGI CSP1953 within the framework of the Mycorrhizal Genomes Initiative, which seeks to densely sample members of a diverse lineage of ectomycorrhizal (ECM) fungi to examine functional diversity of ECM fungi with a shared evolutionary history.

Pisolithus marmoratus:

The mutualistic ectomycorrhizal (ECM) fungal genus Pisolithus colonizes the roots of trees in forests around the world and are inoculated on bioenergy crops such as Eucalyptus sp. and Pinus sp. due to their role in promoting plant health and productivity under different environmental constraints. Made up of >16 cryptic species, members of the Pisolithus genus are found in environments that vary broadly with regard to temperature, nutrient levels and heavy metal concentrations. Pisolithus marmoratus has been described in many different situations around the globe in dry, warm environments and colonizing a number of hosts from the Myrtaceae. While the entire Pisolithus genus is typically easy to manipulate in culture, P. marmoratus is typically short lived when it is separated from its host.
