Welcome to PisolithusDB, the Pisolithus microcarpus database
Within the framework of the JGI Mycorrhizal Genomics Initiative, we are sequencing a phylogenetically and ecologically diverse suite of mycorrhizal fungi (Basidiomycota and Ascomycotina), which include the major clades of symbiotic species associating with trees and woody shrubs. Analyses of these genomes will provide insight into the diversity of mechanisms for the mycorrhizal symbiosis, including endo- and ectomycorrhiza.
The fungal genus Pisolithus is cosmopolitan in warm temperate regions of the world and forms ectomycorrhizal associations with a wide range of woody plants including members of the Pinaceae, Myrtaceae, Fagaceae, Mimosaceae, Dipterocarpaceae and Cistaceae. P. tinctorius and P. microcarpus species are typically one of the most frequent fungi to colonize pines and eucalypts, respectively, in primary successional settings in their native habitat. They are currently used in the commercial forestry industry to inoculate conifer or eucalypt seedlings for lumber and landscape trees. To elucidate the genetic basis of this ecologically important behavior, sequencing of P. tinctorius and P. microcarpus is on-going at the Joint Genome Institute.
