Genetic Architecture of Symbiosis

Symbiosis is commonly associated with gene loss, but ectomycorrhizal fungi appear to have expanded genomes. The genus Amanita encompasses both asymbiotic and ectomycorrhizal species, and we are currently working with the genomes of six of these species to identify the genetic hallmarks of symbiosis.
