DescriptionArmillaria root disease causes extensive damage to tree roots throughout the world, but efficacious management practices are lacking. However, soil interactions among Armillaria species, microbial communities, and trees may determine the impact of pathogenic Armillaria on the growth and survival of trees. Two species, A. solidipes (highly virulent) and A. altimontana (less virulent), frequently co-occur in forests of inland northwestern USA. Soil metagenomics and metatransciptomics may provide key insights into how interactions among soil microbial communities and root pathogens influence disease severity. If we can understand how soil microbial communities influence Armillaria root disease, then we can potentially develop novel management techniques that enhance biocontrol microbes and favor microbial communities that suppress disease caused by virulent Armillaria species.
