Genetic variation in pines influencing ectomycorrhizal symbiosis: Potential implications for genotype selection and soil carbon sequestration

Ectomycorrhizal (ECM) fungi provide one of the main pathways for carbon (C) from pines into soils, where these fungi make significant contributions to microbial biomass and soil respiration. However, ECM fungal species vary significantly in traits that likely influence C sequestration, such that forest C sequestration potential may be driven in part by the community composition of ECM fungi. In three recent experiments we found evidence for genetic variation in Pinus species controlling ECM fungal community composition, suggesting the potential to influence ECM community composition through pine genotype selection.
