Root Exudates Regulate Soil Fungal Community Composition and Diversity

Friday, December 16, 2016

Nonresident plants and root exudates influenced the fungal community by both positively and negatively
impacting the relative abundance of individual phylotypes. A net increase in fungal biomass was observed when nonresident root exudates were added to resident plant treatments, suggesting that increases in specific carbon substrates and/or signaling compounds support an increased soil fungal population load. This study establishes root exudates as a mechanism through which a plant is able to regulate soil fungal community composition.
