Background and ScopeGrowing evidence suggests that volatile organic compounds (VOCs) play important roles in plant-plant, plant-microbe and plant-environment interactions. Demonstrating such mechanisms requires the use of innovative analytical techniques to monitor VOCs in and above soils. In this issue, Waters et al. provide experimental evidence that stolons of the woodland strawberry, Fragaria vesca, forage for nutrient-rich soil patches by a chemotropic mechanism.
