Schematic representation of the belowground segregation experiment. Tomato and potatoonion plants were grown in the same box but separated by either a solid barrier (Mono, monoculture with no belowground plant interspecific interaction), a 30-μm mesh barrier (REE, no physical interaction but allowing for root exudate exchange), or no barrier (Inter, allowing for both physical and chemical root interactions).
