Volatile-mediated interspecific plant interaction promotes root colonization by beneficial bacteria via induced shifts in root exudation

Potato-onion VOCs-specifically dipropyl disulfide-can induce shifts in the root exudate of adjacent tomato plants, which results in the recruitment of plant-beneficial bacteria in the rhizosphere. Taken together, this study elucidated a new mechanism of interspecific plant interaction mediated by VOCs resulting in alterations in the rhizosphere microbiota with beneficial outcomes for plant performance.
