Integrating plant-to-plant communication and rhizospheremicrobial dynamics: ecological and evolutionary implicationsand a call for experimental rigor

Abstract

The perception of airborne chemical signals by plants can trigger reconfigurations of their metabolism that alter their bioticinteractions. While plant-to-plant chemical communication has primarily been studied in the context of eliciting defenses toherbivores and pathogens, recent work suggests that it can also affect plants’ interactions with their rhizosphere microbiomes. Inthis perspective, we discuss the potential for integrating the fields of plant-to-plant communication and microbial ecology tounderstand the chemical ecology of plant−microbiome interactions. As an introduction for microbial ecologists, we highlightmechanistic knowledge gaps in plant volatile organic compound (VOC) perception and provide recommendations for avoidingcommon experimental errors that have plagued the plant communication field. Lastly, we discuss potential implications of plantVOCs structuring rhizosphere microbiomes, particularly effects on plant community and evolutionary dynamics. As we continue todiscover links between plant metabolism and their microbiomes—from molecular to community scales—we hope that thisperspective will provide both motivation and words of caution for researchers working at the intersection of these two fields
