Plant social networking system.

The plant social networking system (SNS) is conceptualized as a four-phase, cue-mediated transfer from a donor holobiome to a receiver holobiome.

• Why it matters: Existing frameworks for plant-plant interactions are fragmented and do not integrate how cue transfer and microbiome reconfiguration work together across holobiomes.
• What they did: The opinion article proposes a four-phase model linking external stimuli, donor root microbiome reorganization, cue production/transmission, receiver cue perception, and microbe recruitment.
• The result: The plant SNS framework extends classical interaction concepts and offers a basis for explaining plant interactions as integrated holobiome-level processes.
