Understanding the Hidden Language of Plants

Communicating is key to how plants respond to stress and survive. Unlike animals, plants are sessile, meaning they can’t move around. Unable to run away from danger or relocate when things get stressful, plants have had to develop other ways to cope with challenges in their environment. 

Plants navigate two distinct environments simultaneously: their roots anchor them in soil, while their shoots interact with the air. To thrive in both spaces, plants rely on intricate internal communication systems that transmit information from root to shoot and back again. These interactions occur across multiple scales, from cell-to-cell, root to shoot, in complex exchanges between plants and their environment. Until now, scientists have only been able to capture static glimpses of these conversations.

CROPPS scientists investigate how plants communicate with each other and their environment. By unlocking this biological language, we’re creating new ways for plants, people, and ecosystems to interact.

Research Goals: 

  • Identify the foundational principles of how plants communicate with themselves and with their environment.
  • Understand how plants use macromolecules such as small peptides to understand and respond to their environments
  • Explore how systemic acquired acclimation (SAA), such as reactive oxygen species (ROS), calcium waves, electrical signals, and hydraulic waves are used to rapidly communicate plant stress.  
  • Use synthetic biology tools to uncover and enhance plant communication systems.
