The Ben-Gurion University team discovers plants can transmit distress signals to each other through their roots.
Israeli scientists have uncovered messages transmitted underground – not by enemy agents, but by garden pea plants.
The Ben-Gurion University team discovered that plants can transmit distress signals to each other through their roots. An injured plant “communicates” to a healthy one, which in turn relays the signal to neighboring plants, possibly enhancing the other plants’ ability to deal with stress in the future, according to the study, recently published in the periodical PLoS (Public Library of Science One ).
The researchers, headed by plant biologist Ariel Novoplansky of the Mitrani Department of Desert Ecology, exposed five garden pea plants to drought conditions.
