Plants warn one another of threats


Believe it or not, plants talk to each other. A new study by an international team has found that the communication skills of plants are much more advanced than previously thought. In fact, they can warn their neighbours of potential threats. Chemical messages exchanged between plants allow them to send out alerts when pests attack and even discuss the presence of pollinators such as bees. Lead researcher Richard Karban of the University of California said that the study showed that plants are capable of more sophisticated behavior than we imagined. He also said, plants not only respond to reliable cues in their environments but also produce cues that communicate with other plants and with other organisms.
