How do plant cells communicate

When plants communicate with each other

Plants don't speak like we do, but through chemical substances that they give off through leaves and roots. These messenger substances reach other plants in the vicinity through the air or the soil. Scientists are finding out more and more about how sophisticated and sophisticated this chemical communication is.

Plants warn of tight spaces

The message from maize plants in the current study by the University of Uppsala in Sweden could be in human language: "Pretty close here. Someone nudges me all the time. So neighboring plants, think carefully about where you are growing."

Touch is an important signal for plants

In the study, the researchers simulated touching the leaves of different maize plants and were able to show that the maize plants notice when they are touched. In previous studies it had already been shown with other plants such as tomatoes or herbs that touching them influences the growth of the plants. They change the metabolism.

Seedlings like it undisturbed

With their experiments on maize plants, the researchers have now been able to show that the roots of plants that are often touched also emit chemical signals. These substances are transferred through the soil and through moisture. So the plants not only perceive that they are being touched, they also talk about the roots. And the plants in the area react.
