Plants warn their relatives about the danger

Plants have many special qualities thatdistinguish them from other inhabitants of the planet. So, plants do not get cancer, they are able to adapt to the natural needs of other living organisms and even know how to transmit information in the event of an imminent danger. Scientists from Cornell University have proven that plants can communicate with each other when they are attacked by pests.

Plants are able to warn each other about the threat of pests

Can plants communicate with each other?

New study by scientists from CornellUniversity has shown that plants are able to exchange messages in the form of airborne chemicals, which are known as volatile organic compounds. Thanks to these substances, plants have a specific open communication channel through which information on the approach of pests is transmitted.

In order to confirm or denyThis theory, Andre Kessler, professor of ecology and evolutionary biology at Cornell, conducted an interesting observation of a plant of the species Solidago altissima and leaf beetle. According to his research, the smells of attacked plants become similar to each other. In other words, plants are able to communicate in the same language of smells, allowing them to freely share information on one another or another.

Volatile organic compounds help plants communicate with each other

A study by Andre Kessler found thatnearby plants pick up warning signals and prepare for the potential threat that a pest may become. According to Kessler, plants change their metabolism at the time of the attack, which helps them cope with the attackers. A person has a similar survival strategy, which is a well-known immune system. Despite the fact that plants do not have antibodies, these living organisms can fight insects attacking them in their own way with the help of special protective compounds that kill herbivores and thus save the plant from death.

Researchers believe that conclusions based onmonitoring can bring some benefits to farmers and those involved in agriculture. Thus, the results of the study have already been successfully applied in Kenya, where a new system for the protection of cultivated plants from pests, based on the principles of interaction of various plant species and their communication, is already being commissioned.
