The silence in the garden can be deceiving. Scientists were finally able to confirm the long-standing assumption of many gardeners that plants are able to exchange information.
Researchers have found out in the course of the experiment, the plants can talk to each other, modifying the gene representative of the cabbage family, who initiated the production of gas when the surface of the plant was damaged - incised or punctured. By adding a DNA plant thermosensitive luciferase protein which causes glow of fireflies in the dark, scientists using cameras could observe plant emissions.
Scissors cutting off a leaf of cabbage at the plant, the researchers noticed that it began to emit gas methyl jasmonate, telling it to their neighbors about the possible danger. Two other intact plants that were next, receiving a warning, began to prepare for "defense." Plant leaves have started to actively produce toxic chemical substances intended to reflect these potential predators such as caterpillars.
This process was first captured on camera and, as they note, confirms the likelihood that plants communicate with each other on the complex "invisible" to our language, about which we know nothing.
The footage will be presented in the "How to grow a plant" (How to Grow a Planet) on the channel BBC2 on Tuesday, Professor Ian Stewart (Iain Stewart). Watching the experiment at the University of Exter (Exeter), Professor Stewart said the following: "It was obvious that the gas released by the damaged plant, initiated changes in the biological activity of two of his brothers are nearby. Recent recognize a message warning them of the danger and calling for self-defense .’s amazing to think that in the silence of the garden plants are actually constantly talking to each other, but we are not able to hear it. Most people believe that the plants are fairly passive way of life, but in reality they move, feel and communicate with each other. Together These abilities can be compared with the intelligence of plants. "
Research work was carried out by Professor Nick Smirnov (Nick Smirnoff), who noted that this does not mean that plants can feel pain because they do not have nerves. Professor of Biochemistry Smirnov, added: "We have been able to show clearly that the plants begin to allocate a certain gas when they are injured, so as to warn their neighbors of the danger. But we still do not know why this is happening. Perhaps it was an attempt to plant to warn against the danger of his other undamaged parts, and neighboring plants just happened to react to the signal. Alternatively, the plants for some reason specially developed this ability. But then it is not clear why, because it is assumed that in nature plants must compete with each the other, fighting for survival. Thus, we still have a lot of work to figure out the real cause of the mysterious phenomena of plant life. "
