Really Trees Could 'Talk'?

Through a chemical compound, a tree being attacked by pests can warn other trees.

It turned out that not only animals that can communicate with each other. Researchers concluded that the trees were able to establish communication to others.
As reported by the site IO9, Ian Baldwin, director of the Max Planck Institute for Chemical Ecology, published a paper which concluded that the tree can spread a chemical compound to 'communicate' with another tree nearby.
According to Baldwin, when a tree is attacked by the insecticide he researched, the tree will produce tannin and various other chemical compounds.
The compound is usually removed to inhibit the growth and availability of food for the larvae of insecticides that, as well as to defend themselves from further attacks of these insecticides.
Other Baldwin findings, after which it was not just a tree that was attacked insektsida have issued the chemical compound, but also other trees that have not been attacked, issued the same compound.
Baldwin and his colleagues conclude, the chemical was issued as a mechanism to warn of potential dangers faced by other trees that also could prepare a defense.
Further research using molecular and genetic analysis found that chemical compounds are released through the leaves, ranging from simple small molecules such as ethylene, up to more complex compounds such as methyl jasmonate.
These compounds diffuse to the air, and when it touches another tree, the tree responds by making changes in growth and chemical synthesis.
"The chemical communication of plants that we thought was a kind of indirect shouts" Danger! "Or" Beware! ", But not such a dialogue."
While even tree roots will also issue a number of different chemical communication. However, because these compounds are in the soil, he will not be able to spread so far kmia compounds which spread through the air and water.
Now researchers are working to investigate and analyze the chemical compounds for compounds that information can be genetically modified and used for the purposes of eradication of pests for crops to be harvested.
