Plant Communication

http://www.medicaldaily.com/news/20120611/10247/plants-communication-survival.htm

"I was working one day in my herb garden and started to wonder if maybe plants were also sensitive to sounds - why not? - so I decided as a scientist to find out."


While it has been long known that plants grow towards light, previous research from Exeter University found cabbage plants emitted methyl jasmonate gas when their surfaces are cut or pierced to warn its neighbors of danger such as caterpillars or garden shears.

Researchers from the earlier study also found that the when the volatile gas was emitted, the nearly cabbage plants appeared to receive the urgent message that and protected themselves by producing toxic chemicals on their leaves to fend off predators like caterpillars.

However, new research, published in the journal Trends in Plant Science, has revealed that plants not only respond to sound, but they also communicate to each other by making "clicking" sounds.

Scientists suspect that sound and vibration may play an essential role in the survival of plants by giving them information about the environment around them.

Researchers said sounds waves are easily transmissible through soil, and could be used to pick up threats like drought from their neighbors further away.

Gagliano said that the latest findings shows that the role of sound in plants has yet to be fully explored, "leaving serious gaps our current understanding of the sensory and communicatory complexity of these organisms".

In addition to other forms of sensory response, "it is very likely that some form of sensitivity to sound and vibrations also plays an important role in the life of plants," she added.
