Many gardeners believe that "talking" to their plants helps them grow---it turns out that _ may not be crazy after all. According to the scientists from the University of Exeter, plants may keep communicating with each other through a secret "unseen" language. For their experiment, the scientists picked a cabbage plant that is known to send out a gas when its surface is cut. In order to get video evidence of the communication, they changed the cabbage gene by adding the protein---luciderase , which is what makes fireflies  glow in the dark. When the changed cabbage plant was in full bloom, they cut a leaf off with a pair of scissors, and almost immediately, thanks to the luciderase, they could see the plant sending out "methyl jasmonate ". While this was a known fact, what was surprising was the fact that the minute this gas began to give out, the nearby cabbage plants seemed to sense some kind of danger and started to send out a gas that they normally have to keep predators  like caterpillars  away. What the scientists are not sure is whether the plants are trying to warn the other leaves or the near plants about the danger---something that will require further research However, the team, which is led by Professor Nick Smirnoff, is quite excited about the findings because this is the first time it has been proved that plants do not live a passive life, but actually move, sense and even communicate with each other. However, before you get all concerned, they are quite sure that plants do not feel the pain when they are cut, since they do not have nerves---so go ahead and bite into that juicy carrot! According to the experiment, plants   _  .
