　　　　　Many gardeners believe that“talking”to their plants helps them grow−−it turns out that they may not be crazy at 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 luciferase(荧光素酶)，which is what makes fireflies(萤火虫)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 luciferase,they could see the plant sending out“methyl jasmonate (茉莉酸甲酯)”.
　　　　　While this was a known fact,what was surprising was the fact that the minute this gas began to be releaseD,the nearby cabbage plants seemed to detect some kind of danger and started to send out a gas that they normally have to keep enemies like caterpillars(毛虫)away.
　　　　　What the scientists are not sure is whether the plants are trying to warn the other leaves or the near plants of 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 liKe,but actually move,sense and even communicate with each other.
