生物谷報道：最新一期英國《新科學(xué)家》周刊刊登一份研究報告說,，韓國科學(xué)家發(fā)現(xiàn)植物對聲音敏感,，也許今后人們可以利用聲波促進植物開花或成熟,。
韓國水原市國家農(nóng)業(yè)生物技術(shù)研究院的科學(xué)家根據(jù)植物對光和觸摸作出反應(yīng)的特性,，提出大膽假設(shè)：植物也許對聲音有反應(yīng)。
研究小組在實驗室中利用水稻開展實驗,。他們給水稻播放１４首古典樂曲,，但水稻基因?qū)@些音樂沒有任何反應(yīng),。科學(xué)家改為以特殊頻率播放一些聲音,，結(jié)果水稻中兩種基因“ｒｂｃＳ”和“Ａｌｄ”在１２５至２５０赫茲的聲波中變得更為活躍,，而在５０赫茲以下的聲波中變得更為不活躍。
研究人員說,，水稻中的“ｒｂｃＳ”和“Ａｌｄ”基因已經(jīng)被證明對光有反應(yīng),。因此，研究人員在黑暗中對水稻開展了相同聲音實驗,，結(jié)果相同,。
科學(xué)家希望今后能夠通過這項發(fā)現(xiàn)利用聲音來控制植物生長。（援引新華網(wǎng)）

Plant genes switched on by sound waves
30 August 2007 Andy Coghlan Magazine issue 2619
CAN plants hear? They all respond to light, which affects how they optimise growth and survival. Plants also have a sense of touch, allowing them to stiffen in response to wind, and a "taste" for nutrients. But whether they respond to sound is a mystery.
Now Mi-Jeong Jeong of the National Institute of Agricultural Biotechnology in Suwon, South Korea, and colleagues claim to have identified two genes in rice that respond to sound waves. They also say that the promoter of one of the sound-sensitive genes could be attached to other genes to make them respond to sound too.
The findings follow a host of similar, but unsubstantiated, claims that plants respond to sound. If the researchers are correct, they say their discovery could enable farmers to switch specific crop genes on and off, such as ones for flowering, by blasting sound into the fields. That might be cheaper ...
