1、Munching vegetables, you have to care aboutthe feelings of vegetables?在对拟南芥属植物进行检测之后,科学家得出了这一结论。研究指出拟南芥属植物能够根据咀嚼方式和口水判断自己被何种昆虫啃食。After Arabidopsis plants were detected, scientists have come to this conclusion. Research indicates that Arabidopsis plants can according to chewing and saliva by eating i
2、nsects which determine their own.美国密苏里州大学高级研究科学家海蒂-阿珀尔在接受华盛顿邮报采访时表示:“拟南芥的叶片对毛虫的咀嚼和蚜虫的吮吸会做出不同的反应,这一点并不令我们感到非常吃惊。真正令我们感到吃惊的是,拟南芥对每一种毛虫的咀嚼和蚜虫的吮吸做出的反应存在巨大差异。拟南芥有能力分辨昆虫,知道自己正被哪种昆虫攻击。”University of Missouri senior research scientist Heidi - O pearl in an interview with the Washington Post, said: the leave
3、s of Arabidopsis thaliana to Caterpillar chewing and aphids sucking will make different responses, this does not make us feel very surprised. Really surprised us is that Arabidopsis of a caterpillar chewing and aphids sucking reaction, there is a huge difference. Arabidopsis is able to distinguish b
4、etween insects, know is what kind of insect attack.研究过程中,阿珀尔教授给菜粉蝶幼虫和甜菜夜蛾喂食拟南芥。根据她的预测,随着昆虫的进食,拟南芥能够通过咀嚼和吮吸的差异分辨出自己究竟被菜粉蝶幼虫还是甜菜夜蛾攻击。此外,她还认为这种植物有能力分辨多种昆虫,甚至在不同昆虫同时啃食它们的情况下也是如此。为了验证自己的理论,阿珀尔将昆虫吃过的拟南芥收集起来,而后在实验室提取基因并冷冻。In the course of the study, Professor Perle, to Pieris rapae larvae and beet armyworm
5、 feeding of Arabidopsis thaliana. According to the prediction of her, with insect eating, Arabidopsis thaliana can by chewing and sucking the differences distinguish what is Pieris rapae larvae or beet armyworm attack. In addition, she also believes that the plants have the ability to distinguish a
6、variety of insects, even in different insects while eating food they. In order to validate his theory, pearl will insect eaten Arabidopsis collected. Then in the laboratory extraction gene and frozen.植物会采取一系列方式进行防御,例如释放辣味和腐臭味。这些防御手段均在基因中得到表达。通过基因分析,阿珀尔发现拟南芥能够感知到毛虫流口水,所采取的防御方式与感知到蝴蝶不同。对于不同的昆虫,植物会做出不同
7、的反应,说明植物能够分辨昆虫,知道自己正遭受何种昆虫攻击。The plant will take a series of defense, such as the release of the spicy taste and smell. These defences were in genes are expressed. Through genetic analysis, pearl found that Arabidopsis thaliana can perceive caterpillar drooling, taken by the defense style and percep
8、tion to different butterfly. For different insects, the plant will make different responses, that plants can distinguish insect, know that they are being what insect attack.阿珀尔希望这项研究发现能够帮助科学家培育出天生就对昆虫具有抵抗力的植物,而不是喷洒杀虫剂。她的研究立基于2014年的一项研究,后者发现植物能够分辨出附近的声响,例如进食声,而后对所处环境中的各种威胁做出响应。O perle hopes this stud
9、y found that can help scientists have bred naturally would have the plant resistance to insects, rather than spraying of insecticides. Her study is made based on a study in 2014, which is found in plants are able to distinguish the near sound, such as eating sound, and the various threats to the env
10、ironment in which to respond研究论文合著者莱克斯-科克罗夫特指出:“我们得出了一项引人注目的发现:当拟南芥感知到不同的振动例如微风产生的振动或者不同昆虫发出的声响,哪怕与毛虫进食产生的振动拥有一些相同的声学特征,拟南芥的化学防御也不会加强。这一现象说明拟南芥有能力区分进食振动和其他常见的环境振动源。”Study co-author Lex Cockcroft said: we get a remarkable discovery: when the Arabidopsis perceives to different vibration - such as bree
11、ze vibration, or from different insect sound, even and the caterpillars eating produce vibration possess some of the same acoustic features in Arabidopsis chemical defense is never, and has enhanced. This phenomenon indicates that Arabidopsis has the ability to distinguish between eating vibration and other common environmental vibration source.生词defense difens vt.谋划抵御; Distin
