Plant perception of insect herbivores includes leaf vibrations caused by chewing

植物受到多种害虫的侵袭，快速检测是防御成功的关键。一种新发现的植物检测昆虫攻击的方法--感知昆虫咀嚼引起的振动--可能比其他已知的检测系统更快、更可靠。这个项目有四个目标。首先，新的检测系统将在几种植物和害虫中进行研究。第二，将开发其作用的快速筛选方法。第三，对送料振动信号的特征进行表征，这些特征对检测具有重要意义。第四，将使用机械感受器突变来识别可能检测取食振动的植物感受器的种类。这些知识将为育种人员提高植物对虫害的抵抗力提供目标。该项目将培训学生和博士后学者从事科学和与公众交流的工作。它还将培训教师在课堂上融入更多的科学知识。这项提案中植物传播的振动世界对儿童和广大公众都非常有吸引力。通过提供声学生态工具包和对教师的培训，更多的孩子将体验到科学的刺激和回报。

Plants are attacked by many kinds of insect pests, and quick detection is key to successful defense. A newly discovered way that plants can detect insect attack - sensing vibrations caused by insect chewing - is likely to be faster and more reliable than other known detection systems. This project has four goals. First, the new detection system will be studied in several kinds of plants and insect pests. Second, rapid screening methods for its action will be developed. Third, the features of the feeding vibration signal that are important to the detection will be characterized. Fourth, the kind of plant receptor likely to be detecting the feeding vibrations will be identified using mechanoreceptor mutants. This knowledge will provide targets for breeders to enhance plant resistance to insect pests. This project will train students and postdoctoral scholars for careers in science and communication with the public. It will also train teachers to incorporate more science into their classrooms. The world of plant-borne vibrations featured in this proposal is highly appealing to children and the public at large. By providing acoustic ecology kits and training to teachers, additional children will experience the excitement and rewards of science.
