附报告摘要：Plants have the keen ability to respond to attacks by herbivores or pathogens attack with the production of various defense chemicals. A typical response to herbivory is the production and release of volatile organic compounds. These volatiles may serve a number of functions, such as direct toxic and repellent effects on herbivores, indirect defense through the attraction of natural enemies of the herbivore, and the volatiles can serve as signals that warn undamaged plant parts of incoming attack. It is widely recognized that plant-produced volatiles have great potential for application in agriculture. The use of companion or sentinel plants that are highly responsive or that release specific volatiles show great promise and some successes have already been booked, in particular in the context of the so-called “push-pull” strategy. Another intriguing prospect is the development of sensors that can capture the information contained in the volatile signals. For now, this may seem farfetched, but sensor technology is advancing rapidly. I will discuss the various ways in which herbivore- and pathogen-induced plant volatiles may be exploited for crop protection, with special emphasis on efforts to fully understand the specificity of inducible volatile blends.
