摘要未受侵害的植物会对邻近受植食动物侵害的植物的挥发物做出反应，引发针对威胁的诱导防御反应。有关蛋白质表达的挥发性暴露的植物后，'植物植物信号'是稀缺的。我们专注于防御反应和蛋白质表达的利马豆植物暴露于挥发物从他们的同种被二斑叶螨（Tetranychus urticae）使用流动室。叶螨卵的数量显着减少的植物暴露于受侵害的植物挥发物，表明在暴露的植物防御诱导。蛋白质组学分析表明，两个蛋白质与光合作用和一个未知的蛋白质表现出轻微的显着减少和增加，分别。这些结果表明，挥发物引起的诱导防御基本上是独立的主要蛋白质的变化。
Abstract Non-infested plants respond to volatiles from neighboring herbivore-infested plants, triggering induced defence responses against the threat. Information about protein expression in volatile-exposed plants after the ‘plant–plant signalling’ is scarce. We focused on the defence response and the protein expression of lima bean plants exposed to the volatiles from their conspecifics infested by the two-spotted spider mites (Tetranychus urticae) using a flow chamber. The number of eggs of spider mite was significantly reduced on the plants exposed to infested plant volatiles, suggesting defence induction in the exposed plants. A proteomic analysis on the volatile-exposed plants showed that two proteins associated with photosynthesis and an unknown protein showed a marginally significant decrease and increase, respectively. These results suggest that the induced defence caused by volatiles is essentially independent of changes in the major proteins.
