  1. The volatiles from damaged plants induce defense in neighboring plants. The phenomenon is called plant–plant communication, plant talk, or plant eavesdropping. Plant–plant communication has been reported to be stronger between kin plants than genetically far plants in sagebrush.
  2. Why do plants distinguish volatiles from kin or genetically far plants? We hypothesize that plants respond only to important conditions; the induced defense is not free of cost for the plant. To clarify the hypothesis, we conducted experiments and investigations using goldenrod of four different genotypes.
  3. The arthropod community on tall goldenrods were different among four genotypes. The response to volatiles was stronger from genetically close plants to the emitter than from genetically distant plants from the emitter. The volatiles from each genotype of goldenrods were different; and they were categorized accordingly. Moreover, the arthropod community on each genotype of goldenrods were different.
  4. Synthesis: Our results support the hypothesis: Goldenrods respond to volatiles from genetically close plants because they would have similar arthropod species. These results are important clues elucidating adaptive significance of plant–plant communication.

高大黄花上的植物-植物交流和食草动物群落

  1. 受损植物的挥发物会引起邻近植物的防御。这种现象被称为植物间交流、植物谈话或植物窃听。据报道,在山艾树中,亲缘植物之间的植物 - 植物交流比遗传距离远的植物更强。
  2. 为什么植物能将挥发物与近亲或基因相距较远的植物区分开来?我们假设植物只对重要条件作出反应;诱导防御对工厂来说不是免费的。为了阐明这个假设,我们使用四种不同基因型的一枝黄花进行了实验和调查。
  3. 高大黄花节肢动物群落在四种基因型之间存在差异。与基因距离较远的植物相比,基因上距离发射器较近的植物对挥发物的反应更强。各基因型黄花的挥发物不同;并相应地对它们进行了分类。此外,每个基因型的黄花的节肢动物群落都不同。
  4. 综合:我们的结果支持了这个假设:金黄对来自基因接近的植物的挥发物有反应,因为它们会有相似的节肢动物物种。这些结果是阐明植物-植物交流适应性意义的重要线索。
