- 摘要:
- A new study shows that long-term herbivore exclusion modulates volatile-induced herbivore resistance in tall goldenrod, thus providing evidence for herbivory driving the evolution of volatile-mediated plant–plant interactions in nature. When plants are attacked by herbivores, they start releasing distinct sets of volatiles. These volatiles can repel and intoxicate herbivores, attract herbivore natural enemies, and trigger defensive reactions in non-attacked tissues and plants. Thus, plants not only release but also perceive volatiles as warning cues. Although volatile-mediated plant–plant interactions are likely to be common in nature, their adaptive significance is still under debate. A new study by Aino Kalske, Kaori Shiojiri, André Kessler and colleagues, published in this issue of Current Biology, takes an important step in this direction by showing that herbivore exclusion over 12 years does not reduce the overall capacity of volatile-mediated herbivore resistance in tall goldenrod, but instead strengthens volatile-mediated interactions within genetically identical individuals.
