The ability to predict future risks is essential for many organisms, including plants. Plants can gather information about potential future herbivory by detecting volatiles that are emitted by herbivore-attacked neighbors. Several individual volatiles have been identified as active danger cues. Recent work has also shown that plants may integrate multiple volatiles into their defense responses. Here, I discuss how the integration of multiple volatiles can increase the capacity of plants to predict future herbivore attack. I propose that integration of multiple volatile cues does not occur at the perception stage, but may through downstream early defense signaling and then be further consolidated by hormonal crosstalk. Exploring plant volatile cue integration can facilitate our understanding and utilization of chemical information transfer.

将多种挥发性线索整合到植物防御反应中

预测未来风险的能力对于包括植物在内的许多生物体至关重要。植物可以通过检测被食草动物攻击的邻居释放的挥发物来收集有关潜在的未来食草动物的信息。几种单独的挥发物已被确定为主动危险信号。最近的研究还表明，植物可能会将多种挥发物整合到它们的防御反应中。在这里，我讨论了多种挥发物的整合如何提高植物预测未来食草动物攻击的能力。我建议多个易失性线索的整合不会发生在感知阶段，但可能通过下游的早期防御信号，然后通过激素串扰进一步巩固。探索植物挥发性线索整合可以促进我们对化学信息传递的理解和利用。
