摘要

植物挥发物由数千个来自多种代谢途径的分子组成,其特点是在正常环境条件下有足够的蒸气压蒸发到顶空。很多都与生态信号有关,但证据是什么?它们是如何起作用的?挥发物扩散,被风携带,可能被其他生物吸收,或暴露于大气臭氧、自由基和紫外线下降解;颜色等视觉信号不受这些复杂因素的影响(但需要视线)。远亲植物和非植物产生许多相同的挥发物,但特定的化合物和混合物可能是不同的。在这里,我对植物挥发物作为生态信号的文献进行了定量回顾,说明了一个专注于发展思想和报告原始数据的领域。本文讨论了植物挥发物的优势和限制,综述了最近的研究进展,并提出了阐明植物挥发物特定功能的初步研究的考虑。

Where, When, and Why Do Plant Volatiles Mediate Ecological Signaling? The Answer Is Blowing in the Wind.

Plant volatiles comprise thousands of molecules from multiple metabolic pathways, distinguished by sufficient vapor pressure to evaporate into the headspace under normal environmental conditions. Many are implicated as ecological signals, but what is the evidence-and how do they work? Volatiles diffuse, are carried by wind, and may be taken up by other organisms or degrade with exposure to atmospheric ozone, radicals, and UV light; visual signals such as color are not subject to these complications (but require a line of sight). Distantly related plants-and nonplants-produce many of the same volatiles, yet specific compounds and blends may be distinct. Here, I present a quantitative review of the literature on plant volatiles as ecological signals, illustrating a field that has focused on developing ideas as much as reporting primary data. I discuss advantages and constraints, review recent advances, and propose considerations for primary studies to elucidate particular functions of plant volatiles.

期刊介绍: The Annual Review of Plant Biology is a peer-reviewed scientific journal published by Annual Reviews. It has been in publication since 1950 and covers significant developments in the field of plant biology, including biochemistry and biosynthesis, genetics, genomics and molecular biology, cell differentiation, tissue, organ and whole plant events, acclimation and adaptation, and methods and model organisms. The current volume of this journal has been converted from gated to open access through Annual Reviews' Subscribe to Open program, with all articles published under a CC BY license.
