植物可以产生作为化学信息素的化合物，即改变其他生物体的发育或行为的信号，而不具有直接的生理活性。在这些化学信息素中，有与诱导防御系统相关的植物胁迫信号，这些信号可能包括自然影响植物发育的植物信息素。众所周知，植物来源的信息化学物质可以通过定殖生物，特别是病原体和昆虫害虫来利用。最近提出的外部信号尚未被证明是天然的植物信息素是一氧化氮和挥发性的茉莉酸甲酯和水杨酸。由于现在可以使用复杂的电生理技术来研究昆虫与预期的植物信息素的相互作用，信号系统的检测和表征变得容易得多，并且可以提供超出昆虫本身的信号的分子表征。除了这些研究带来的进展，植物/昆虫和植物/植物相互作用的理解，植物信号在基因表达的调节，以改善或替代的方法来保护作物或其他发育过程中的植物是潜在的有价值的。
Plants can produce compounds which act as semiochemicals, that is, signals modifying the development or behaviour of other organisms without having direct physiological activity. Among such semiochemicals are plant stress signals associated with the induction of defence systems, and these may include phytopheromones that naturally influence plant development. It is well known that plant-derived semiochemicals can be exploited by colonizing organisms, particularly pathogens and insect pests. Recently proposed external signals not yet proven as natural phytopheromones are nitric oxide and the volatile methyl esters of jasmonic and salicylic acids. Since it is now possible to use sophisticated electrophysiological techniques to investigate insect interactions with prospective phytopheromones, the detection and characterization of signalling systems has been made much easier and can provide a molecular characterization of signals that are active beyond the insects themselves. In addition to the advances these studies have brought to the understanding of plant/insect and plant/plant interactions, plant signals are potentially valuable in the regulation of gene expression for improved or alternative approaches to crop protection or for other developmental processes in plants.
