虫害诱导植物挥发物(HIPVs):从诱导到生态功能

Herbivore-induced plant volatiles: from induction to ecological functions

植物被植食性昆虫危害后,其地上和地下部分均能释放虫害诱导植物挥发物(HIPVs)。HIPVs不仅能招引植食性昆虫的天敌,而且还可对植食性昆虫和临近植物产生影响,从而调节植物、植食性昆虫、天敌三者之间的相互关系。根据最近的研究结果,主要就HIPVs的诱导物类型、虫害后植物体内的早期信号和信号传导、HIPVs的合成、释放、组成,以及其生态功能等进行了系统性的综述,并提出了今后该领域的研究方向。

In response to herbivores, leaves and roots of plants could emit herbivore-induced plant volatiles （HIPVs） which could manipulate tritrophic interactions through attracting parasitoids and predators of herbivores, and affecting behavior of herbivores and physiology of neighbouring plants. In the light of recent findings, the elicitor, early signal, signal transduction, biosynthesis, emission, composition and ecological functions of I-IIPVs were reviewed in this paper. Finally, research directions in this field in the future were suggested.
