绿叶c6挥发物是草食诱导植物挥发物中最重要的挥发物之一。它们在调节食草动物和天敌的行为,以及触发植物间的交流以防止进一步的攻击方面发挥着重要作用。近年来,伤口诱导的无所不在(Z)-3-己烯醇是一种由脂氧合酶/HPL途径合成的c6 -醇,被证明是三营养相互作用中食草动物驱避/吸引和天敌吸引最重要的信息化学物质,并可诱导邻近未受攻击植物的基因表达。虽然(Z)-3-己烯醇在植物直接防御和间接防御中的作用存在冲突,但其在间接防御和启动效应中的积极作用是一致的。因此,该化合物可用于开发新的害虫防治策略。
Green leaf C6-volatiles are among the most important herbivore-induced plant volatiles (HIPVs). They play important roles in mediating the behavior of herbivores and their natural enemies, and in triggering the plant-plant communication to prevent further attacks. Recently, wound-induced ubiquitous (Z)-3-hexenol, a C6-alcohol synthesized in the lipoxygenase/HPL pathway, was proved to be the most important infochemical for the herbivore repellence/attraction and natural enemy attraction in tritrophic interactions, as well as for the induction of gene expression in neighboring unattacked plants. In spite of the conflict functions of (Z)-3-hexenol in direct and indirect plant defenses, its positive roles in the indirect defense and the priming effect are consistent. Therefore, this compound can be used to develop novel insect pest control strategies.
