Plants emit an overabundance of volatile compounds, which act in their producers either as appreciated attractants to lure beneficial animals or as repellent toxins to deter pests in a species-specific and concentration-dependent manner. Plants have evolved solutions to provide sufficient volatiles without poisoning themselves. Uridine-diphosphate sugar-dependent glycosyltransferases (UGTs) acting on volatiles is one important part of this sophisticated system, which balances the levels of bioactive metabolites and prepares them for cellular and long-distance transport and storage but enables the remobilization of disarmed toxins for the benefit of plant protection. This review provides an overview of the research history of glycosidically bound volatiles (GBVs), a relatively new group of plant secondary metabolites, and discusses the role of UGTs in the production of GBVs for plant protection.
植物会释放出大量挥发性化合物，这些化合物在植物体内以特定物种和浓度依赖的方式发挥作用，既可以作为有益动物的引诱剂，也可以作为驱虫剂的毒素。为了在不毒害自身的情况下提供足够的挥发性物质，植物已经进化出了解决方案。作用于挥发性物质的尿苷二磷酸糖依赖性糖基转移酶（UGTs）是这一复杂系统的重要组成部分，它可以平衡生物活性代谢物的水平，并为它们的细胞内和长距离运输和储存做好准备，同时还可以使解毒毒素重新用于植物保护。本文综述了糖基结合挥发物（GBVs）的研究历史，这是一类相对较新的植物次生代谢物，并讨论了 UGTs 在植物保护中产生 GBVs 方面的作用。
