中文摘要:植物毛状体来源于表皮细胞的延伸,是表皮细胞的特有结构。植物毛状体可分为腺毛和非腺毛,腺毛是具有分泌作用的毛状体,也是大量次生代谢产物的合成、储存以及释放的场所。植物腺毛常分泌不同类型的防御物质如萜类、氨基酸及苯丙烷类、酰基糖、脂肪类衍生物等,这些次生代谢物质能够保护植物免受生物和非生物胁迫,具有重要的防御作用。该文对近年来国内外有关植物腺毛的类型、防御物质的合成与调控等方面的研究进展进行综述,并重点对其合成途径、调控机理与转运机制的研究进展进行梳理,以期为防御物质的生物合成和遗传改良研究提供参考。

Advances in Synthesis, Regulation and Transportation of Defensive Substances Produced in Plant Glandular Trichomes
Abstract:Trichomes are derived from the extension of plant epidermal cells and are a unique structure. trichomes can be divided into glandular and non glandular trichomes. Glandular trichomes are secretory trichomes where a large number of secondary metabolites are synthesized, stored and released. Glandular trichomes often secrete different types of defensive substances such as terpenes, amino acids and phenylpropanes, acylsugars, fatty derivatives, etc. These secondary metabolites can protect plants from biotic and abiotic stresses and have important defensive effects. Therefore, this article summarizes the types of glandular trichomes, the synthesis and regulation of defense substances, and focuses on the study of its synthesis pathways, regulation mechanisms and transport mechanisms to provide references for the research on the biosynthesis and genetic improvement of defense substances.
