摘要:

银杏为银杏科银杏属国家一级保护孑遗植物,具有较高的观赏、经济和药用价值。萜内酯作为银杏叶中最重要的药用活性成分之一,具有抗登革热、抗炎、抗癌和抗氧化特性,对血小板活化因子受体有强大的特异性抑制作用,是治疗阿尔兹海默病的有效制剂,故而在银杏优良树种的选育过程中,萜内酯含量是极为重要的考量指标。本文深入探讨了萜内酯生物合成调控网络,从甲基赤藓糖醇4-磷酸(MEP)途径和甲羟戊酸(MVA)途径出发,全面综述了已鉴定的20个结构基因、5类关键转录因子(MYB、WRKY、bZIP、bHLH和AP2/ERF)以及2类非编码RNA(miRNA和lncRNA)对萜内酯合成的正向或负向调控作用。同时,系统分析了环境因素(光照、温度、水分、养分等)和植物激素(ABA、SA、MeJA、IAA、ETH、GA3、CCC等)对萜内酯合成的间接影响,明确了紫外照射、适度干旱等外部环境刺激,以及外源施加MeJA、SA、CCC等激素可显著提升银杏叶片中萜内酯含量,而土壤肥力、种植密度以及病虫害等因素也对其积累存在一定影响。最后,本文提出构建“内部基因调控”与“外部环境优化”协同策略,以促进银杏萜内酯含量,旨在为后续的生产实践和科学研究提供具有重要参考价值的理论指导,进而实现银杏药用价值和商业价值的提升。

Abstract:

: Ginkgo biloba is a national first-class protected relict plant belonging to the genus Ginkgo in the family Ginkgoaceae, boasting high ornamental, economic, and medicinal values. Terpene trilactones, as one of the most significant bioactive components in G. biloba leaves, exhibit anti-dengue, anti-inflammatory, anti-cancer, and antioxidant properties. Specifically, they demonstrate a potent and specific inhibitory effect on platelet-activating factor receptors and serve as effective agents for the treatment of Alzheimer's disease. Consequently, the content of terpene trilactone is considered a crucial selection index in the breeding of superior G. biloba varieties. This paper provides a comprehensive review of the regulatory network underlying the biosynthesis of terpene trilactones. Based on the Methylerythritol 4-phosphate (MEP) and Mevalonate (MVA) pathways, the positive and negative regulatory roles of 20 identified structural genes, five categories of key transcription factors (including MYB, WRKY, bZIP, bHLH, and AP2/ERF), and two types of non-coding RNAs (miRNA and lncRNA) are thoroughly discussed. Furthermore, the indirect effects of environmental factors (such as light, temperature, water, and nutrients) and plant hormones (including ABA, SA, MeJA, IAA, ETH, GA3, and CCC) on the biosynthesis of terpene trilactones are systematically analyzed. It is clarified that external environmental stimuli, such as ultraviolet radiation and moderate drought, as well as the exogenous application of hormones, such as MeJA, SA, and CCC, can significantly enhance the accumulation of terpene trilactones in G. biloba leaves. Additionally, the factors such as soil fertility, planting density, and the occurrence of pests and diseases also influence their accumulation. Finally, a synergistic strategy integrating “endogenous gene regulation” and “exogenous environmental optimization” is proposed to promote the content of terpene trilactones. This review aims to provide theoretical guidance with significant reference value for future production practices and scientific research, thereby maximizing the medicinal and commercial potential of G. biloba.
