Abstract
Trichomes, one of the epidermal structures of medicinal plants, can be divided into two types according to whether they have a secretory function: glandular trichomes (GTs) and nonglandular trichomes (non-GTs) (Yu 2020). This article mainly elaborates on medicinal plant GTs because the tips of non-GTs lack synthesis and storage cells and do not synthesize and accumulate secondary metabolites. GTs, as an important epidermal tissue, are responsible for pollination and protection (Champagne and Boutry 2016). Some plant GTs release volatile compounds in the air. Some of these compounds are attractants for pollinators, some are repellents for herbivores and ineffective pollinators, and some are even attractants for natural enemies of herbivores (Jacek et al. 2018, Giuliani et al. 2020). Environmental conditions and seasonal changes affect the growth and development of GTs, leading to differences in the types, density, morphology, and inclusions of GTs. These differences may be related to environmental stress and the adaptive survival of plants (Li et al. 1949, Soliman et al. 2019). There are differences in the types, density, morphology, and inclusions of GTs in different plant species; thus, GTs can be used as one of the distinguishing characteristics of medicinal plants (Zhang et al. 2016, Guesmi et al. 2019). GTs, as a secretory tissue, have the remarkable characteristics of synthesizing, modifying, and storing a variety of medicinal active ingredients and contain a great complex of secondary metabolites, including terpenes, flavonoids, alkaloids, lignose, polysaccharides, glycosides, fatty acids, proteins, and alkaloids (Balcke et al. 2017, Konarska and Łotocka 2020). These secondary metabolites accumulate in GTs and have various
毛状体是药用植物表皮结构之一,根据其是否具有分泌功能可分为腺状毛状体(GTs)和非腺状毛状体(non-GTs)两种(Yu 2020)。本文主要阐述的是药用植物GTs,因为非GTs的尖端缺乏合成和储存细胞,不合成和积累次生代谢产物。gt作为一种重要的表皮组织,具有授粉和保护作用(Champagne and Boutry 2016)。一些植物的gt释放挥发性化合物到空气中。这些化合物中有些是对传粉者的引诱剂,有些是对食草动物和无效传粉者的驱避剂,有些甚至是对食草动物天敌的引诱剂(Jacek et al. 2018, Giuliani et al. 2020)。环境条件和季节变化会影响GTs的生长发育,导致GTs的类型、密度、形态和内含物的差异。这些差异可能与环境胁迫和植物的适应性生存有关(Li et al. 1949, Soliman et al. 2019)。不同植物种类的GTs在类型、密度、形态和内含物等方面存在差异;因此,GTs可以作为药用植物的显著特征之一(Zhang et al. 2016, Guesmi et al. 2019)。gt作为一种分泌组织,具有合成、修饰和储存多种药用活性成分的显著特性,并含有大量次生代谢产物,包括萜类、黄酮类、生物碱、木糖、多糖、糖苷、脂肪酸、蛋白质和生物碱等(Balcke et al. 2017, Konarska and Łotocka 2020)。这些次生代谢物在GTs中积累,并具有多种
期刊介绍:
BIOLOGIA PLANTARUM is an international journal for experimental botany. It publishes original scientific papers and brief communications, reviews on specialized topics, and book reviews in plant physiology, plant biochemistry and biophysics, physiological anatomy, ecophysiology, genetics, molecular biology, cell biology, evolution, and pathophysiology. All papers should contribute substantially to the current level of plant science and combine originality with a potential general interest. The journal focuses on model and crop plants, as well as on under-investigated species.
