Trichomes (/ ˈ t r aɪ k oʊ m z, ˈ t r ɪ k oʊ m z /; from Ancient Greek τρίχωμα (tríkhōma) ' hair ') are fine outgrowths or appendages on plants, algae, lichens, and certain protists. They are of diverse structure and function. Examples are hairs, glandular hairs, scales, and papillae.

2021年2月1日 · Trichomes play a key role in the development of plants and exist in a wide variety of species. In this paper, it was reviewed that the structure and morphology characteristics of trichomes, alongside the biological functions and classical regulatory mechanisms of trichome development in plants.

This review examines how leaf trichomes influence leaf physiological responses to abiotic environmental drivers. Leaf trichomes are known to modulate leaf traits, particularly radiation absorptance, but studies in recent decades have demonstrated that trichomes have a more expansive role in the plan …

表皮毛 (Trichome)由植物地上部分表皮细胞发育而来，是一种特化的毛状结构，不仅可以保护植物抵抗生物和非生物胁迫，还具有很高的经济和药用价值 [1]。 表皮毛根据其是否具有分泌能力分为非腺毛和腺毛两种 [2]。 非腺毛存在于大多数的被子植物以及部分裸子植物和苔藓植物中，不具备合成和储存次级代谢产物的能力，部分可以抵御食草动物和昆虫的侵害，例如棉花表皮毛 (棉纤维)在抵抗棉铃象鼻虫等害虫时起重要作用 [3]。 腺毛可以合成、分泌或储存多种次生代谢产物 …

2025年2月5日 · These data provide insights into how mature leaves function as nutrient sensors that control trichome formation within distant developing leaves through a nutrient sensor–relay mechanism. Our findings uncover both a previously unidentified, nutrient sensing–regulatory mechanism and the cognate underpinning molecular architecture.

2021年7月1日 · Plant glandular trichomes (GTs) are epidermal outgrowths with the capacity to biosynthesize and secrete specialized metabolites, that are of great scientific and practical significance. Our...

2025年3月29日 · Trichomes, the hair-like epidermal outgrowth appendages on the leaf surface of nearly all land plant, are generally classified as either glandular or non-glandular (Hulskamp et al., 1998, Wagner et al., 2004).They exhibit diverse structures in terms of cell numbers (e.g., unicellular and multicellular), size, and morphology (Wagner et al., 2004).As an outmost biophysical barrier, trichomes ...

2024年1月1日 · Some plants possess abundant trichomes on their leaf surfaces, which contribute to the thickening of the boundary layer between the plant and the environment. This, in turn, helps to reduce heat and water loss. Trichomes serve as a protective barrier between the plant's epidermal tissues and the external environment.

Valkama E, Koricheva J, Ossipov V, Ossipova S, Haukioja E, Pihlaja K (2005) Delayed induced responses of birch glandular trichomes and leaf surface lipophilic compounds to mechanical defoliation and simulated winter browsing.

2022年7月14日 · In this study, we investigated the effects of water-deficit stress on the leaf anatomical traits, physiological traits, and stem starch content in Quercus acutissima Carruth and Quercus serrata Murray by subjecting their seedlings to well-watered (WW) and water-deficit stress (WS) treatments.
