Trichomes, hair-like specialized epidermal structures on the surface of most plant organs, play key roles in plant defense against herbivores, reducing water loss, and shielding plants from UV radiation, among other functions. Controlling trichome development and the biosynthesis of trichome-derived specialized metabolites is a common defensive strategy adopted by plants to protect themselves from environmental stresses. However, trichomes exhibit distinctive functions in different plant tissues. Fruits, being the most economically valuable organs of many horticultural plants, often have trichomes on their surface. Nevertheless, there is a notable lack of research on the regulation and function of fruit trichomes, in comparison to the extensive studies conducted on trichomes in other plant tissues. Further investigation is needed to elucidate the specific functions of fruit trichomes. The regulation of plant trichome development and the multiple roles of trichomes represent a dynamic area of plant biology with significant implications for agriculture and biotechnology. This review aims to enhance the understanding of the functions, regulatory mechanisms, and applications of fruit trichomes, emphasizing their importance in advancing agricultural sustainability and productivity.
毛状体是大多数植物器官表面毛发状的特化表皮结构，在植物防御食草动物、减少水分流失以及保护植物免受紫外线辐射等方面发挥着关键作用，还有其他一些功能。控制毛状体发育以及毛状体衍生的特化代谢物的生物合成是植物采取的一种常见防御策略，以保护自身免受环境胁迫。然而，毛状体在不同植物组织中表现出独特的功能。果实是许多园艺植物最具经济价值的器官，其表面通常有毛状体。尽管如此，与对其他植物组织中的毛状体进行的广泛研究相比，对果实毛状体的调控和功能的研究明显不足。需要进一步研究以阐明果实毛状体的具体功能。植物毛状体发育的调控以及毛状体的多种作用代表了植物生物学中一个充满活力的领域，对农业和生物技术具有重要意义。本综述旨在增进对果实毛状体的功能、调控机制和应用的理解，强调它们在促进农业可持续性和生产力方面的重要性。
