Plant trichomes are special structures that originate from epidermal outgrowths. Trichomes play an important role in plant defense against pests and diseases, and possess economic and medicinal values. Study on molecular mechanism of plant trichomes will contribute to the molecular design breeding and genetic improvement of crops. In recent years, the regulation mechanism of trichome development has been basically clarified in the model plant Arabidopsis thaliana, while great progresses are also found in other plant species. In this review, we focus on the developmental regulation of trichome formation from gene and phytohormones levels in Arabidopsis and cotton (with unicellular trichomes), as well as in tomato and Artemisia annua (with multicellular trichomes). The research progress associated with trichomes is also introduced in other typical monocotyledons and dicotyledons. Finally, the research and application of plant trichomes are prospected.
植物毛状体是起源于表皮突出物的特殊结构。毛状体在植物抵御病虫害方面发挥着重要作用，并且具有经济和药用价值。对植物毛状体分子机制的研究将有助于作物的分子设计育种和遗传改良。近年来，在模式植物拟南芥中，毛状体发育的调控机制已基本阐明，在其他植物物种中也取得了重大进展。在本综述中，我们重点关注拟南芥和棉花（具有单细胞毛状体）以及番茄和青蒿（具有多细胞毛状体）中从基因和植物激素水平对毛状体形成的发育调控。其他典型单子叶植物和双子叶植物中与毛状体相关的研究进展也将被介绍。最后，对植物毛状体的研究和应用进行了展望。
