【摘要】 植物表皮毛是植物表皮细胞形成的一种特殊毛状体,对植物自身起到保护与调节作用。目前植物表皮毛已在拟南芥(Arabidopsis thaliana)、番茄(Lycopersicon esculentum)、水稻(Oryza sativa)、烟草(Nicotiana tabacum)及青蒿(Artemisia carvifolia)等多种经济作物与药用植物中展开研究。拟南芥表皮毛细胞结构简单,目前对其研究最为深入和全面,为后续其它植物的研究提供了指导。自然界中,表皮毛是植物内部与外部环境间的一道天然屏障,主要通过物理防御和分泌化学物质提高植物对不良环境的抗性。当前对于表皮毛研究已从细胞层面发展到分子机制层面。该研究就植物表皮毛的类型、功能、生理生化特点、分子调控研究4个方面进行总结,为今后植物表皮毛的研究提供理论基础,同时为植物改良及育种提供指导。更多还原

【Abstract】 Plant trichome is a special trichomes form by plant epidermal cells.It protected and regulated plants themselves.At present,the research on the trichomes of plants was widely distributed in various economic crops and medicinal plants such as Arabidopsis thaliana,Lycopersicon esculentum,Oryza sativa,Nicotiana tabacum,and Artemisia carvifolia etc.Trichomes of Arabidopsis had a simple structure.Therefore,its research was the most in-depth and comprehensive,and it also provided guidance for the subsequent research of other plants.In nature,trichome was a natural barrier between the interior of the plant and the external environment,which enhanced plant resistance to adverse environments mainly through physical defense and secretion of chemicals.The current research on trichome had evolved from the cellular level to the molecular mechanism.This review summarized the four aspects of the type,function,physiological and biochemical characteristics and molecular regulation of plant trichomes,and provided a theoretical basis for the study of plant trichomes in the future,and provided guidance for plant improvement and breeding.更多还原
