It plays an important role in plant defense against biotic and abiotic stress. In the meantime, its secretions, containing various secondary metabolites, have been exerting a considerable socioeconomic impact. - - - 植物表皮毛状体是由表皮细胞发育而来的特殊结构附属物，以不同的形态广泛存在于植物中，在植物防御**生物和非生物胁迫**中产生作用，其分泌物（含各种次级代谢物）具有不可忽视的社会经济价值。
