摘　　要：大多数被子植物花瓣近轴面的锥形表皮细胞可以通过影响花瓣的光吸收、光反射和疏水性使花拥有并保持对授粉昆虫的吸引力,还可以通过为授粉昆虫与花的接触提供“扶手”而提高授粉率。由于其重要的生物学功能和独特的形态,花瓣锥形表皮细胞被用作模式系统进行细胞形态建成调控机制的研究。本文中对花瓣锥形表皮细胞形态表型的分析方法进行说明,阐述MYB转录因子、TCP转录因子、锌指转录因子、生长素、周质微管的定向排列等在花瓣锥形表皮细胞形态建成中的作用和可能的调控机制,以期为园艺植物的遗传改良提供理论参考。Most angiosperm species have conical epidermal cells on petal adaxial epidermides.These special shaped cells not only influence the light absorption,light reflection and surface hydrophobicity of petals to make flowers possess and maintain their attraction to pollinators,but also provide grips for pollinators to enhance pollination rate.Because of their important biologic functions and specific cell shape,petal conical epidermal cells are used as a model system to study the mechanisms of cell shape formation.This review explains the analytical method for morphological phenotypes of petal conical epidermal cells.Meanwhile,this review summarizes the current research results and elucidates the roles and possible regulatory mechanisms of MYB transcription factors,TCP transcription factors,zinc finger transcription factors,auxin and cortical microtubule arrays in the morphogenesis of petal conical epidermal cells.These research findings will provide theoretical references to the genetic improvement of horticultural plants.
