摘要
离体再生涉及植物激素信号应答,细胞分化、脱分化获得组织器官发生以及细胞再分裂形成特定的器官原基和分生组织等过程。激素调控是影响植物离体再生的重要因素。一些关键的启动子元件和转录因子在激素应答信号的检测和转导过程中起着重要作用,激素的控制对象通常是使细胞的形态和代谢发生转变的决定性基因,以转录因子和表观遗传因子为主,它们共同完成对全基因组基因表达的重排,实现细胞命运的转变。该文对植物离体再生中激素的诱导、应答模式和信号转导以及植物器官发生和体细胞胚胎发生过程激素的分子调控进行了综述,并概述了近年来国内外有关南瓜离体再生过程激素作用的研究,旨在为提高南瓜属作物的离体再生率提供新思路。
Regeneration in vitro involves in phytohormone perception, cell differentiation, dedifferentiation to acquire organogenic competence, and organization of cell division to form specific organ primordia and meristems. Hormone regulation is an important factor affecting plant regeneration in vitro. Some key promoter elements and transcription factors play an important role in the process of hormone-response signals detection and transduction. The control object of hormone is usually the crucial genes that change the morphology and metabolism of cells, which are mainly transcription factors and epigenetic factors. They jointly complete the rearrangement of gene expression in genome-wide, and realize cell-fate transition. This review focused on the hormone induction, response patterns, signal transduction of plant regeneration in vitro, hormone molecular regulation in plant organogenesis and somatic embryogenesis, and summarized the role of hormone in pumpkin regeneration in vitro in recent years, aiming to provide a new idea for improving the regeneration rate of Cucurbita crops in vitro.
