植物具有显著的再生能力,能够在体内和体外替换受损器官或形成新的器官和个体,这是植物发育可塑性和农业实践的基础。植物的再生能力高度依赖于体细胞的全能性或多能性,体细胞的命运由植物激素、创伤和其他刺激来指导。最近的研究表明,这两种类型的细胞重编程参与了植物体内外再生过程中细胞多能性的获得。本文综述了植物细胞多能性获得的细胞起源、分子特征、遗传和表观遗传调控等方面的最新研究进展,重点介绍了不同刺激激活细胞重编程的分子框架及其在植物再生生物技术中的应用潜力。
Plants have a remarkably regenerative capability to replace the damaged organs or form the new organs and individuals both in vivo and in vitro, which is fundamental for their developmental plasticity and the agricultural practices. The regenerative capacities of plants are highly dependent on the totipotency or pluripotency of somatic cells, whose fates are directed by phytohormones, wounding, and other stimuli. Recent studies have revealed that the two types of cellular reprogramming are involved in the acquisition of cell pluripotency during plant in vitro and in vivo regeneration programs. This review focuses on the recent advances of the cellular origin, molecular characteristic, and genetic and epigenetic regulations of cell pluripotency acquisition in plants, highlighting the molecular frameworks of cellular reprogramming activated by diverse stimuli and their possible potentials in regeneration-based plant biotechnologies.
