植物成熟细胞具有在培养条件下逆转其分化状态并产生新器官的能力。在离体器官发生过程中，通常有两个阶段，即去分化和再分化。在这些过程中，细胞经历由外在和内在因素调节的多次命运转换，这些因素与重新进入细胞周期、常染色质和异染色质之间的平衡、基因表达的重编程等有关。本文从分子、基因组和表观遗传等方面综述了植物体细胞器官再生机制的研究进展，旨在为植物离体器官发生过程中细胞命运转换机制的研究提供重要信息。
Plant mature cells have the capability to reverse their state of differentiation and produce new organs under cultured conditions. Two phases, dedifferentiation and redifferentiation, are commonly characterized during in vitro organogenesis. In these processes, cells undergo fate switch several times regulated by both extrinsic and intrinsic factors, which are associated with reentry to the cell cycle, the balance between euchromatin and heterochromatin, reprogramming of gene expression, and so forth. This short article reviews the advances in the mechanism of organ regeneration from plant somatic cells in molecular, genomic and epigenetic aspects, aiming to provide important information on the mechanism underlying cell fate switch during in vitro plant organogenesis.
