Plants generally have the highest regenerative ability because they show a high degree of developmental plasticity. Although the basic principles of plant regeneration date back many years, understanding the cellular, molecular, and physiological mechanisms based on these principles is currently in progress. In addition to the significant effects of some factors such as medium components, phytohormones, explant type, and light on the regeneration ability of an explant, recent reports evidence the involvement of molecular signals in organogenesis and embryogenesis responses to explant wounding, induced plant cell death, and phytohormones interaction. However, some cellular behaviors such as the occurrence of somaclonal variations and abnormalities during the in vitro plant regeneration process may be associated with adverse effects on the efficacy of plant regeneration. A review of past studies suggests that, in some cases, regeneration in plants involves the reprogramming of distinct somatic cells, while in others, it is induced by the activation of relatively undifferentiated cells in somatic tissues. However, this review covers the most important factors involved in the process of plant regeneration and discusses the mechanisms by which plants monitor this process.

体外植物再生的细胞，分子和生理方面。

植物通常具有最高的再生能力，因为它们显示出高度的发育可塑性。尽管植物再生的基本原理可以追溯到很多年，但是基于这些原理的细胞，分子和生理机制的理解目前仍在发展中。除了培养基成分，植物激素，外植体类型和光照等因素对外植体再生能力的显着影响外，最近的报道还证明了分子信号参与了器官发生和胚胎发生对外植体受伤，诱导的植物细胞死亡的反应。 ，以及植物激素的相互作用。然而，一些细胞行为，如体外植物再生过程中体细胞克隆变异的发生和异常，可能与对植物再生功效的不利影响有关。对过去研究的回顾表明，在某些情况下，植物中的再生涉及不同体细胞的重编程，而在另一些情况下，它是由体组织中相对未分化的细胞的活化诱导的。但是，这篇综述涵盖了植物再生过程中最重要的因素，并讨论了植物监测这一过程的机制。它是由体组织中相对未分化的细胞激活而诱导的。但是，这篇综述涵盖了植物再生过程中最重要的因素，并讨论了植物监测这一过程的机制。它是由体组织中相对未分化的细胞激活而诱导的。但是，这篇综述涵盖了植物再生过程中最重要的因素，并讨论了植物监测这一过程的机制。
