从体细胞分化细胞再生完整植株的可能性强调了植物发育的可塑性。再生过程中的细胞类型重新指定可以在成体组织中作为损伤、外部或内部刺激的变化或位置信息的变化的结果而诱导。然而，在许多植物物种中，在器官再生之前转换成体细胞的发育程序是困难的，特别是在森林物种中。除了其对森林生产力的影响，细胞分化的灵活性的基本信息是必要的细胞分化和植物发育的表观遗传控制的全面理解。研究成年细胞中特定基因表达的调控变化，对于揭示细胞可塑性调控的基本机制具有重要意义。
The possibility of regenerating whole plants from somatic differentiated cells emphasizes the plasticity of plant development. Cell-type respecification during regeneration can be induced in adult tissues as a consequence of injuries, changes in external or internal stimuli or changes in positional information. However, in many plant species, switching the developmental program of adult cells prior to organ regeneration is difficult, especially in forest species. Besides its impact on forest productivity, basic information on the flexibility of cell differentiation is necessary for a comprehensive understanding of the epigenetic control of cell differentiation and plant development. Studies of reprogramming adult cells in terms of regulative expression changes of selected genes will be of great interest to unveil basic mechanisms regulating cellular plasticity.
