Organogenesis in vitro consists of many aspects such as phytohormone perception, dedifferentiation of differentiated cells to acquire organogenic competence, re-entry of quiescent cells into cell cycle, and organization of cell division to form specific organ primordia and meristems. Some of elementary processes and essential genes involved in this composite phenomenon are being identified largely through genetic analysis with various types of mutants including temperature-sensitive and activation-tagged ones.
体外器官发生包括许多方面，如植物激素感知、分化细胞去分化以获得器官发生能力、静止细胞重新进入细胞周期以及细胞分裂组织形成特定的器官原基和分生组织。参与这一复合现象的一些基本过程和关键基因主要是通过对包括温度敏感型和激活标签型在内的各种突变体进行遗传分析来确定的。
