植物的不定芽再生过程涉及众多基因及其互作。细胞分裂素诱导体细胞启动、启动的体细胞进行分裂和由此引发的茎分生组织发育是这一过程中的3个重要步骤。探讨这3个步骤的相关基因表达及其关系, 有助于揭示植物不定芽再生的分子调节机制。文章就这些步骤所涉及的分子调节过程的研究成果作一评述。

In vitro shoot regeneration is a developmental process that multiple genes and their interactions are involved in. Initiation of somatic cells stimulated by cytokinin, division of the initiated somatic cells and succeeding shoot meristem development are three key steps in the process. Therefore, exploration of gene expression and their interactions involved in these steps will shed light on our understanding of the molecular mechanism for regulation of plant in vitro shoot regeneration. Here we reviewed the research results of molecular regulation process involved in these steps.
