摘要
腋生分生组织（AM）位于叶腋，可以建立新的生长轴。其邻近细胞已经分化，而腋生分生组织中的未分化细胞则赋予了腋生分生组织与芽顶端分生组织相同的发育潜力。因此，AM是研究植物干细胞命运维持的绝佳系统。在本综述中，我们总结了目前有关AM起源的知识。最近的研究结果表明，AM来源于在叶腋中维持的干细胞系。本综述涉及 AM 祖细胞的命运维持、再活化和分生组织的建立。我们还重点介绍了将转录因子、植物激素和表观遗传调控与AM起源联系起来的最新研究成果。
Control of cell fate during axillary meristem initiation.
Axillary meristems (AMs) are located in the leaf axil and can establish new growth axes. Whereas their neighboring cells are differentiated, the undifferentiated cells in the AM endow the AM with the same developmental potential as the shoot apical meristem. The AM is, therefore, an excellent system to study stem cell fate maintenance in plants. In this review, we summarize the current knowledge of AM initiation. Recent findings have shown that AMs derive from a stem cell lineage that is maintained in the leaf axil. This review covers AM progenitor cell fate maintenance, reactivation, and meristem establishment. We also highlight recent work that links transcription factors, phytohormones, and epigenetic regulation to AM initiation.
