Abstract

The article focuses on the initiation of axillary meristems (AMs) in seed plants, which are postembryonic shoot apical meristems (SAMs) formed in leaf axils that enable lateral branching and influence plant architecture and crop yield. Recent research, primarily in Arabidopsis thaliana, has clarified that AMs originate from a population of meristematic cells detached from the embryonic SAM, with the SHOOT MERISTEMLESS (STM) gene playing a central role in maintaining these cells. AM initiation involves a multistep regulatory network of transcription factors, microRNAs, and phytohormones, culminating in the establishment of a functional SAM through a WUSCHEL (WUS)–CLAVATA3 (CLV3) feedback loop activated by cytokinin signaling. This system provides a valuable model for studying stem cell fate, meristem formation, and plant developmental plasticity.
