Plant stem cells play a central role in lifelong organogenesis, growth, and regeneration by balancing self-renewal and differentiation. These pluripotent cells reside in key meristematic regions, the shoot apical meristem (SAM), root apical meristem (RAM), and lateral meristems, each governed by intricate genetic, hormonal, and epigenetic controls. Over the past two decades, substantial progress has been made in elucidating the molecular networks that sustain stem cell identity and regulate pattern formation and organ initiation. Core pathways involving transcription factors such as WUSCHEL (WUS), CLAVATA (CLV), and PLETHORA (PLT), in conjunction with phytohormonal signaling and chromatin dynamics, orchestrate stem cell function. This review synthesizes current insights into the spatial organization and molecular control of plant stem cells, explores recent advances in genetic and imaging technologies, and examines their translational potential in biotechnology and crop improvement. Finally, it highlights current knowledge gaps and outlines future research directions to deepen our understanding of plant developmental plasticity and regenerative capacity.
