ABSTRACT Plant regeneration is the process during which differentiated tissues or cells can reverse alter their developmental trajectory to repair damaged form new organs. In plant process, cell wall not only functions as a foundational barrier and scaffold supporting but also influences fates identities. Cell remodeling involves selective degradation of certain components integration components. Recently, accumulating evidence has underscored importance in regeneration. Wounding signals, transmitted by transcription factors, trigger expressions genes responsible for loosening, essential tissue repair. de novo organ somatic embryogenesis, phytohormones orchestrate transcriptional regulatory network induce remodeling, promotes fate reprogramming formation. This review summarizes effects on various regenerative processes provides novel insights into future research uncharacterized roles

Abstract De novo shoot regeneration via the two-step tissue culture method is widely used for vegetative reproduction of plants and gene transformation editing. A key step in fate transition from progenitor cells (SPCs) to productive SPCs (prSPCs), which are capable differentiating into a shoot. In this study, we identified class I KNOTTED1-like homeobox (KNOX) transcription factor SHOOT-MERISTEMLESS ( STM ) as controller of, marker for, prSPCs, indicating that might serve candidate molecular tools improve de agricultural applications.
