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