Seasonal changes and environmental conditions, especially temperature, significantly affect cambium activation and wood formation, affecting tree growth and adaptation. Advanced genetic and epigenome analyses have revealed the importance of DNA methylation and miRNA in regulating cambium activity. The synergistic regulation of cambium activity involves a multifaceted network of genetic, hormonal, and environmental interactions, and understanding these mechanisms provides valuable insights into tree growth and development, with important implications for forestry management and climate change adaptation. This study synthesizes findings from a variety of related studies highlighting the complex interplay of genetic, hormonal, and environmental factors in cambium regulation. Through the identification of specific genes and signaling pathways regulating auxin homeostasis such as MADS-box genes VCM1 and VCM2, the molecular regulation of secondary growth was further clarified. The aim of this study was to elucidate the molecular mechanisms of cambium formation and activity maintenance in trees, focusing on the synergistic regulation of tree stem cells in growth, development and environmental adaptation.
