Adventitious Root Regeneration: Molecular Basis and Influencing Factors

Plant regeneration is a self-repair of the plant body in response to adverse conditions or damaged structures, and root regeneration allows the plant body to better adapt to its environment by supplementing the roots’ structure. Previous research has shown that adventitious roots can be made to occur from scratch in two ways. Studies that simulate adventitious root regeneration through natural conditions allow the regeneration process to be broadly divided into three stages: the perception of early signals, the massive accumulation of auxin, and the transformation of cell fate. The strength of regeneration, in turn, is influenced by wounding, stress, hormones, etc. This study mainly reviews the molecular mechanisms of de novo adventitious roots and discusses how the environment, hormones, and its own development in Arabidopsis thaliana.
