Abstract

Plants have evolved powerful regeneration abilities to recover from damage. Studies on plant regeneration are of high significance as the underlying mechanisms of plant regeneration are not only linking to the fundamental researches in many fields but also to the development of widely used plant biotechnology. Higher plants show three main types of regeneration: tissue regeneration, de novo organogenesis, and somatic embryogenesis. In this review, we summarize recent research on plant regeneration, mainly focusing on Arabidopsis thaliana and moss. New data suggest that plant hormones trigger regeneration and that several key transcription factors respond to hormone signals to determine cell-fate transition. Cell-fate transition requires genome-wide changes in gene expression, which are regulated via epigenetic pathways. Certain epigenetic factors may be recruited by transcription factors to relocate to new loci and regulate gene expression. Cross talk among hormone signaling, transcription factors, and epigenetic factors is involved in different types of plant regeneration, suggesting that elegant and complex regulatory mechanisms control which type of regeneration is triggered in plants under different circumstances. Since regeneration is initiated by wounding, identification of the wound signal is an important objective for future research.
