| Outline of Final Research Achievements |
Wounding stress induces cellular reprogramming in regeneration but the molecular mechanisms underlying this control remain largely unknown. In this study we aimed at uncovering the transcriptional mechanisms that regulate wound-induced cellular reprogramming in plants. Using the Arabidopsis tissue culture system, we revealed the early transcriptional cascade activated by wounding. We also showed that the activity of this early transcriptional network is regulated by SUMO-mediated post-translational mechanisms. Using the Arabidopsis mesophyll protoplast system, we also demonstrated that the part of the wound-induced transcriptional cascade is also required for the reprogramming from differentiated plant cells.
