Specialized plant cells regain stem-cell features to heal wounds

Already specified root cells are reprogrammed to correctly replace dead neighbor cells in newly discovered process of “restorative patterning” | Study published in Cell

If plants are injured, cells adjacent to the wound fill the gaps with their daughter cells. However, which cells divide to do the healing and how they manage to produce cells that match the cell type of the missing tissue has been unclear. Scientists from the Institute of Science and Technology Austria (IST Austria) have now shown that to correctly replace dead cells, neighbors to the inside of the wound re-activate their stem cell programs.
