Glutathione accelerates the cell cycle and cellular reprogramming in plant regeneration.

The plasticity of plant cells underlies their wide capacity to regenerate, with increasing evidence in plants and animals implicating cell-cycle dynamics in cellular reprogramming. To investigate the cell cycle during cellular reprogramming, we developed a comprehensive set of cell-cycle-phase markers in the Arabidopsis root. Using single-cell RNA sequencing profiles and live imaging during regeneration, we found that a subset of cells near an ablation injury dramatically increases division rate by truncating G1 phase.
