The heterodimeric transcription factor complex ERF115-PAT1 grants regeneration competence.

Regeneration of a tissue damaged by injury represents a physiological response for organ recovery. Although this regeneration process is conserved across multicellular taxa, plants appear to display extremely high regenerative capacities, a feature widely used in tissue culture for clonal propagation and grafting. Regenerated cells arise predominantly from pre-existing populations of division-competent cells; however, the mechanisms by which these cells are triggered to divide in response to injury remain largely elusive.
