<p>ANAC071 and its homolog ANAC096 are plant-specific transcription factors required to initiate cell division during tissue reunion of incised flowering stems and hypocotyl grafting in Arabidopsis thaliana;their mechanisms remain unknown. This study showed that both ANAC071 and ANAC096 were expressed at these sites before the wound-induced cambium formation. We also found that the anac-multiple mutants significantly reduced wound-induced cambium formation in incised stems and reduced the conversion of mesophyll cells to cambium cells in an ectopic vascular cell induction culture system using Arabidopsis leaves (VISUAL). These results suggest that ANAC071 and ANAC096 are involved in the process of “cambialization,” the transformation of differentiated cells into cambium-like cells and that these cambium-like cells proliferate and repair wounded tissues during the process of tissue-reunion.</p>
