4. Cytodifferentiation Cell differentiation, mainly emphasis on vascular differentiation, tracheary element differentiation, etc. Dedifferentiation The phenomenon of mature cells reverting to a meristematic state and forming undifferentiated callus tissue. Redifferentiation The ability of the component cells of the callus to differentiate into a whole plant or organ.
