What is redifferentiation in plant tissue culture?

Redifferentiation:

1. After dividing up to a certain phase, the plant cells undergo maturation by the process of differentiation and stop dividing any further.
2. When these mature cells regain their property to divide, the process is called dedifferentiation (to regain their dividing capacity).
3. After dedifferentiation, the mature cells become meristematic cells leading to the formation of callus.
4. When these secondary meristematic cells again lose their property to divide, they are said to undergo redifferentiation.
5. The process of development of an entire plant from cells of callus is also termed redifferentiation in plant tissue culture.
