Plant tissue culture
Growing the plant cells, tissues and organs on a artificial, synthetic medium under controlled conditions is called plant tissue cultures.

Plant tissue culture has become a major thrust area in plant biotechnology.

Concept
The basic concept of plant tissue cultures is totipotency, differentiation, dedifferentiation and redifferentiation.

Totipotency
The inherent potential of any living plant cell to develop into entire organism is called totipotency. This is unique to plant cells.

Differentiation
The meristematic tissue is differentiated into simple or complex tissues.

Dedifferentiation
Reversion of mature tissue into meristematic state leading to the formation of callus is called dedifferentiation.

Redifferentiation
The ability of the callus to develop into shoot or root or embryoid.
