But only during 1934 to 1939, a foundation of plant tissue culture was laid down by three scientists (Gauthret, White and Nobecourt) due to discovery of plant growth regulators such as auxins and vitamins. This concept was experimentally tested by Haberlandt who gave the idea of culturing plant cells. The essential point as far as plant cell culture is concerned is that, due to this plasticity and totipotency, specific media manipulations canbe used to direct the development of plant cells in culture.

This technique is also called micropropagation. bipolar structure having shoot and root) from the callus is called embryogenesis. Formation of new organs from the callus under the influence of auxin and cytokinin is called morphogenesis. The inherent potential of any living plant cell to develop into entire organism is called totipotency. Plant tissue culture is defined as culturing plant seeds, organs, explants, tissues, cells, or protoplasts on a chemically defined synthetic nutrient media under sterile and controlled conditions of light, temperature, and humidity.
