Plant tissue culture is the in vitro manipulation of plant cells and tissues under aseptic conditions. Gottlieb Haberlandt pioneered the plant tissue culture concept in the first decade of 20th century (1902). Remarkable progress has been made in plant tissue culture since then. It can be used to initiate cell division, regenerate lost organs or whole transformed plants from transformed cells or tissue. Plant hormones, Cytokinin, Auxin and their derivatives are known to play a key role in promoting cell division. There is considerable interest and research in progress worldwide for the commercial exploitation of plant tissue culture in areas viz. Agriculture, Horticulture, Forestry etc. Many therapeutic agents have also been produced by the commercial exploitation of plant cell and tissue culture technology.
