title: Hormonal mechanisms for differentiation in plant tissue culture.
abstract: Cells possess extraordinary powers to organize their molecular processes not only to maintain a cell in a given steady state but also to recognize that state during differentiation. Regulation of these organizational forces appears to be under the control of chemical factors, and a hormonal concept of regulation has evolved. Hormones have been considered to act by reacting with a specific target site. This may be part of their mode of action, 0ut i would like to suggest that a hormone enters and becomes part of a total molecular resonance system. In so doing, the entire molecular system of the cell is modified.
