In vitro propagation

An important application of chemicals in plant biology is their use as plant growth regulators in in vitro plant tissue culture. In vitro propagation mainly relies on two classes of plant growth regulators: cytokinins and auxins. Together, they regulate cell proliferation and differentiation and are used to induce shoot or root organogenesis. Besides natural occurring cytokinins and auxins, many synthetic compounds are identified with similar action. These small molecules provide a diversified toolbox of plant growth regulators currently available for different applications in plant tissue culture. In this chapter, an overview of the different types of cytokinins and auxins is given, including their identification and mode of action. Special attention is given to new molecules identified via chemical screens. Finally, the application of the different types of cytokinins or auxins for specific processes required in plant tissue culture is discussed.
