Calcium Mediation of Cytokinin-Induced Cell Division

Abstract

Cytokinins are a class of plant hormones that are defined by their ability, in the presence of optimal auxin, to initiate cell division in tobacco pith culture (Skoog et al., 1965). For a variety of reasons it seems plausible that cytokinins exert at least part of their effect through modulation of intracellular calcium ion concentration ([Ca2+]i.). An argument in favor of this hypothesis can be made by integrating the literature on cytokinin stimulation cell division, mitotic regulation by Ca2+, and cytokinin modulation of Ca2+ uptake. In addition, there is strong evidence that cytokinins stimulate an asymmetrical division in Funaria by increasing [Ca2+]i (Saunders and Hepler, 1981, 1982, 1983).
