The Role of Calcium in the Regulation of Plant Cellular Metabolism
Living systems have established several mechanisms by which they transduce extracellular signals into an intracellular language which can be understood by the biochemical and biophysical machinery of the cell. One such mechanism was discovered in animal cells almost 20 years ago by Robinson et al. (1971) and is called the second messenger principle with cyclic 3′,5′-adenosine monophosphate (cAMP) as the intracellular second messenger. With the discovery of calmodulin, a cellular Ca2+-binding protein, by Cheung (1980) it became apparent that Ca2+ fulfils all the criteria for being a second messenger in animals too. Recently Rasmussen (1981), in his monograph on Ca2+ and cAMP, has called them the “synarchic messengers”, with Ca2+ being even more important than cAMP (Rasmussen 1981). Recently, a book has been published describing the manifold physiological reactions which are mediated and regulated by calcium (Marmé 1985).
