Abstract

This review covers both methodical aspects and actual applications of ion imaging techniques in plant cell signal research. The methodological section explains the basic principles of fluorescence ion imaging, the impact of modern developments in fluorescence microscopy and introduces the most important fluorescence probes including aequorin and other photoproteins. It critically comments on loading strategies, intracellular compartmentation of probes and calibration procedures. The second part compiles actual researchareas where the application of ion imaging procedures has gained substantial achievements and helped to establish new concepts of calcium- and pH-dependent signalling. Examples comprise the hormonal control of stomatal movements, effects of gibberellic and abscisic acids in aleurone cells, elicitation of phytoalexin production, cytosolic pH and cell development, and signatures of Ca2+ as a universal signal in plant cells.
