Abstract

The central role of Ca^2+^ signalling in plants is now well established. Much of our recent research has been based on the premise that the direct demonstration of signal‐response coupling via Ca^2+^ requires the imaging or measurement of cytosolic free Ca^2+^ in living cells. Methods (confocal microscopy, fluorescence ratio imaging and photon counting imaging) which we use for imaging Ca^2+^ with fluorescent dyes or recombinant aequorin, are described. Approaches for using dyes are now routine for many plant cells. However, the imaging Ca^2+^ in whole tissues of plants genetically transformed with the aequorin gene is a very new development. We predict that this method, first employed in our laboratory, will bring about a revolution in our understanding of Ca^2+^ signalling at the multicellular level.

An increasing number of studies indicate that changes in cytosolic free Ca2+ ([Ca"],) mediate specific types of signal transduction in plant cells. Modulation of [Ca2+], is likely to be achieved through changes in the activity of Ca2+ channels, which catalyse passive influx of Ca2+ to the cytosol fr
