Considerable advances have been made, both in the technologies available to study changes in intracellular cytosolic free Ca ([Ca ] ), and in our understanding of Ca signalling cascades in plant cells, but how specificity can be generated from such a ubiquitous component as Ca is questionable. Recently the concept of 'Ca signatures' has been formulated; tight control of the temporal and spatial characteristics of alterations in [Ca ] signals is thought to be responsible, at least in part, for the specificity of the response. However, the way in which Ca signatures are decoded, which depends on the nature and location of the targets of the Ca signals, has received little attention. Read More
