Technical Abstract: Versatility and specificity are usually mutually exclusive terms. However, as we discull calcium's role in plant nutrition, we are obliged to contrast the plethora of general 'housekeeping' functions of this element against the ability of calcium (CA2+)to impart signaling specificity during biological responses . Plants have evolved to rely on the unique properties of Ca2+ for a range of structural, enzymatic and signaling functions. In this brief udpate, I will attempt to touch upon the various roles of Ca2+ in plant nutrition, growth and development.
