Abstract excerpt
Cytosolic free calcium ([Ca2+]cyt) is a ubiquitous signalling component in plant cells. Numerous stimuli trigger sustained or transient elevations of [Ca2+]cyt that evoke downstream stimulus-specific responses. Generation of [Ca2+]cyt signals is effected through stimulus-induced opening of Ca2+-permeable ion channels that catalyse a flux of Ca2+ into the cytosol from extracellular or intracellular stores. Many...
