Calcium Signalling in Plants' Guard Cells

Caption

Left: A blue light pulse of 0.1 seconds triggers a calcium signal (red) in guard cells, which is followed by an anion current (black). Right: The influx of calcium into the cell promotes the release of further calcium from the endoplasmic reticulum (ER). The amplified calcium signalling activates anion channels and thus modulates stomatal dynamics.
