Скачать или смотреть Salt stimulus causes a calcium wave in plants

University of Toronto biologists have found that plants react to salt, which is generally toxic to them, by causing a wave of calcium that ripples through each cell in the plant.

Here the calcium wave can be seen moving from the root to the left upwards through the plant to the right. This message causes the plants' cells to reconfigure themselves to process higher salt levels - essentially a warning transmission across the plant, from root to tip.
