Plants can measure the intensity of salt stress

Researchers at the University of Münster have identified a specific group of cells in plant roots that react to salt stress, forming a 'sodium-sensing niche' and triggering a calcium signal. This signal is controlled by a calcium-binding protein (CBL8) that helps pump out salt from the plant under severe stress conditions.
