Plants as sessile organisms are constantly exposed to different stressors incidence: biotic and / or abiotic factors.
Consequently, the viability of plants depends on their ability to perceive the changes that occur in their natural
environment (either beneficial or harmful) and to appropriately respond physiologically, biochemically, and in terms of
their development, to overcome and to counter the possible destructive effects. Plasma membrane, as the main selective
barrier between the plant cell and the environment have different receptor proteins in its structure, to sense various
external stimuli and transduce them to downstream intra- and intercellular signalling networks. An universal signal
molecule is calcium and the calcium-sensing is of fundamental importance for extracellular calcium signalling and
calcium homeostasis. Calcium is an important second messenger in signal transduction pathways, mediating various
defence responses to the action under environmental stresses and in the regulation of many developmental processes in
plants, being one of the most studied second messengers both in plant and animal fields. This brief review summarizes
some results of recent research on the involvement of calcium in plant responses to stress factors action, addressing in
particular scientific and practical importance of such knowledge, in order to improve plant tolerance to stress factors.
