Abstract :
Calcium (Ca++ ) is an essential element required for growth and development of plants both
under stressed and non-stressed situations. It not only maintains the integrity of cell wall and
membrane, but also serves as a second messenger in many developmental and physiological
processes thereby inducing Ca 2+ influx into cytosol, which decodes into downstream responses like
defense against various environmental cues. Therefore, maintenance of intracellular Ca2+
homeostasis is essential for Ca 2+ signalling. In this review, the current knowledge about the Ca2+
uptake, transport and signal transduction in different physiological aspects with respect to plant
nutrient status will be discussed.
