Calcium is one of the essential elements in crops. It is widely present in roots, stems, leaves, flowers, fruits, and seeds, and is of great significance for the growth and development of crops. Calcium is a difficult element to redistribute, and its absorption and transport are subject to transpiration. Therefore, crops often experience physiological calcium deficiency, which weakens their stress resistance and reduces both yield and quality. Calcium in crops has dual functions. It not only participates in the formation of cell walls and membranes but also plays a role in responding to various environmental stimuli and internal growth and development signals as an intracellular second messenger. The absorption and transportation of calcium in cells are essential for maintaining intracellular calcium homeostasis and ensuring calcium signal transduction. In recent years, the function and application of calcium in crops have been extensively studied. In this study, we describe the distribution, absorption, transportation, and demand of calcium in crops, introduce the symptoms and causes of calcium deficiency in crops, review the nutritional structure functions of calcium, the second messenger function and the mechanism of calcium signal generation, transmission, and decoding, and summarize the role of calcium in crop growth and development, including its effects on yield, quality, and stress resistance. Meanwhile, the future research direction is proposed.
