	<span style=\"font-size:14px;\">低温冷害是最为严重的自然灾害之一。低温冷害抑制植物的生长发育，全世界范围内每年因0℃以上的低温冷害造成的作物经济损失达数千亿元。因此研究植物的低温胁迫适应机理，提高其低温抗性不仅具有十分重要的科学意义，而且有着更为重要的现实价值。Ca<sup>2+</sup>作为重要的第二信使不仅参与调控植物的生长发育过程，还参与调控各种生物与非生物胁迫应答。本文重点论述了Ca<sup>2+</sup>调控植物低温胁迫应答的分子机制。<br />
Cold stress presents one of the major limitations for plant growth, development and yield world-wide, as well as distribution, especially in areas of north and high-latitude regions. Worldwide, the annual crop economic losses due to the low temperature above 0？C is amount to hundreds billions of yuan. So an investigation of responses mechanism of cold stress in plant and improvement of its resistance has significant important value. Ca<sup>2+</sup> acts as the second messenger coupling of extracellular signals and intracellular physiological response. It plays an important role in mediating plant growth and development, as well as involved in the regulation of various abiotic stresses. The review discusses the molecular mechanism of Ca<sup>2+</sup> regulating cold stress in plant.</span><span style=\"font-size:14px;\"></span>
