摘　要：

钙离子在植物生长发育过程中具有重要作用。然而, 在喀斯特地区, 过多的钙离子能够抑制植物的生长、降低作物的产量、限制植物群落的分布, 给农业生产和生物多样性带来严重影响。近年来, 研究表明植物可通过多种方式抵抗钙离子胁迫。例如, 富集钙离子、排出钙离子、渗透调节、抗氧化酶调节、固醇甲基转移酶调节, 以及增强光合特性等。本文总结了钙离子胁迫对植物生长发育的影响和植物抵抗钙离子胁迫的分子机制等方面的最新研究进展。

Abstract:

Calcium ions play important roles during the process of plant growth and development. However, in karst area, excessive calcium ions could inhibit plant growth, decline crop yields, restrict plant communities, and bring serious impacts to agricultural production and biodiversity. In recent years, studies have shown that plants could resist calcium ions stress by various ways, e.g., enrichment of calcium ions, discharge of calcium ions, osmotic adjustment, antioxidant enzymes regulation, sterol methyl regulation, and enhancement of photosynthetic characteristics. In the present paper, the latest progress in the effect of calcium ions stress on plant growth and development was summarized, also the molecular mechanism that plants cope with calcium ions stress was elucidated.

Key words: plant; calcium ions stress; molecular mechanism; karst area
