| 摘 要： | 钾是植物生长发育所必需的矿质营养元素之一。不同种类植物的钾营养效率存在差异，已有证据表明这种差异是受遗传基因控制的。植物细胞依靠细胞膜上的各种钾转运体和通道蛋白吸收和转运钾离子，这些膜蛋白的活性调控是植物钾营养效率调控的关键和基础。本文对植物钾营养高效性状分子遗传机制以及相关基因的分子功能和调控机制的研究进展进行了简要评述，并讨论了改善作物钾营养高效性状的可能途径。

| Abstract: | Potassium is an essential element for plant growth and development. Different plant species show various K^＋ utilization efficiency controlled by genes. Increasing evidence has confirmed that plant K^＋ transporters, K^＋ channels and related regulatory proteins play crucial roles in controlling plant K^＋ efficiency. In this review, we introduce the advances in investigation of plant K^＋ nutrition and summarize the molecular mechanisms of related genes. Approaches to enhancing plant K^＋ efficiency are also discussed. |
