生长激素生长素是植物细胞分裂和伸长的关键调节因子。由于植物缺乏肌肉，参与生长和运动的过程依赖于膨胀物的形成，从而依赖于溶质和水分的运输。现代电生理技术和分子遗传学为调节植物离子转运体对生长素的反应提供了新的线索。保卫细胞、下胚轴和胚芽鞘已成为研究生长素作用的主要模式系统。因此，这篇综述将集中在生长素在这些模型细胞类型中调节离子运输和细胞扩张的分子机制。
The growth hormone auxin is a key regulator of plant cell division and elongation. Since plants lack muscles, processes involved in growth and movements rely on turgor formation, and thus on the transport of solutes and water. Modern electrophysiological techniques and molecular genetics have shed new light on the regulation of plant ion transporters in response to auxin. Guard cells, hypocotyls and coleoptiles have advanced to major model systems in studying auxin action. This review will therefore focus on the molecular mechanism by which auxin modulates ion transport and cell expansion in these model cell types.
