Abstract

Plant hormones are a group of small signaling molecules produced by plants at very low concentrations that have the ability to move and function at distal sites. Hormone homeostasis is critical to balance plant growth and development and is regulated at multiple levels, including hormone biosynthesis, catabolism, perception, and transduction. In addition, plants move hormones over short and long distances to regulate various developmental processes and responses to environmental factors. Transporters coordinate these movements, resulting in hormone maxima, gradients, and cellular and subcellular sinks. Here, we summarize the current knowledge of most of the characterized plant hormone transporters with respect to biochemical, physiological, and developmental activities. We further discuss the subcellular localizations of transporters, their substrate specificities, and the need for multiple transporters for the same hormone in the context of plant growth and development.

植物激素运输和定位:运动中的信号分子。
植物激素是植物在极低浓度下产生的一组小信号分子,具有在远端移动和发挥作用的能力。激素稳态对平衡植物生长发育至关重要,受多种水平调控,包括激素的生物合成、分解代谢、感知和转导。此外,植物还通过短距离和长距离移动激素来调节各种发育过程和对环境因素的反应。转运蛋白协调这些运动,导致激素最大值、梯度以及细胞和亚细胞汇。在这里,我们总结了目前已知的大多数具有特征的植物激素转运体在生物化学、生理和发育活动方面的知识。我们进一步讨论了转运体的亚细胞定位,它们的底物特异性,以及在植物生长和发育的背景下,同一激素需要多个转运体。
