This project aims to increase our understanding of how plant cells regulate solute transport. Crop growth depends on water uptake and transport, and the rapid movement of water across plant cell membranes requires transporters such as aquaporins. Preliminary data indicates that a series of signals can switch aquaporins between functioning as highly selective water channels and salt transport channels. The project aims to reveal the molecular pathways that regulate water and salt co-transport, using genetics, molecular biology, and electrophysiology data to decipher how plants regulate and coordinate aquaporin solute transport during growth and in osmotic adjustment. The project has the potential to lead to improvements in crop-plant solute transport traits, enhanced agricultural productivity, and yield stability in saline and water limited environments.

该项目旨在加深我们对植物细胞如何调节溶质运输的理解。作物生长依赖于水的吸收和运输，水快速穿过植物细胞膜需要水通道蛋白等转运蛋白。初步数据表明，一系列信号可以使水通道蛋白在高度选择性的水通道和盐转运通道之间切换。该项目旨在揭示调节水和盐共同运输的分子途径，利用遗传学、分子生物学和电生理学数据来破译植物在生长和渗透调节过程中如何调节和协调水通道蛋白溶质运输。该项目有可能改善作物-植物溶质运输特性，提高农业生产力以及在盐和水有限环境中的产量稳定性。
