Abstract

The impact of aquaporin function on plant water balance is discussed. The significance of these proteins for root water uptake, water conductance in the xylem, including embolism refilling and the role of plant aquaporins in leaf physiology, is described. Emphasis is placed on certain aspects of water stress reactions and the correlation of aquaporins to abscisic acid as well as on the relation of water and CO2 permeability in leaves.

摘要

本文讨论了水通道蛋白功能对植物水分平衡的影响。描述了这些蛋白质在根系水分吸收、木质部水分传导（包括栓塞修复）中的重要性，以及植物水通道蛋白在叶片生理学中的作用。重点关注水分胁迫反应的某些方面、水通道蛋白与脱落酸的相关性，以及叶片中水分和二氧化碳渗透性的关系。
