Abstract

This review introduces the pressure probe technique that was originally designed to detect the turgor of a giant algal cell, then adapted to measure the turgor and other water-relations parameters of higher plants, and now has developed into a diverse tool on researches of plant physiology and eco-physiology. This technique can be used to measure in situ the permeability of cell membranes to water and solutes at the resolution of single cells, and hence is a useful tool to study function and regulation of water channels (aquaporins) of intact plant cells. The recently developed xylem-pressure probe technique is the only way to directly measure the negative pressure in xylem conduits. In this review we introduce the basic principles and the theoretical backgrounds underlying the pressure probe. Finally some important achievements and applications of the pressure probe in studies of plant water relations are reviewed and discussed.

[压力探针技术在植物水分关系研究中的应用]。
本文介绍了压力探针技术,该技术最初用于检测巨藻细胞的膨胀,后来被用于测量高等植物的膨胀和其他水关系参数,现在已发展成为植物生理学和生态生理学研究的多种工具。该技术可以在单细胞分辨率下原位测量细胞膜对水和溶质的渗透性,因此是研究完整植物细胞中水通道(水通道蛋白)功能和调控的有用工具。近年来发展起来的木质部压力探针技术是直接测量木质部导管负压的唯一方法。本文介绍了压力探头的基本原理和理论背景。最后对压力探针在植物水分关系研究中的一些重要成果和应用进行了综述和讨论。
