Abstract

This review examines the key aspects of ion exchange and diffusion in plant root cell walls and the implications of these processes for the uptake of mineral nutrients and water under both normal and adverse environmental conditions. The data available to date shows that the ion-exchange properties of plant root cell walls are influenced by the plant age and growth conditions, and also vary between species. The cell wall volume and its ability to swell, which regulate the hydraulic conductivity of the cell wall, are determined by the pH and ionic strength of the external solution. It is concluded that the analysis of physico-chemical properties of plant cell wall is an important step in the understanding of the complex processes of water and nutrient uptake.
