Involvement of ion channels and active transport in osmoregulation and signaling of higher plant cells

Trends Biochem Sci. 1989 May;14(5):187-92. doi: 10.1016/0968-0004(89)90272-7.


The transport of inorganic and organic ions across the plasma membrane and organelle membranes of higher plants by ion channels, electrogenic pumps and co-transporters is essential to vital processes such as osmoregulation, growth, development, signal transduction and the storage of solutes. Recent studies have led to the identification of specialized transport proteins in the plasma membrane and vacuolar membrane of higher plant cells. Here we have integrated the functional aspects of these membrane proteins into a model which proposes a novel basis for ion transport processes involved in the regulation of gas exchange in leaves.
