Abstract
Basic knowledge on plant membranes has been greatly indebted to internodal
cells of charophytes, which are aquatic cryptogams mostly growing in fresh
water and some in brackish water. The huge size of the internodal cell enables
us to study water and ion transport in a single cell. Furthermore, the cell
can be subjected to various kinds of cell operations such as preparation of
cells having abnormal osmotic pressures, effusion of the steaming endoplasm,
perfusion of the vacuole with artificial solutions, preparation of
tonoplast-free cells and plasma membrane-permeabilised cells. Taking advantage
of the large cell size and the cell operation techniques, various aspects of
characterisations of plant membranes (plasma membrane, tonoplast,
endomembranes) have been achieved using characean cells. The present article
intends to depict unique contributions of characean cells to membrane
physiology and biophysics in the last century, focusing on several topics and
with historical perspectives.
