TLDR
The present review indicates the existence of similar ion transports in higher plant cells, but it does not present a complete review of the experimental work on higher plants, and tries to assess progress towards understanding the mechanisms involved.
Abstract
In a recent review of the transport of salts and water across multicellular secretory tissues in animals (Keynes, 1969), a summary was given of the various types of active transport of ions necessary to explain the experimental observations in a very wide range of tissues, and five basic types of ion pump were discussed The question of whether plants and animals have any common mechanisms for the transport of salts and water was specifically excluded The original aim of the present review was to survey the types of ion pump found in plant cells and tissues, and to compare these with those found in animals Its aims narrowed very considerably in writing It now reviews ion transport processes in giant algal cells, and tries to assess progress towards understanding the mechanisms involved It indicates the existence of similar ion transports in higher plant cells, but it does not present a complete review of the experimental work on higher plants

Tetrathiafulvalene Radical Cation — A New Potent Inhibitor of Anion Transport in a Green Alga

TL;DR: In this paper, an inhibitory effect of potassium ferricyanide on the light-dependent active uptake of chloride anions into the alga Hydrodictyon reticulatum has been investigated.

Electrochemical State of Potassium and Sodium in Free Cells of Acer pseudoplatanus

TL;DR: The Na+ extrusion system of Acer cells ceased to be functional in Na+-depleted cells but recovered its function if the cells were placed in 10 mM NaCl, which suggests that the Extrusion system was induced by the level of internal Na+ ions.

Investigations on the growth and metabolism of cultured explants of Daucus carota : V. Effects of trace elements and growth factors on the solutes accumulated.

TL;DR: The evidence shows the range of factors that affect the accumulation of solutes in cells as they grow and is to be contrasted with conventional observations on mature cells held in steady states under conditions that preclude all growth and when only a single ionic species is followed over a very short interval of time.

Photoelectric effects in characean cells. I. The influence of light intensity.

TL;DR: From the influence of the light intensity on the frequency responses it was seen that the kinetic data depend on the intensity, and it could be demonstrated that a single cell is able of exhibiting all those different types of curve shapes reported in literature, if only one parameter, the lightintensity, is changed.

Chemiosmotic coupling in oxidative and photosynthetic phosphorylation

Peter Mitchell
- 01 Aug 1966 - 
TL;DR: The end result of the coupling between the flows through the o/r and h/d pathways in oxidative phosphorylation in mitochondria is that, for the equivalent of each pair of electrons traversing the respiratory chain, up to 3 anhydro-bond equivalents may normally traverse the h/D pathway from adenosine diphosphate plus inorganic phosphate (ADP +Pi) to water.

The Distinction by Means of Tracers Between Active Transport and Diffusion

TL;DR: It is shown that for a free ion diffusing through a membrane the ratio between the flux in one direction and the simultaneous flux in the opposite direction is independent of the structure of the membrane.

The concepts of membrane flow and membrane vesiculation as mechanisms for active transport and ion pumping.

TL;DR: The hypothesis that membrane flow may be an important part of a type of active transport mechanism carrying particles, including ions, along, within, into, and out of cells is introduced.
