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

Light Sensitivity of 22Na, 86Rb, and 42K Absorption by Different Tissues of Bean Leaves

TL;DR: Autoradiographs of (22)Na-loaded bean (Phaseolus vulgaris L. cv. ;Brittle Wax') leaf slices showed that most of the tracer was concentrated in vascular tissue, while Rubidium-86 was uniformly distributed in slices that had been incubated in darkness.

The role of electrogenic pump in Chara corallina

TL;DR: The conductance,G, and the electromotive force,E, of theChara membrane were determined accurately by using the current-clamp technique and may help in accelerating the inactivation of the excitatory mechanism.

Ionic channels, ion transport and plant cell membranes: Potential applications of the patch-clamp technique

TL;DR: An important step forward would be the application of patch-clamp techniques for the direct demonstration of a channel mechanism and the subsequent elucidation of their role.

Investigations on the growth and metabolism of cultured explants of Daucus carota

TL;DR: In this article, the authors investigated the effects of the component parts of the growth promoting systems, separately and in combination, with respect to their interactions with Mo, with Fe and also with these trace elements in combination.

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.
