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

Effect of salinity on the free amino acids pool of the red alga Porphyridiumpurpureum (= P. cruentum)

TL;DR: The results indicate that participation of the amino acids in the intracellular fluid osmoregulation might rely on mechanisms of very general occurrence also present in representatives of the plant kingdom.

Respiration and photosynthesis as alternative energy sources for chloride uptake by Tradescantia albiflora leaf cells

TL;DR: The results suggest that Cl− uptake under aerobic conditions is powered by a cytoplasmic pool of ATP, which can be explained as either non-cyclic photophosphorylation or oxidative phosphorylation, with respiration being driven by photosynthetically produced O2.

Ouabain-insensitive K influx in Hydrodictyon africanum

TL;DR: The low ouabain sensitivity of the total K influx seems to be related to a smaller than usual activity of the component of K influx which is linked to Na efflux, and also to a small sensitivity of this component to inhibition by ou abain.

Net H(+) influx inNitella clavata.

TL;DR: Net H+ influx measurements on the giant internodal cells of the alga, Nitella clavata, have been made and results support the hypothesis that theNitella membrane is very permeable to H+.

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.
