The active transport of ions in plant cells.
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 plantsread more

The utilization of inorganic and organic phosphorous compounds as nutrients by eukaryotic microalgae: a multidisciplinary perspective: part 1
TL;DR: This comprehensive literature review of the phosphorus nutrition and metabolism of eukaryotic microalgae deals sequentially with extracellular P-compounds available for algal utilization and growth and includes specific macroalgae in considering certain subtopics where such algae were better investigated and provided a good basis for comparison.

Cytoplasmic streaming in Chara: a cell model activated by ATP and inhibited by cytochalasin B
TL;DR: After vacuolar perfusion of Chara internode cells, the cytoplasm remaining in situ can be reactivated by ATP to give full rates of streaming and movement is interpreted in terms of actin filaments in the stationary cortex interacting with a myosin-like protein which is able to link to endoplasmic organelles.

The relationship between ATP and an electrogenic pump in the plasma membrane of Neurospora crassa
TL;DR: The data strongly suggest that an electrogenic ion pump in the plasma membrane of Neurospora is fueled by ATP; comparison of the measured membrane potentials with the energy available from hydrolysis of ATP indicates that two ions could be pumped for each molecule of ATP split.

Inorganic nutrient uptake and deficiency in algae.
TL;DR: An attempt is made to borrow information from the physiology of bacteria, fungi, and higher plants where they augment observations on algae in an attempt to find new insights into the metabolic roles of nutrients and the mechanisms of their assimilation.

From frog skin to sheep rumen: a survey of transport of salts and water across multicellular structures
TL;DR: In this paper, the authors consider the active transport of salts and water across some typical multicellular secretory tissues, and attempt in the process to discern what properties they have in common and in what respects they are specialized.

The nature of the coupling between light energy and active ion transport in nitella translucens.
TL;DR: It is suggested that K + uptake is supported by light energy through the utilization of ATP produced in photophosphorylation, but that the Cl − uptake is directly linked to the light-driven electron-transfer reactions associated with the evolution of O 2 in photosynthesis, and does not depend on photoph phosphorylation.

Ionic Relations of Nitella translucens
TL;DR: The ionic state of single internodal cells of a fresh water characean, Nitella translucens, has been studied, and the results suggest an active influx of potassium and an active efflux of sodium at the plasmalemma, and anactive influx of chloride, probably at the tonoplast.
