TLDR
Histochemical assays were carried out on mycelium of Dendryphiella salina cultured in media containing either potassium chloride or sea water, finding that adenosine triphosphatase showed enhanced activity and potassium or sodium ions were added to the assays of material from the potassium chloride cultures.Abstract:
Histochemical assays were carried out on mycelium of Dendryphiella salina cultured in media containing either potassium chloride or sea water. Adenosine triphosphatase showed enhanced activity in mycelium from sea-water cultures. The addition of potassium or sodium ions to the assays of material from the potassium chloride cultures also increased this activity. There was less activity in young hyphal tips compared with older areas of the mycelium. These observations help to explain the compartmentation of potassium fluxes in the mycelium of Dendryphiella salina .read more

Models of cell differentiation in conidial fungi.
TL;DR: The presence of cross walls, or septa, in the filamentous phase of all conidial fungi is evidence for their relationship to higher fungal taxa and distinguishes them morphologically from the lower, aseptate hyphal forms such as the water molds and Zygomycetes.
Journal ArticleDOI
Fifty years of marine mycology
TL;DR: This review will highlight areas that warrant further investigation, including surveys for marine fungi in Africa, artic waters and south America, more detailed studies of their physiology and biochemistry, and to determine the marine origin of so called “marine derived” fungi.

Physiological heterogeneity within fungal mycelia: an important concept for a functional understanding of the ectomycorrhizal symbiosis.
John W.G. Cairney,R. M. Burke +1 more
TL;DR: It is suggested that it is only by considering the sum of the seemingly disparate physiological processes within the heterogeneous mycelium that mycorrhizal functioning can be fully understood.
Journal ArticleDOI
Transcellular ion currents and extension of Neurospora crassa hyphae.
TL;DR: The results suggest that Neurospora hyphae generate a proton current; protons are expelled distally by the H+-ATPase and return into the apical region by a number of pathways, including the symport of protons with phosphate and potassium ions.
Journal ArticleDOI
Transport of small lons and molecules through the plasma membrane of filamentous fungi.
TL;DR: Concentrating on filamentous fungi, emphasis is placed on relating results from biophysical chemistry, membrane transport, fungal physiology, and fungal ecology to delineate the lively network of membrane transport systems rather than listing the properties of single transport systems.

Measurement of membrane potentials in Neurospora.
TL;DR: Microelectrodes were used to record intracellularly from the filamentous fungus Neurospora crassa, and the potentials were potassium-sensitive, and depended upon the distance of the cells from the growing margin of the colony.

Correlated changes in membrane potential and ATP concentrations in Neurospora.
TL;DR: The fungus Neurospora is examined, in which the relationship between metabolic and electrical events seems particularly close, and the energy for this particular mode of ion transport is provided by ATP or comes more directly from electron transfer, as suggested by Conway's “redox pump” hypothesis.

The effect of cations on the growth of fungi
E. B. G. Jones,D. H. Jennings +1 more
TL;DR: In this article, Dendryphiella salina Pugh has been grown in glucose-tryptone media differing in their ionic composition and the results are interpreted in terms of the permeability of the hyphae to potassium.
