Uridine 5'-hexadecylphosphate (UMPC16) inhibited the growth of Saccharomyces cerevisiae under a hypersaline stress condition with Na+ more strongly than the calcineurin inhibitor cyclosporine A (CsA). Additional Ca2+ supplementation similarly suppressed the inhibitory activities of UMPC16 and CsA on yeast cell growth in a medium with Na+. UMPC16, but not CsA, accelerated mitochondrial reactive oxygen species (ROS) generation in combination with Na+, suggesting its inhibition of a Ca2… 
Mutations in the RAM network confer resistance to the thiol oxidant 4,4′-dipyridyl disulfide
TLDR
The broad resistance toward oxidants (DPS, diamide and H2O2) of the Δcts1 strain links cell wall function to the resistance to oxidative stress and suggests the existence of targets that are common for these oxidants.
Overview of Oxidative Stress Response Genes in Selected Halophilic Fungi
TLDR
W. ichthyophaga can survive salinities detrimental to most other organisms with only a moderate number of oxidative stress response genes, and this observation supports the hypothetical link between the antioxidant capacity of cells and their halotolerance.
A high-throughput RNA-Seq approach to elucidate the transcriptional response of Piriformospora indica to high salt stress
TLDR
This study on the salt-responsive DEGs established a foundation for the elucidation of molecular mechanisms related to P. indica stress adaptation and a future reference for comparative functional genomics studies of biotechnologically important fungal species.
Bacterial and fungal communities are differentially modified by melatonin in agricultural soils under abiotic stress
TLDR
The analysis indicated that the microbial response to melatonin is governed by the type of soil and history, and the effects of melatonin on soil microbes needs to be regarded in potential future agricultural applications.

The analysis indicated that the microbial response to melatonin is governed by the type of soil and history, and the effects of melatonin on soil microbes need to be regarded in potential future agricultural applications.

Farnesol-Induced Generation of Reactive Oxygen Species via Indirect Inhibition of the Mitochondrial Electron Transport Chain in the Yeast Saccharomyces cerevisiae
TLDR
The present study supports the idea that FOH inhibits the ability of the electron transport chain to accelerate ROS production via interference with a phosphatidylinositol type of signal.
Protein phosphatase type 2B (calcineurin)‐mediated, FK506‐sensitive regulation of intracellular ions in yeast is an important determinant for adaptation to high salt stress conditions.
TLDR
The growth behaviour and intracellular Na+ and K+ of wild type cells in high NaCl medium became very similar to those of the PP2B‐deficient mutant in a manner dependent on the presence of the FK506 binding protein.
Calcineurin inhibits VCX1-dependent H+/Ca2+ exchange and induces Ca2+ ATPases in Saccharomyces cerevisiae
TLDR
It is proposed that elevated cytosolic free Ca2+ concentrations, calmodulin, and calcineurin regulate at least four ion transporters in S. cerevisiae in response to several environmental conditions.
An Osmotically Induced Cytosolic Ca2+ Transient Activates Calcineurin Signaling to Mediate Ion Homeostasis and Salt Tolerance of Saccharomyces cerevisiae *
TLDR
NaCl-induced ENA1expression was inhibited by EGTA, cch1Δ mutation, and FK506, indicating that the [Ca2+] cyt transient activates calcineurin signaling to mediate ion homeostasis and salt tolerance.
The Yeast HAL2 Nucleotidase Is an in Vivo Target of Salt Toxicity*
TLDR
The results suggest that the cation sensitivity of the HAL2 nucleotidase is an important determinant of the inhibition of yeast growth by sodium and lithium salts.
Ion homeostasis in Saccharomyces cerevisiae under NaCl stress
TLDR
The present review discusses the systems, which are most critical in determining K+/Na+ homeostasis, emphasizing recent progress in the authors' understanding of how cation transport systems are regulated to maintain a functional intracellular ion environment.
An essential role of the yeast pheromone-induced Ca2+ signal is to activate calcineurin.
TLDR
Calcineurin is essential in yeast cells during prolonged exposure to pheromone and especially under conditions of pHERomone-induced growth arrest, and observations suggest that the essential function of calcineur in the phersomone response may be distinct from its modulation of intracellular Ca2+ levels.
