A comparative study was conducted concerning the effect of temperature stress on the lipid composition of representatives of the subkingdomsEomycota andNeomycota. Changes in the composition of lipid acyl chains (such as saturation and desaturation, isomerization, and changes in the length of fatty acid carbon chains), in the phospholipid composition, and in the contents of sterols and other neutral lipids were revealed. Hyperthermia resulted in (i) an increase in the phosphatidylcholine level… Expand

Effects of exogenous lipids and cold acclimation on lycopene production and fatty acid composition in Blakeslea trispora
TLDR
Lycopene production was increased with the improved desaturation degree of intracellular lipids, which may be attributed to the enhancement of storage capacity for lycopene in storage lipid, thus reducing the feedback regulation of free Lycopene. Expand
Adaptation of Flammulina velutipes to Hypothermia in Natural Environments: The Role of Lipids and Carbohydrates
TLDR
Under hypothermic conditions, glycerol, known to have antifreeze properties, accumulated in the cell cytosol along with arabitol and trehalose, and the significance of this biochemical strategy in the resistance of the fungus to temperatures below zero is discussed. Expand

TLDR
An ecologically friendly method for extracting lipids from fungal mycelia, utilizing supercritical technologies, has been used and a correlation between the lipid content in the spore inoculum and the maximal lipidcontent in biomass has been discovered. Expand
Triacylglyceride composition and fatty acyl saturation profile of a psychrophilic and psychrotolerant fungal species grown at different temperatures.

Effect of heat stress on production and in-vitro antioxidant activity of polysaccharides in Ganoderma lucidum
TLDR
Results of in-vitro antioxidant activity assay revealed that 42 °C HS significantly improved the antioxidant activities of polysaccharides at the concentration of 2 mg/mL, which provides a promising strategy to improve the production of G. lucidum fruiting body poly Saccharides. Expand
The Perigord black truffle responds to cold temperature with an extensive reprogramming of its transcriptional activity.
TLDR
It is hypothesized that these differentially expressed genes may help the truffle to adapt to low temperatures and/or perceive environmental signals that regulate the fructification. Expand
De novo transcriptome sequencing and comprehensive analysis of the heat stress response genes in the basidiomycetes fungus Ganoderma lucidum.
TLDR
This comprehensive transcriptome analysis will provide enlarged resource for further investigation into the molecular mechanisms of basidiomycete under HS condition, suggesting that a series of metabolic pathways in Ganoderma lucidum are activated by HS and the response mechanism involves a complex molecular network which needs further study.

Experimental Evolution of a Facultative Thermophile from a Mesophilic Ancestor
TLDR
The use of a recently described long-term culture apparatus called the Evolugator for the generation of a thermophilic descendant from a mesophilic ancestor and demonstrates the potential to accelerate the selection for complex traits by experimental evolution and significantly decrease development time for new industrial strains.

EFFECT OF LOW TEMPERATURE SHOCK TREATMENT ON SPOROPHORE INITIATION, LIPID PROFILE AND NUTRIENT TRANSPORT IN LENTINULA EDODES
TLDR
Following the cold shock treatment, there was an increase in the degree of unsaturation of the polar lipids of the mycelium caused by the variation in the proportion of C18:2 and C16:0. Expand

TLDR
The regulatory mechanism of a key enzyme, palmitoyl-CoA desaturase, involved in the adaptation to temperature shift was investigated by labeling Tetrahymena pyriformis cells with [14C]palmitic acid, and data would provide evidence for temperature-triggered increase of palmitosine level. Expand
Mechanism of thermal adaptation of membrane lipids in Tetrahymena pyriformis NT-1. Possible evidence for temperature-mediated induction of palmitoyl-CoA desaturase.
TLDR
The regulatory mechanism of a key enzyme, palmitoyl-CoA desaturase, involved in the adaptation to temperature shift was investigated by labeling Tetrahymena pyriformis cells with [ 14 C]palmitic acid and the rate of conversion was shown to be dependent on incubation temperature. Expand

TLDR
The major factor affecting the fluidity of membrane lipids in eukaryotes, apart from the presence of cholesterol, is the degree of unsaturation of their fatty acid chains. Expand
Regulatory mechanism of desaturation activity in cold acclimation of Tetrahymena pyriformis with special reference to quick cryoadaptation
TLDR
Investigation of changes in palmitate desaturation involving the quick cryoadaptation under inhibition of protein synthesis with actinomycin D or puromycin in Tetrahymena provided evidence which supports at least in part the hypothesis of desaturase induction, and led to postulate that, once synthesized, palmitoyl-CoA desatur enzyme would be controlled by membrane fluidity of microsomes in Tetrahymena cells.

Membrane lipid composition and cellular function.
TLDR
Membrane fatty acid composition, phospholipid composition, and cholesterol content can be modified in many different kinds of intact mammalian cells, and many of the functional responses probably are caused directly by the membrane lipid structural changes, which affect either bulk lipid fluidity or specific lipid domains.
