The MAP kinase HwHog1 from the halophilic black yeast Hortaea werneckii: coping with stresses in solar salterns
BACKGROUND Hortaea werneckii is one of the most salt-tolerant species among microorganisms. It has been isolated from hypersaline waters of salterns as one of the predominant species of a group of halophilic and halotolerant melanized yeast-like fungi, arbitrarily named as "black yeasts". It has previously been shown that H. werneckii has distinct mechanisms of adaptation to high salinity envir...
متن کاملCellular responses to environmental salinity in the halophilic black yeast Hortaea werneckii.
The development of crop plants with increased salt tolerance necessitates the study of naturally salt-tolerant eukaryotic species. We studied the bio-synthesis of glycerol as a compatible solute in the halophilic eukaryotic microorganism, black yeast Hortaea werneckii. A restriction fragment-differential display technique was used to investigate the transcriptome of the organism. Eight differen...
متن کاملProduction and Characterization of Melanin Pigment from Halophilic Black Yeast Hortaea werneckii
Melanin is nearly a ubiquitous pigment synthesized by living organisms in the course of hydroxylation and polymerization of organic compounds. Melanins have immense application potentials in the field of agriculture, cosmetics and pharmaceutical industries (photoprotection and mosquitocidal activity isolated from Streptomycete). In this study, the halophilic black yeast, Hortaea werneckii produ...
متن کاملThe HOG pathway in the halophilic black yeast Hortaea werneckii: isolation of the HOG1 homolog gene and activation of HwHog1p.
The mitogen-activated protein kinase (MAPK) Hog1p plays an essential role in the yeast hyperosmotic response. A homolog of the HOG1 gene was isolated from the halophilic black yeast Hortaea werneckii encoding a putative 359 amino acid protein, HwHog1p, with high homology to Saccharomyces cerevisiae Hog1p and to other eukaryotic Hog1p homologs. HwHog1p contains a TGY motif within a protein kinas...
متن کاملExtremely halophilic bacteria in crystallizer ponds from solar salterns.
It is generally assumed that hypersaline environments with sodium chloride concentrations close to saturation are dominated by halophilic members of the domain Archaea, while Bacteria are not considered to be relevant in this kind of environment. Here, we report the high abundance and growth of a new group of hitherto-uncultured Bacteria in crystallizer ponds (salinity, from 30 to 37%) from mul...
