Halotolerance is the adaptation of living (A living thing that has (or can develop) the ability to act or function independently) organisms to conditions of high (The relative proportion of salt in a solution) salinity.
Goals of studying halotolerance include increasing the agricultural productivity of lands affected by (Click link for more info and facts about soil salination) soil salination or where only saline water is available.
In addition, naturally halotolerant plants or microorganisms could be developed into useful (Click link for more info and facts about agricultural) agricultural crops or (A chemical phenomenon in which an organic molecule splits into simpler substances) fermentation organisms.

An understanding of halotolerance can be applicable to areas such as arid-zone agriculture, xeriscaping, aquaculture (of fish or algae), bioproduction of desirable compounds (such as phycobilins or carotenoids)using seawater to support growth, or remediation of salt-affected soils.
Conventionalagricultural species could be made more halotolerant by gene transfer from naturally halotolerant species (by conventional breeding or genetic engineering) or by applying treatments developed from anunderstanding of the mechanisms of halotolerance.
In addition, naturally halotolerant plants or microorganisms could be developedinto useful agricultural crops or fermentation organisms.

The other group included the less halotolerant strains, whose killer spectrum was less significant and either did not vary consistently with salt stress in the assay or decreased in its presence.
Although killer activity was found in yeasts belonging to the various classes of salt-stress tolerance, the percentage of strains showing this capacity increased significantly for the classes of higher halotolerance, while the percentage fraction of sensitive strains remained approximately constant.
This suggests a phenotypic relationship between high halotolerance and killer capacity manifestation in the presence of high salt concentrations, which is not a consequence of an increase in sensitivity to salt stress of the target strains.

 Ganster, Raymond W - Gene regulation by STD1: a tale of sugar and salt   (Site not responding. Last check: 2007-10-20)
Recent experiments implicate STD1 as a halotolerance factor since overexpression of STD1 dramatically improves growth in the presence of 1M NaCl.
The STD1-mediated growth advantage is specific to Na+ since increased STD1 does not confer a growth advantage in media containing 1 M KCl or 2 M sorbitol.
However the phenotype is complex since a 1 M NaCl growth advantage can also be observed in snf4 and snf5 strains as well as in std1, mth1 strains.

 Toth Plant Composition   (Site not responding. Last check: 2007-10-20)
There are few native grasses surviving in the area and most of these are halotolerant species that live on marginal areas where the introduced fodder species cannot tolerate the high salinity.
Among the commonest grass species, the order of halotolerance from the least to the most halotolerant species was Bothriochloa pertusa, Dicanthium caricosum, C. plectostachyon and C. nlemfuensis, Cynodon dactylon and Sporobolus pyramidatus.
Because of the ease of distinguishing the vegetation categories and the straightforwardness of the technique, which does not require any specific statistical preconditions, authors suggest the use of the occurrence of halotolerant plant species to judge the salinity status of the pasture.

The halotolerant dCA II also differs from typical halophilic proteins in retaining conformational stability and solubility in low to high salt concentrations.
The crucial role of electrostatic features in dCA II halotolerance is strongly supported by the ability to predict the unanticipated halotolerance of the murine CA XIV isozyme, which was confirmed biochemically.
A proposal for the functional significance of the halotolerance of CA XIV in the kidney is presented.

 Salinity Resistance
One of these lines was developed by habituating an Arabidopsis cell culture to grow in high salinity; wild type cultures do not survive in 70 mM NaCl, but forced growth in 50 mM NaCl for a year resulted in the establishment of a cell lines that now survives in >380 mM NaCl.
Consequently, characterization at the molecular and biophysical level of the important transport processes involved are difficult.
Although not good models of the intact root, to survive in high salinity all cells in a cell suspension culture must be expressing the necessary traits for halotolerance.

 FUNCTIONAL GENOMICS OF SALT TOLERANCE: THE YEAST OVEREXPRESSION APPROACH
In order to convert this knowledge into biotechnology, molecular biology is needed for the genetic modification of crop plants with halotolerance genes.
As complex biological phenomena have several limiting factors, a significant increase in salt tolerance will require the simultaneous gain of function of many halotolerance genes, a plausible but not trivial task.
It is ironic, however, that now that the tools for the generation of halotolerance crops start to be available, the radical ecologism recently imposed in Europe is preventing any further progress.

ABSTRACT: Studies were conducted to investigate the antibiotic resistance of freshwater, halophile and moderate halotolerant bacteria isolated from the nearshore part of Shira lake, which is affected by the activity of a health resort, and from the central part of the lake in the summer (June to August) of 1999.
It has been shown that the allochthonous microflora, which is brought into the lake with the resort effluent in mid-summer, is the anthropogenic factor contributing to an increase in the number of freshwater bacteria that feature multiple antibiotic resistance in the central part of the lake.
A mathematical model has been constructed to describe the dynamics of the antibiotic resistance of heterotrophic bacteria in the close-to-resort and the central parts of Shira lake under natural and anthropogenic impacts.

However, studies of halotolerant Dunaliella salina revealed a new class of proteins - halotolerant proteins - that can function in the entire range of salinity (0 to 4 M NaCl).
The crystal structure coupled with the series of site-directed mutants will aid in for the better understanding of: what is the unique nature of protein - solvent and weak interactions for these class of proteins?
What is the structural principle that confers the additional stability of halotolerance.
