“…Anhydrobiotic organisms possess the ability to survive desiccation in nature to water contents around 0.02 -0.05 g H 2 O g -1 dry mass and enter into a state that approaches suspended animation (Clegg, 1973;Madin, 1974, 1975;Hinton, 1968). Desiccation tolerance has also been observed in some flowering plants, algae, fungi, bacteria, and most seeds of higher plants are desiccation tolerant (Billi and Potts, 2002;Crowe et al, 1992;Hoekstra et al, 2001;Potts, 1999). In the study…”

Graphical AbstractHighlights: ØThe Late Embryogenesis Abundant protein AfLEA1.3 from Artemia franciscana accumulates in the mitochondrion of Drosophila Kc167 cells. Ø AfLEA1.3 improves mitochondrial functions in presence of high sodium chloride concentrations. Ø AfLEA1.3 reduces mitochondrial damage during freeze-thawing. Ø AfLEA1.3 increases cellular tolerance to osmotic stress. Ø AfLEA1.3 increases cellular tolerance to convective drying.

“…Typically, the external environment of cells under matric stress is the ambient atmosphere, while that of cells under osmotic stress is an aqueous solution. The water activity of an aqueous solution is affected by the concentration of solutes in solution, while that of air is affected by the relative humidity of the immediate environment (Billi and Potts, 2002). If there is a considerable difference in water activity between the cell and its immediate environment, the efflux of water out of the cell will happen at a rapid rate.…”

“…The capacity for prokaryotes to survive desiccation stress requires a variety of physiological responses ranging from cellular protection to repair of desiccationinduced damage (Billi and Potts, 2002). These responses include the production of exopolysaccharides (EPS), the induction of stress response proteins which protect cell membranes and repair DNA damage, and the accumulation of compatible solutes (Cytryn et al, 2007;Vanderlinde et al, 2010).…”

“…This phenomenon is termed anhydrobiosis (Billi and Potts, 2002;Clegg, 2001;Crowe, 2002;Crowe et al, 1998). The terrestrial cyanobacterium Nostoc commune can remain viable for over 100 years in a desiccated state (Cameron, 1962;Lipman, 1941).…”

The terrestrial cyanobacterium Nostoc commune forms macroscopic colonies in its natural habitats, and these colonies consist of both cellular filaments and massive extracellular matrixes. In this study, the biochemical features of the extracellular matrix components were investigated. Naturally growing N. commune was tolerant to desiccation, and produced massive extracellular polysaccharides that contained both neutral sugars and glucuronic acid as constituent monosaccharides. The extracellular polysaccharide contents and desiccation tolerance were compared in laboratory culture strains of Nostoc species. The laboratory culture of N. commune strain KU002 was sensitive to desiccation and produced smaller amounts of extracellular polysaccharides, unlike the field-isolated naturally growing colonies. Nostoc punctiforme strain M-15, which is genetically closed to N. commune, was able to tolerate desiccation, although the other Nostoc strains were desiccation-sensitive. A laboratory culture strain of the aquatic cyanobacterium Nostoc sphaericum produced massive extracellular polysaccharides but was sensitive to desiccation, suggesting that extracellular matrix production is not enough to make this strain tolerant to desiccation. WspA (water stress protein) and SodF (superoxide dismutase) were found to be characteristic protein components of the extracellular matrix of N. commune. Because the WspA proteins were heterogeneous, the wspA genes were highly diverse among the different genotypes of N. commune, although the sodF gene was rather conservative. The heterogeneity of the WspA proteins suggests their complex roles in the environmental adaptation mechanism in N. commune.
