smirnovia iranica (sabeti) synonym: smirnovia turkestana (bunge) is a deciduous perennial bushy species of the fabaceae (papilionaceae) family. the species grow on sand dunes of desert areas, having a deep vertical root and very long horizontal or lateral roots. they have an important role in natural vegetation of desert and sand dune stabilization. limited growing areas, grazing due to good pa...

In an effort to define the nature of desiccation tolerance, a comparison of the water sorption characteristics was made between tissues that were resistant and tissues that were sensitive to desiccation. Water sorption isotherms were constructed for germinated and ungerminated soybean axes and also for fronds of several species of Polypodium with varying tolerance to dehydration. The strength...

We report a study on the presence of the disaccharide trehalose in three desiccation tolerant tardigrades. This sugar has long been suggested to play a protective role in desiccation tolerant animals. Trehalose was found in all species, with increased levels in dehydrated specimens of Macrobiotus islandicus, and possibly also in Macrobiotus krynauwi, both belonging to the family Macrobiotidae. ...

Desiccation and high salinity are two abiotic stressors that related in terms of their effect on water homeostasis within cells. The success certain aeroterrestrial microalgae is influenced by ability to cope with desiccation, some cases, salinity. the Stichococcus clade ubiquitous terrestrial habitats known withstand desiccation stress accumulating secondary metabolites. Nevertheless, it remai...

Drying to equilibrium with the air is lethal to most species of animals and plants, making drought (i.e., low external water potential) a central problem for terrestrial life and a major cause of agronomic failure and human famine. Surprisingly, a wide taxonomic variety of animals, microbes, and plants do tolerate complete desiccation, defined as water content below 0.1 g H(2)O g(-1) dry mass. ...

A series of experiments were conducted to determine the effectiveness of rapid desiccation with dry heat at one or two points in the slaughter process to reduce bacterial contamination on beef carcass surfaces. In the first set of experiments, several combinations of desiccation and water washes were examined. Beef surfaces were inoculated with bovine feces and water washed (IW; 125 psi, 15 s, ...
