Desiccation Tolerance: Avoiding Cellular Damage During Drying and Rehydration

Annual Review of Plant Biology, 2020
Desiccation of plants is often lethal but is tolerated by the majority of seeds and by vegetative tissues of only a small number of land plants. Desiccation tolerance is an ancient trait, lost from vegetative tissues following the appearance of tracheids

Convergent evolution of desiccation tolerance in grasses

Nature Plants, 2023
Desiccation tolerance has evolved repeatedly in plants as an adaptation to survive extreme environments. Plants use similar biophysical and cellular mechanisms to survive life without water, but convergence at the molecular, gene, and regulatory levels remains to be tested. Here, we explore the evolutionary mechanisms underlying the recurrent evolution

Desiccation tolerance in Staphylococcus aureus

Archives of Microbiology, 2010
Staphylococcus aureus is a multidrug-resistant pathogen that not only causes a diverse array of human diseases, but also is able to survive in potentially dry and stressful environments, such as the human nose, on skin and on inanimate surfaces such as clothing and surfaces.

Desiccation Tolerance in Human Cells

Cryobiology, 2001
The ability to desiccate mammalian cells while maintaining a high degree of viability would have implications for many areas of biological science, including tissue engineering. Previously, we reported that introduction of the genes for trehalose biosynthesis allowed human cells in culture to be reversibly desiccated for up to 5 days.

Mechanisms of plant desiccation tolerance

Trends in Plant Science, 2001
Anhydrobiosis ("life without water") is the remarkable ability of certain organisms to survive almost total dehydration. It requires a coordinated series of events during dehydration that are associated with preventing oxidative damage and maintaining the native structure of macromolecules and membranes.

DNA and desiccation tolerance

Seed Science Research, 1994
AbstractThis article reviews mechanisms by which specialized cells of different life forms have overcome the lethal effects of dehydration and considers how the maintenance of genetic information is central to survival. As a dynamic and hydrated moleculein vivo, DNA can assume different conformational structures depending upon the water activity, the ...

Desiccation Tolerance in Mosses

1997
To gain a full understanding of stress-inducible processes in plants, especially at the cellular level, it is often of major benefit to develop simple model plants for study. This is especially true if one is interested in how plants tolerate extremely stressful conditions that impact directly on the protoplasm of individual cells, e.g., desiccation ...

Role of ABA and ABI3 in Desiccation Tolerance

Science, 2010
The hormone pathway that stabilizes seeds may have served more primitive seedless plants in supporting desiccation tolerance.

Exceptional desiccation tolerance of Acinetobacter radioresistens

Journal of Hospital Infection, 1998
The taxonomy of the genus Acinetobacter, which includes several important nosocomial pathogens, has been confused due to a lack of discriminatory phenotypic characteristics for identification. Molecular methods such as amplified ribosomal DNA restriction analysis (ARDRA) now enable the accurate identification of species.

Cryopreservation of Desiccation-Tolerant Seeds

2007
The cryopreservation of desiccation-tolerant seeds depends on two key steps: specimen dehydration in an environment that ensures the attainment of water contents below the high-moisture freezing limit; and transfer and maintenance at a subzero temperature that may be optimized in relation to the seed-lot moisture content and species. Temperatures about
