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.

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 ...

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.

Tolerance to environmental desiccation in moss sperm

New Phytologist, 2012
• Sexual reproduction in mosses requires that sperm be released freely into the environment before finding and fertilizing a receptive female. After release from the male plant, moss sperm may experience a range of abiotic stresses; however, few data are available examining stress tolerance of moss sperm and whether there is genetic variation for ...

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.

The involvement of ubiquitin in vegetative desiccation tolerance

Plant Molecular Biology, 1999
We have isolated a polyubiquitin cDNA from the modified desiccation-tolerant grass Sporobolus stapfianus. This cDNA, along with a commercially available polyclonal ubiquitin antibody, was used to characterize desiccation/rehydrated-associated changes in ubiquitin-mediated protein degradation in S.

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

Desiccation tolerant plants in South America

Oecologia, 1987
Numerous Velloziaceae species concentrated in Minas Gerais, Brazil, constitute most of the desiccation tolerant flora of S. America. In the grasses, two Microchloa spp and Tripogon spicatus are desiccation tolerant. Though widespread, they are low growing and appear unimportant. With the exception of Anemia, desiccation tolerant ferns in dry land areas
