Molecular responses to dehydration and desiccation in desiccation-tolerant angiosperm plants [PDF]

Journal of Experimental Botany, 2018
Due to the ability to tolerate extreme dehydration, desiccation-tolerant plants have been widely investigated to find potential approaches for improving water use efficiency or developing new crop varieties. The studies of desiccation-tolerant plants have identified sugar accumulation, specific protein synthesis, cell structure changes, and increased ...

Selection Mapping Identifies Loci Underpinning Autumn Dormancy in Alfalfa (Medicago sativa). [PDF]

, 2018
Autumn dormancy in alfalfa (Medicago sativa) is associated with agronomically important traits including regrowth rate, maturity, and winter survival. Historical recurrent selection experiments have been able to manipulate the dormancy response.

Temporal profiling of the heat-stable proteome during late maturation of Medicago truncatula seeds identifies a restricted subset of late embryogenesis abundant proteins associated with longevity [PDF]

, 2012
Developing seeds accumulate late embryogenesis abundant (LEA) proteins, a family of intrinsically disordered and hydrophilic proteins that confer cellular protection upon stress. Many different LEA proteins exist in seeds, but their relative contribution

Mechanisms of Desiccation Tolerance: Themes and Variations in Brine Shrimp, Roundworms, and Tardigrades

Frontiers in Physiology, 2020
Water is critical for the survival of most cells and organisms. Remarkably, a small number of multicellular animals are able to survive nearly complete drying.

Desiccation tolerance of prokaryotes

Microbiological Reviews, 1994
The removal of cell-bound water through air drying and the addition of water to air-dried cells are forces that have played a pivotal role in the evolution of the prokaryotes. In bacterial cells that have been subjected to air drying, the evaporation of free cytoplasmic water (Vf) can be instantaneous, and an equilibrium between cell-bound water (Vb ...

Pre‐treatment with D942, a furancarboxylic acid derivative, increases desiccation tolerance in an anhydrobiotic tardigrade Hypsibius exemplaris

FEBS Open Bio, 2020
The tardigrade Hypsibius exemplaris can undergo anhydrobiosis. Several chemicals that inhibit successful anhydrobiosis in H. exemplaris have been identified, and these chemicals inhibit the activity of signaling molecules.

Physiological, morphological and ecological traits drive desiccation resistance in north temperate dung beetles

BMC Zoology, 2021
Background Increasing temperatures and changes in precipitation patterns threaten the existence of many organisms. It is therefore informative to identify the functional traits that underlie differences in desiccation resistance to understand the ...

The response of perennial and temporary headwater stream invertebrate communities to hydrological extremes [PDF]

, 2009
The headwaters of karst rivers experience considerable hydrological variability, including spates and streambed drying. Extreme summer flooding on the River Lathkill (Derbyshire, UK) provided the opportunity to examine the invertebrate community response

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

3D Multi-isotope Imaging Mass Spectrometry Reveals Penetration of \(^{18}O\)-Trehalose in Mouse Sperm Nucleus [PDF]

, 2012
The prevalence of genetically engineered mice in medical research has led to ever increasing storage costs. Trehalose has a significant beneficial effect in preserving the developmental potential of mouse sperm following partial desiccation and storage ...
