Anhydrobiosis
way some applicants worry. A paper in Nature, Science or Cell is not essential to get an interview. Instead, our search committees look for evidence of success as a leader of a project in different environments (e.g. the PhD and postdoc labs) — a few fi rst-author publications that push a fi eld forward in journals of reasonable reputation and outstanding letters of recommendation from multiple...
متن کاملAnhydrobiosis in Pratylenchus penetrans.
Anhydrobiotic survival of Pratylenchus penetrans was compared in several soil moisture regimes. Bodies of anhydrobiotic nematodes were coiled. In slow-dried soils, Vineland silt loam (VSL) and Fox loamy sand (FLS), 70 and 58% of the total P. penetrans populations were anhydrobiotic when soil moistures reached ca. 3% and water potential 15 kPa or greater. Coiling began at a much lower water pote...
متن کاملAnhydrobiosis in yeast: activation effect.
Intracellular substances released into the medium during rehydration of dry yeast cells can significantly improve the quality of a synthetic medium. Acceleration of yeast growth in this medium and increased yield of biomass are observed simultaneously. The change in the molecular arrangement of intracellular membranes as a result of the strong dehydration of live organisms is a negative phenome...
متن کاملAnhydrobiosis: Drying Out with Sugar
The disaccharide trehalose is a major determinant of desiccation tolerance via unresolved mechanisms. A new study highlights a critical role for this chemical chaperone in energy-independent maintenance of protein homeostasis during extended periods of dehydration and relative metabolic inactivity.
متن کاملAnhydrobiosis without trehalose in bdelloid rotifers.
Eukaryotes able to withstand desiccation enter a state of suspended animation known as anhydrobiosis, which is thought to require accumulation of the non-reducing disaccharides trehalose (animals, fungi) and sucrose (plants), acting as water replacement molecules and vitrifying agents. We now show that clonal populations of bdelloid rotifers Philodina roseola and Adineta vaga exhibit excellent ...
