Repair-Based Mechanism of Desiccation Tolerance
Desiccation tolerance of the moss Tortula ruralis is characterized by a desiccation-induced change in gene expression that becomes evident upon rehydration. As reported earlier, this change in gene expression is apparently brought about by a change in the control of translation and does not include a major shift in mRNA abundance. A full qualitative and quantitative analysis of the alteration i...
متن کاملCephalobus litoralis: Biology and Tolerance to Desiccation.
Cephalobus litoralis (Akhtar, 1962) Andrássy, 1984 reproduced parthenogenetically and completed its life cycle in 72-90 hours. Each female deposited 200-300 eggs. The nematodes showed synchronized movements in the rhythms of the anterior parts of the body. The nematodes were coiled when dried in culture medium or in slowly evaporating water droplets on the tops of culture plates, but in pellets...
متن کاملEngineering desiccation tolerance in Escherichia coli.
Recombinant sucrose-6-phosphate synthase (SpsA) was synthesized in Escherichia coli BL21DE3 by using the spsA gene of the cyanobacterium Synechocystis sp. strain PCC 6803. Transformants exhibited a 10,000-fold increase in survival compared to wild-type cells following either freeze-drying, air drying, or desiccation over phosphorus pentoxide. The phase transition temperatures and vibration freq...
متن کاملDesiccation tolerance in the moss Polytrichum formosum: physiological and fine-structural changes during desiccation and recovery.
BACKGROUND AND AIMS This study explores basic physiological features and time relations of recovery of photosynthetic activity and CO(2) uptake following rehydration of a desiccation-tolerant moss in relation to the full temporal sequence of cytological changes associated with recovery to the normal hydrated state. It seeks reconciliation of the apparently conflicting published physiological an...
متن کاملGenetic analysis of desiccation tolerance in Sachharomyces cerevisiae.
Desiccation tolerance, the ability to survive nearly total dehydration, is a rare strategy for survival and reproduction observed in all taxa. However, the mechanism and regulation of this phenomenon are poorly understood. Correlations between desiccation tolerance and potential effectors have been reported in many species, but their physiological significance has not been established in vivo. ...
