Cloning and characterization of the Halobacillus trueperi betH gene, encoding the transport system for the compatible solute glycine betaine.
Halobacillus trueperi accumulates glycine betaine under condition of high osmolarity. A fragment of the glycine betaine transporter betH gene was obtained from the genome of H. trueperi with degenerate primers. Through Southern blot hybridization and inverse PCR, a 5.1 kb EcoRI fragment containing the complete betH gene was identified and subsequently sequenced. The betH gene was predicted to e...
متن کاملCompatible Solute Engineering in Plants for Abiotic Stress Tolerance - Role of Glycine Betaine
Abiotic stresses collectively are responsible for crop losses worldwide. Among these, drought and salinity are the most destructive. Different strategies have been proposed for management of these stresses. Being a complex trait, conventional breeding approaches have resulted in less success. Biotechnology has emerged as an additional and novel tool for deciphering the mechanism behind these st...
متن کاملBetaine is the main compatible solute of halophilic eubacteria.
A number of moderately halophilic bacteria of diverse taxonomic groups have been studied to determine the intracellular concentrations of organic compounds at various salt concentrations. Betaine was accumulated in all of these organisms in proportion to the salinity of the medium, suggesting that this compound plays a major role in osmoregulation.
متن کاملGlycine betaine catabolism contributes to Pseudomonas syringae tolerance to hyperosmotic stress by relieving betaine-mediated suppression of compatible solute synthesis.
Many bacteria can accumulate glycine betaine for osmoprotection and catabolize it as a growth substrate, but how they regulate these opposing roles is poorly understood. In Pseudomonas syringae B728a, expression of the betaine catabolism genes was reduced by an osmotic upshift to an intermediate stress level, consistent with betaine accumulation, but was increased by an upshift to a high stress...
متن کاملthe search for the self in becketts theatre: waiting for godot and endgame
this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
