The ectD gene, which is involved in the synthesis of the compatible solute hydroxyectoine, is essential for thermoprotection of the halophilic bacterium Chromohalobacter salexigens
(American Society for Microbiology, 2006)
The halophilic bacterium Chromohalobacter salexigens synthesizes and accumulates compatible solutes in response to salt and temperature stress. 13C-nuclear magnetic resonance analysis of cells grown in minimal medium at ...

Sequence analysis of an archaeal virus isolated from a hypersaline lake in Inner Mongolia, China
(2007)
BACKGROUND: We are profoundly ignorant about the diversity of viruses that infect the domain Archaea. Less than 100 have been identified and described and very few of these have had their genomic sequences determined. Here ...

Proposed minimal standards for describing new taxa of aerobic, endospore-forming bacteria
(Microbiology Society, 2009)
Minimal standards for describing new taxa within the aerobic endospore-forming bacteria are proposed, following Recommendation 30b of the Bacteriological Code (1990 Revision). These minimal standards are recommended as ...

Unravelling the adaptation responses to osmotic and temperature stress in Chromohalobacter salexigens, a bacterium with broad salinity tolerance
(BioMed Central, 2008)
Chromohalobacter salexigens, a Gammaproteobacterium belonging to the family Halomonadaceae, shows a broad salinity range for growth. Osmoprotection is achieved by the accumulation of compatible solutes either by transport ...

Rational design of a bacterial transcriptional cascade for amplifying gene expression capacity
(Oxford University Press, 2001)
Cascade regulatory circuits have been described that control numerous cell processes, and may provide models for the design of artificial circuits with novel properties. Here we describe the design of a transcriptional ...

Differential expression of the TFIIIA regulatory pathway in response to salt stress between Medicago truncatula genotypes
(American Society of Plant Biologists, 2007)
Soil salinity is one of the most significant abiotic stresses for crop plants, including legumes. These plants can establish root symbioses with nitrogen-fixing soil bacteria and are able to grow in nitrogen-poor soils. ...

Accidentes de trabajo derivados de la exposición a la bacteria Legionella pneumophila
(Ministerio de Trabajo e inmigración: Instituto Nacional de Seguridad e Higiene en el Trabajo, 2006)
La legionelosis es una enfermedad que puede afectar al ámbito laboral. El análisis de las sentencias que se realiza en este artículo pone de manifiesto este hecho. De ahí que sea necesario el estudio del agente biológico ...

Enhanced Symbiotic Performance by Rhizobium tropici Glycogen Synthase Mutants
(American Society for Microbiology, 2001)
We isolated a Tn5-induced Rhizobium tropici mutant that has enhanced capacity to oxidize N,N-dimethyl-p-phenylendiamine (DMPD) and therefore has enhanced respiration via cytochrome oxidase. The mutant had increased levels ...

Plant polycistronic precursors containing non-homologous microRNAs target transcripts encoding functionally related proteins
(BioMed Central, 2009)
Background MicroRNAs (miRNAs) are endogenous single-stranded small RNAs that regulate the expression of specific mRNAs involved in diverse biological processes. In plants, miRNAs are generally encoded as a single species ...
