    Morphofunctional Evidence of Changes in Principal and Mitochondria-Rich Cells in the Epidermis of the Frog Rana kl. esculenta Living in a Polluted Habitat

    The epidermis of vertebrates is the body’s principal barrier against environment and its possible contaminants. The presence of keratins, as well as specific detoxifying molecules or enzyme activities, in the ...

    Little Egrets (Egretta Garzetta) and Trace-Metal Contamination in Wetlands of China

    The rapidly develo** Asian countries may face threatening environmental contamination, that however remains largely unassessed. We studied persistent trace elements in three wetlands, Poyang Lake, relatively...

    Egrets as Monitors of Trace-Metal Contamination in Wetlands of Pakistan

    Environments in Pakistan are subject to increasing pollution, but previous studies were very scanty. During 1999 and 2000, we assessed trace element contamination at three wetlands, Karachi Harbour (with presu...

    Isolation and molecular characterization of theSinorhizobium meliloti bet locus encoding glycine betaine biosynthesis

    To cope with osmotic stress,Sinorhizobium meliloti accumulates organic compatible solutes such as glutamate, trehalose, N-acetylglutaminylglutamine amide, and the most potent osmoprotectant glycine betaine. In or...

    Expression Analysis of the Bet Locus Encoding the Glycine Betaine Biosynthesis Pathway in Sinorhizobium meliloti

    Glycine betaine can be used both as an osmoprotective molecule and as carbon and nitrogen source for growth by S. meliloti. It is synthetized from choline by a two-step pathway catalyzed by the enzymes choline de...

    Molecular Characterization of a Binding Protein-Dependent-Transport System for Glycine Betaine in Sinorhizobium meliloti

    S. meliloti can use glycine betaine as an effective osmoprotectant at high osmolarity and a glycine betaine-binding protein has been identified in the periplasmic fraction (Le Rudulier et al., ...
