    Evidence for the cytoplasmic localization of betaine in leaf cells of Suaeda maritima (1978)
    Springer
    Planta 140 (1978), S. 59-62

    Thema: Biologie
    Notizen: Abstract An attempt has been made to localize glycinebetaine in shoots of Suaeda maritima L. Dum. using a technique based on the formation of an iodoplatinate precipitate. Deposits were largely restricted to the cytoplasm of salt-grown plants and were analysed by transmission analytical electron microscopy. The results are considered to support the hypothesis that glycinebetaine acts as a cytoplasmic osmoticum to balance high vacuolar salt levels in certain halophytes.

    Quantitative ion localization within Suaeda maritima leaf mesophyll cells (1981)
    Springer
    Planta 151 (1981), S. 555-560 
    Details
    ISSN: 1432-2048
    Schlagwort(e): Halophyte ; Ion accumulation ; Suaeda
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie
    Notizen: Abstract Grown under saline conditions, Suaeda maritima accumulates Na+ and Cl- into its leaves, where individual mesophyll cells behave differently in their compartmentation of these ions. Measurements of ion concentrations within selected subcellular compartments show that freeze-substitution with dry sectioning is a valuable preparative technique for analytical electron microscopy of highly vacuolate plant material. Using this approach, absolute estimates were made of Na+, K+ and Cl- concentrations in the cytoplasm, cell walls, chloroplasts and vacuoles of leaf mesophyll cells.
