  1. 1. Mechanisms behind pH changes by plant roots and shoots caused by elevated concentration of toxic elements

    Författare :Muhammad Tariq Javed; Maria Greger; Sylvia Lindberg; Marinus L. Otte; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Elodea canadensis; Eriophorum angustifolium; fluorescence microscopy; mechanisms; metals and metalloid; pH changes; protoplasts; phytofiltration; phytostabilization; root exudates; Plant Physiology; växtfysiologi;

    Sammanfattning : Toxic elements are present in polluted water from mines, industrial outlets, storm water etc. Wetland plants take up toxic elements and increase the pH of the medium. In this thesis was investigated how the shoots of submerged plants and roots of emergent plants affected the pH of the surrounding water in the presence of free toxic ions. LÄS MER

  5. 4. Efflux of Sucrose from Mesophyll Cells during Apoplastic Phloem Loading in Pea

    Författare :Chana Opaskornkul; Jim McDonald; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fysiologisk botanik; Physiological Botany;

    Sammanfattning : Efflux of sucrose from photosynthesizing mesophyll cells into the apoplastic space, during apoplastic phloem loading, was investigated using suspension of protoplasts and inside-out plasma membrane vesicles isolated from mature leaves of in Pisum sativum L. cv. Fenomen. LÄS MER

  7. 5. Production and characterization of intraspecific somatic hybrids of potato (Solanum tuberosum L.)

    Författare :Sylvia Waara; Uppsala universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : A culture protocol has been developed for mesophyll protoplasts isolated from various d¡haploid clones of potato. A large number of call¡ was obtained after serial dilution of the cultures w¡th a suitable amount and type of medium at different stages of cell colony development. LÄS MER
