title: Starch-related carbon fluxes in roots and leaves of Arabidopsis thaliana.
abstract: Both photoautotrophic and heterotrophic tissues from plants are capable of synthesizing and degrading starch. To analyse starch metabolism in the two types of tissue from the same plant, several starch-related mutants from Arabidopsis thaliana were grown hydroponically together with the respective wild type control. Starch contents, patterns of starch-related enzymes, and the monomer patterns of the cytosolic starch-related heteroglycans were determined. Based on the phenotypical data obtained, three comparisons were made: First, data from leaves and roots of the mutants were compared with the respective wild type controls. Secondly, data from leaves and roots from the same plant were compared. Third, we included data obtained from soil-grown plants and compared them with those from hydroponically grown plants. Thus, phenotypical features reflecting altered gene expression can be distinguished from those that are due to the specific growth conditions. Implications on the carbon fluxes in photoautotrophic and heterotrophic cells are discussed.
