Abstract

The brown macroalgae Laminaria digitata (Huds.) Lamour., L. hyperborea (Gunn.) Foslie, and L. saccharina (L.) Lamour. (Laminariales, Phaeophyceae) have been investigated for carbon assimilation and assimilate biosynthesis in different tissues (meristoderm, cortex, medulla) of stipes and blades. Carboxylation via ribulose-1,5-bisphosphate carboxylase (EC 4.1.1.39) and phosphoenolpyruvate carboxykinase (EC 4.1.32) follows a transversal gradient from the outer to the inner tissues with maximum activity of enzymatic CO2 fixation in the meristoderm. Such transversal profiles are also recorded for photosynthetic and dark carbon assimilation as well as for kinetics of assimilate 14C-labelling in isolated tissues. Differential chemical constitution of the blade and stipe tissues examined and results from assimilate biosynthesis are discussed with regard to a transversal translocation of photosynthates from meristodermal to cortical and medullar cells.
