Conteúdo: 	Cadmium uptake and subcellular compartmentation in the ectomycorrhizalfungus Paxillus involutus were investigated using radiotracer fkux analyses. Concentration-dependent Cd2+-uptake kinetics were characterizedby a snooth, non-saturating curve that could be dissected into linear and saturable components. The linear-uptake kinetic component was interpreted as representing binding of Cd to apoplastic components, whereas the remaining saturable component was the result of carrier-mediatedtransport across the plasma membrane. Cell-wall-bound Cd was almost completely removed during desorption from cell-wall preparations. Cd2+desorption from intact mycelium was found to be a function of time involving three compartments corresponding in series to cell wall (50%), cytoplasm (30%) and vacuole (20%), when mycelia were exposed to a 0-05uMCd concentration.
