dcterms:description
V práci byl studován vliv tří toxických kovů, hliníku, niklu a mědi na aktinový a tubulinový cytoskelet modelové zelené řasy Spirogyra decimina. Zjistili jsme, že měď (CuSO4) měla nevratně depolymerizující účinek na cytoskelet, zatímco hliník (AlCl3) a nikl (NiCl2) způsobovaly pouze mírné reverzibilní změny (změny orientace mikrotubulů, slabá depolymerizace mikrotubulů nebo aktinových filament). The effect of the toxic metal ions, aluminium (Al3+), nickel (Ni2+), and copper (Cu2+) of different concentrations, on both the actin and tubulin cytoskeleton of the green alga Spirogyra decimina was studied. The impact of copper on the morphology of both MTs and AFs was much more prominent than the other two metals. A rapid irreversible depolymerization of cytoskeletal structures occurred, whereas in the presence of aluminium or nickel, changes in the cytoskeleton were slight and reversible to some extent. Nickel changed the orientation of cortical MTs, which turned from a transverse to a skewed or longitudinal direction. Aluminium caused slight depolymerization of the cytoskeleton, which was able to revert spontaneously.
