THE PECULIARITIES OF RARE-EARTH IONS EFFECT ON ROTATIONAL CHLOROPLAST MOVEMENT VELOCITY

The chloroplast movement velocity (CMV) in Elodea leaves in norm and under the effect of copper ions and rare earth ions (REI) praseodim and gadolinium was recorded by synchronic following method (SF). The differences In CMV dynamics are associated with unequal ion permeability velocity through plasmalemma, different sites of binding on actin - ATP - myosin motor complex, possibility of blocking of transmembrane ion transfer channels for REI.
