The effect of REE on viability of suspension culture of Arabidopsis thaliana was also tested. Toxicity of Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu, at five different concentrations (in the range 0.05 - 5 mM) was tested by standard ecotoxicity test. The root length of white mustard was measured after 72-h incubation. The elongation inhibition, EC50 value and slope values were calculated. The exposure of suspension culture of Arabidopsis thaliana took 96 h under dark condition. The tolerance of suspension cultures to REE was assessed using the reduction of 2,3,5-triphenyltetrazo-lium chloride (TTC). The results showed that REE toxicity decreased in the order: Lu > Er > Yb > Sc > Tm > Y > Ce > Ho > La >Nd > Pr > Dy > Gd > Tb > Eu > Sm.
