The effects of growth regulator of the new generation-melamine salt of bis(oxymethyl)phosphine acid (melafen)--on culture growth, pigment and protein content, and the induction of protective chloroplastic chaperone HSP70B in Chlamydomonas reinhardtii CW15 cells were studied. Melafen exhibited 10-30% growth inhibition at 10(-9)-10(-2)% concentration. At 10(-9)-10(-4)% of melafen electrophoretic concentration, the pattern of cellular proteins was similar to the control. The alterations in protein content of algae cells were detected only at 10(-2)% concentration. The content of chlorophyll and carotenoids in melafen-treated cells was 17-40% lower than in the control. Melafen at 10(-9)-109-2)% concentration inhibited HSP70B induction by 39-43% compared to untreated cells. The potential mechanism of melafen effect might involve its influence on nuclear gene expression. |
