Abstract
Plant growth promoting rhizobacteria (PGPR) serve as an alternative tool in sustainable agriculture.PGPR influence the heavy metal accumulation of crops in contaminated soils, either by decreasing or increasing the accumulation.This study focuses on the effect of plant growth-promoting rhizobacteria on the heavy metal uptake, plant growth and stress response of bean plants.The simultaneous treatment of Cd 2+ and Mitsuaria chitosanitabida T310 -2 /4 (PGPR strain) as well as Zn 2+ and bacteria resulted in the inhibition of root elongation in bean plants, but no differences were recorded in root biomass.A higher accumulation of the phytotoxic Cd 2+ in the root compared to the shoot was observed in bean plants due to the limited translocation (varying between 7.95-23%).In the case of Zn 2+ treatment the translocation from root to shoot was not limited.In the case of Cd 2+ treatment the Mitsuaria chitosanitabida T310 -2 /4 decreased the accumulation of Cd 2+ in bean plants.Differences in polyphenol oxidase (POD) and peroxidase activity (GPOX) were observed among metal stressed and control plants.Mitsuaria chitosanitabida T310 -2 /4 strain diminished the oxidative stress in the case of toxic metal (Cd 2+ ) treated bean plants most probably due to the inhibited metal uptake.
