[Effects of plant growth-promoting rhizobacteria Klebsiella michiganensis TS8 and Lelliottia jeotgali MR2 on the growth and cadmium uptake of Arabidopsis thaliana under cadmium stress].

(234% and 35%) at both low and high concentrations. In addition, at low concentration, both single strain and mixed strains significantly improved the transformation from reducible Cd to acid-extractable Cd in soil, promoted Cd intake, and thereby reduced the total Cd content in soil. Therefore, the rational application of plant growth-promoting bacteria may improve crop yield and remediate Cd contamination in soil.
