%X To investigate the effect of bacteria Burkholderia sp. D54 on Cs uptake by P. americana Linn and A. crenentus L., a pot experiment with different concentrations of Cs was conducted. It was found that inoculation of Burkholderia sp. D54 on P. americana Linn. and A. crenentus L. enhanced total biomass of P. americana and A. crenentus by 19.8%~33.4% and 22.9%~76.6%, respectively. Shoot Cs concentration of P. americana and A. crenentus increased by 4.9%~22.4% and 8.1%~19.4%, while root Cs concentration increased by 6.8%~15.7% and 1.1%~10.8%, respectively. We also concluded that inoculated Burkholderia sp. D54, increased potassium uptake by two types of plants, enhanced net assimilation rate, stomatal conduction, transpiration and water use efficiency of photosynthesis of the two types of plants, increased the activity of antioxidant enzymes CAT, POD and SOD under Cs stress, and reduced plants MDA content in leaves.
