Effects of selected halo-rhizobacteria and purified Exo1 on the germination, growth and nutrient uptake ability of salt-tolerant rice under salt and arsenic stresses. Average root and shoot lengths (A) and average fresh and dry weights of roots and shoots (B) of germinated rice seeds in plate-based germination assay. Average root and shoot lengths (C) and average dry weights of roots and shoots (D) of 15-day old germinated rice seedlings in pot-based growth assay. Amounts of phosphate (${\text{PO}}_4{}^{3-}$) (E) and nitrogen (N₂) (F) uptaken by the roots and shoots of 15-day old germinated rice seedlings in pot-based growth assay. Error bars represent mean ± standard deviation of triplicate values. * denotes statistical significance with respect to NaCl (control) whereas ** denotes statistical significance with respect to As (control).
