Accumulation of K. radicincitans DNA in inoculated radish plants with amidated pectin dried beads. Effect of pre-conditioning of K. radicincitans in culture media by osmoadaptation at 1% NaCl, at 4% NaCl, and 4% NaCl + hydroxyectoine [1 mM], on relative gene expression in plant tissue. Different letters above bars indicate significant differences of treatments according to Tukey post hoc test at p < 0.05, (means ± SD, n = 4).
