Salinity renders the plant susceptible to Salmonella. (a) Number of lateral roots upon treatment with varing amount of NaCl. (b) Salmonella colonization on arabidopsis roots treated with 50 mM and 100 mM NaCl. One way ANOVA followed by Bonferroni’s post test was used to analyse the data. Different letters shows significance at P < 0.05. (c) Correlation between salt stress and Salmonella colonization on arabidopsis root (at 95% CI). The values in parenthesis represent number of lateral root (Mean ± SD). (d) Number of lateral root of tomato plotted against varying salt stress. One way ANOVA followed by Bonferroni’s post test was used to analyse the data. P < 0.001 = ***; ns = not significant. (e) Tomato fruits infected with Salmonella upon mild salinity stress (25 mg NaCl/g soil; EC = 2.25dS/m). Each experiment was repeated 3 times with 3 replicate each. Mann-Whitney test was used to analyse the data. P < 0.05 = *
