Bacterial inoculation promotes plant growth and alleviates LP stress. Arabidopsis seeds were germinated on 1/2-strength MS media for 3 days and then transplanted to either HP or LP media for another 5 days. The seedlings were then transferred to vermiculite and inoculated with Pto DC3000 or B. subtilis. (B), The seedlings were harvested, and the shoot fresh weight was measured 4 weeks after inoculation. The data shown indicate the means ± SDs (n = 30, n refers to the number of seedlings per group), Central bands: median, boxes: interquartile range, whiskers: max./min; n.s., not significant; *, p < 0.05, **, p < 0.01 (Student's t test). Data information: All experiments were repeated three times with similar results.
