(E) RALF23/34 promoted the growth of Pto DC3000 in phr1 mutants. Col-0 and phr1 mutant seedlings grown in LP media were root inoculated (by soaking) with a bacterial suspension (OD600 = 0.2) for 2 min, and the number of bacteria from individual root was quantified at 5 dpi. The data shown indicate the means ± SDs (n = 18, n refers to the number of roots per group). The different lowercase letters indicate statistical significance (one-way ANOVA). Data information: All experiments were repeated three times with similar results.
