(C) PHR1 enhances the growth of Pto DC3000 under Pi-starvation conditions. Col-0, phr1 mutant and PHR1-Myc overexpression seedlings grown in either HP or LP media were root inoculated (by soaking) with a bacterial suspension (OD600 = 0.2) for 2 min, and the number of bacteria from individual roots 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.
