(G) Growth of Pto DC3000 in Col-0 and RALF23-OE lines under Pi-starvation conditions. Seedlings grown in either HP or LP media were root soaking inoculated with bacterial suspension (OD600 = 0.2) for 2 min, and the number of bacteria from individual roots was quantified at 0 dpi and 3 dpi. The data shown indicate the means ± SDs (n = 27, n refers to the number of roots per group); n.s., not significant; **, p < 0.01 (Student's t test). Data information: All experiments were repeated three times with similar results.
