Figure 4. H. seropedicae strains competition for attachment on maize roots.

H. seropedicae wild type (black bars) and epsB ⁻ (gray bars) strains were inoculated on maize separately (A) or co-inoculated in a 1∶1 proportion (B), with the total of bacteria inoculated per plantlet indicated in the x axis. Results are shown as average of Log₁₀ (number of recovered attached bacteria.g⁻¹ of fresh root) ± standard deviation, CFU = colony forming units.
