Relative swarming motility of Bacillus cereus AR156 (A) and Ralstonia solanacearum HN4 (B) on 0.5% Luria-Bertan (LB) or 0.7% Yeast-Glucose-Peptone-Agar (YGPA) plates amended with tomato root exudate induced by Bacillus cereus AR156 (REB), tomato root exudate induced by water (REW) or different components from tomato root exudates induced by B. cereus AR156 at final concentrations of 0.01, 0.1, 1, and 10 mM centrally inoculated with 5 μl of AR156/HN4 cells freshly grown (OD = 0.8) and incubated for 10 h and 5 days respectively at 28°C. The mean and standard error values of six biological replicates are reported for each treatment. Asterisks in (A,B) indicate statistical significance difference between data of treatments and data of tomato root exudate induced by sterile water (REW) within each experiment as determined by the Student’s t-test (∗P < 0.05, ∗∗P < 0.01). The experiment was carried out three times and one representative experiment is reported.
