Effects of volatiles produced by Bacillus strain D13 on cell motility in Xanthomonas oryzae pv. oryzae (Xoo). Xoo cultures were spotted onto the compartments of divided plates containing 0.7% (w/v) or 0.3% (w/v) nutrient agar (NA) medium; strain D13 was cultured in a separate compartment containing Luria broth (LB) medium. Control plates contained Xoo on one half and no Bacillus‐inoculated LB medium on the other half. (A) Swarming and swimming haloes of Xoo exposed to strain D13 volatiles for 3 days. (B) Real‐time polymerase chain reaction (PCR) analysis of motA, motC and rpfC expression in Xoo cells after co‐cultivation with strain D13 for 36 h. Values were normalized to the levels of 16S rRNA, an internal reference gene. Three replicates were used for each treatment, and the experiment was repeated three times. Vertical bars represent standard errors. Asterisks above the bars indicate a significant difference (P < 0.05).
