Effect of CFCS produced by Pseudomonas kilonensis Ba35 and Pseudomonas chlororaphis Ba47, and Serratia liquefaciens Ou55, on swarming, swimming, twitching, and chemotaxis motility of A. tumefaciens Gh1, compared to the non-treated control (Ctrl). The diameter of swarming motility zone (a), and representative plate of swarming motility assay (b), the diameter of swimming motility zone (c), and representative plate of swimming motility assay (d), the diameter of the twitching motility zone (e), and representative microscopic examination of the peripheral edge of twitching motility (f), and the number of cells attracted toward root extract of grapevine cv. Rashe (g) were shown. Three replicates were used for each treatment. Error bars indicate the SE of the three replicates. Different letters indicate significant differences (P = 0.05)
