Effects of VOCs produced by Serratia sp. Ba10, Enterobacter sp. Ou80, Pantoea sp. Sa14, Pseudomonas sp. Ou22, Pseudomonas sp. Ba35, and Pseudomonas sp. Sn48 on chemotaxis behavior of Agrobacterium tumefaciens Gh1 toward root extract of grapevine cultivars Rashe, and Bidane sefid, (a) colony diameter, and (b) number of cells migrated towards the attractant compared to the untreated control (Ctrl). Three replicates were used for each treatment. Error bars indicate SE of the three replicate. Different letters indicate significant differences (P = 0.05).
