Chemotaxis of strain EGB towards cucumber root exudates on TPM plates. a Diagram of the chemotactic response of EGB to the chemicals. b Feasibility test of the chemotaxis assay with citrate acid. c Chemotaxis of strain EGB towards cucumber root exudate. RE, root exudates of cucumber; black arrow, sites where asymmetric swarming occurred; white arrow, sites where the chemicals were dropped; red dotted line, edge of the swarming colonies of strain EGB. The experiment was repeated four times, with three replicates each time
