Fig. 9 The expression levels of defense-related genes A-E: the relative expression levels of POD, PPO, PAL, PR10, JAR1; control meant cotton first treated with LB medium, and then inoculated with Vd080. EBV02 meant cotton first treated with EBV02 culture solution and then inoculated with Vd080. * indicates significant difference between the treatment and the control (P<0.05).
