FfMYB15 could bind and activate FfCEL6B promoter. a EMSA. The purified FfMYB15 recombinant protein was used as a negative control alone. The symbols – indicate protein or probe not added. + and +  + represent increasing amounts of unlabeled or mutant probes used for competition and testing of binding. b Structural diagram of the effector and the reporter c FfMYB15 activates the transcription of FfCEL6B. The ratio of Luc/Ren of empty plasmid plus promoter was used as the standard and set to 1. Each value represents the mean ± S.E.M. (n = 6). **refers to statistically significant differences at P < 0.01
