Relative expression level of qRT-PCR. a: Relative expression of PeWRKY31 in different transgenic lines. b: Relative expression of NtWRKY31 in different transgenic lines. The means ± SD of three biological replicates are presented. Error bars represent the standard deviation of the mean. Different letters above the bars indicate a statistically significant at the P < 0.05 level according to LSD multiple range test
