Transgenic soybean hairy roots with silenced GmWRKY40 exhibit enhanced susceptibility to Phytophthora sojae. a Disease phenotypes of GmWRKY40-RNAi Williams 82 hairy roots and control at 36 h after inoculated with P6497. b The lesion length of P6497 infected hairy roots. Lesion length was taken 36 hpi. c Relative expression of GmWRKY40 was determined by qPCR at 12 and 24 hpi in GmWRKY40 silencing or EV hairy roots (d) P. sojae biomass was determined by qPCR at 12 and 24 hpi in GmWRKY40 silencing or EV hairy roots. The experiments all above were repeated three times along with at least three independent repetitions of the biological experiments. Error bars indicate the standard error. Asterisks indicate statistically significant differences (**P < 0.01)
