Tolerance of T2–T4 transgenic lines to Phytophthora root and stem rot under greenhouse conditions. (A) Tolerance responsed 10 days after inoculation with P. sojae race 1. JN21, susceptible cultivar Jiunong 21; W82, wild-type Williams 82; 8096 to 8253, T3 transgenic lines. (B) Survival rate of three generations of transgenic lines inoculated with P. sojae race 1. All experiments were replicated thrice with 20 inoculated plants per replicate. The average survival rate of each transgenic line was calculated 7 days after inoculation. Error bars indicated standard errors and asterisks denoted significant differences between the transgenic line and the corresponding WT plants at P < 0.01
