Inhibition of A. flavus spore germination by extracts of embryogenic cultures (A) and leaves (B); inhibition of A. flavus fungal growth on peanut cotyledons from T4 progenies of CPO transgenic line 104-4-8 T0-5 T1-3 T2-3 (C). GG : non-transgenic Georgia Green. * and ** denote significant differences between the transgenic lines and GG at P<0.05 and P<0.01 levels, respectively. Error bars indicate standard deviation. Mean separation was performed by Tukey's method.
