Fig. 2. The percentage of various isoflavonoids of total isoflavone fractions extracted from either upper or lower root parts of ‘PI 520733’, ‘PI 567374’, and ‘Spencer’, either inoculated or not inoculated with Fusarium solani f. sp. glycines 7 d after planting. Bars represent standard errors of the means. Daidzin, 7-O-glucosyl daidzein; MGD, 6''-O-malonyl-7-O-glucosyl daidzein; MGGn, 6''-O-malonyl-7-O-glucoside genistein; MGGl, 6''-O-malonyl-7-O-glucosyl glycitein.
