Levels of MEP-derived and MVA-derived isoprenoid products in plants with reduced G11 activity. A, Seedlings of the indicated mutants and the parental Columbia wild-type (WT) grown for 1 week under short-day conditions. These seedlings were used for the metabolite analyses shown in the corresponding graphs. B, Levels of the indicated carotenoids in albino mutants relative to those in wild-type seedlings. C, Levels of major sterols in wild-type and G11-defective g11-5 seedlings. D, Levels of the ubiquinone UB-9 in seedlings, flowers, and young siliques of wild-type and g11 -5 plants. The graphs represent mean and se of at least n = 3 independent samples. Italic numbers above the bars indicate P values (Student’s t test) relative to g11-2 (B) or wild-type (C and D) samples.
