Quantification of endogenous BRs in wild-type and bia1-1D plants. A, BR levels measured in wild-type (WT; numbers to the left of the dash) and bia1-1D (numbers to the right of the dash) plants projected onto the proposed BR biosynthesis pathway of 24-methylenecholesterol. Numbers are in ng/g of fresh weight. B, Relative abundance of BRs in WT and bia1-1D plants. The level of each compound in the BR biosynthesis pathway in wild-type plants was arbitrarily set to 100.
