Fig. 1. Analysis of sterols and sterol derivates in ugt80A2,B1 mutant relative to wild-type.<br />

Total sterol derivatives were quanti�ed and compared between wild-type and mutant<br />

plants in mg per gram dry weight-1 as A) FS + SE and B) SG + ASG. FS+SE was the sum of<br />

FS measured by GC-FID + sterols measured by GC-FID released from SE fraction after<br />

saponi�cation. Values are the mean of three replicates and experimental analysis was<br />

duplicated; error bars indicate standard error from the mean.
