Figure 11. Reversion of fps2-1 phenotypes by expressing FPS2 under the control of the FPS1 promoter.

Sitosterol (A) and HMGR activity (B) levels in seeds from Arabidopsis wild-type, fps2-1 and the indicated lines of the fps2-1 mutant harbouring FPS1mutdisp::FPS2 and FPS1p::FPS2 chimeric genes. Values are expressed relative to the wild-type values. Data represent the mean values and SE of three independent experiments. (C) Reversion of mevastatin hypersensitivity. Representative seedlings of the same lines were grown for 12 days under long-day conditions (16 h light/8 h dark) on MS plates supplemented with 1 µM mevastatin.
