  • The quantities of tocopherols, carotenoids, plastoquinone, and phylloquinone in the rosette leaves (per gram fresh weight [FW]) and purified thylakoids (per milligram of chlorophyll [Chl]) were determined from the indicated plant lines. Data are the means of at least three independent determinations ± sd, and bold numbers indicate significant difference (Student’s t test, P < 0.05) when comparing the quantity of various isoprenoids to those found in wild-type samples.
