2.5.1.116	physiological function	transgenic expression of the barley homogentisic acid geranylgeranyl transferase in Arabidopsis thaliana leaves results in accumulation of tocotrienols, which are absent from leaves of nontransformed plants, and a 10- to 15fold increase in total tocotrienols plus tocopherols. Overexpression of the barley enzyme in corn seeds results in an increase in tocotrienol and tocopherol content of as much as 6fold	Hordeum vulgare
