The present invention is in the field of plant genetics and biochemistry.
More specifically, the present invention relates to genes and
polypeptides associated with the tocopherol biosynthesis pathway, namely
those encoding homogentisate prenyl transferase activity, and uses
thereof. In particular, the sequence of the HPT2 gene from Arabidopsis
thaliana is disclosed for expression in any plant species to increase the
levels of tocopherol.
