Fig. 7. — Vitamin E biosynthesis in barley and Arabidopsis. HPT (homogentisate phytyltransferase) and HGGT (homogentisate geranylgeranyl transferase) are the committed-step enzymes for the biosynthesis of tocopherols and tocotrienols, respectively. The question mark indicates an HPT homologue or other vitamin E biosynthesis pathway-related genes that may participate in tocopherol production in barley and other monocots. HGA, homogentisate; PDP, phytyl diphosphate; GGDP, geranylgeranyl diphosphate; T, tocopherol; T3, tocotrienol; hpt, HPT mutant; vte2, HPT mutant in Arabidopsis; hggt, HGGT mutant. Red circles represent tocopherols; blue triangles represent tocotrienols.
