Dynamic Changes in Vitamin E Biosynthesis during Germination in Brown Rice (Oryza sativa L.).

ABSTRACT: The present study investigated the dynamic changes in vitamin E and gene expression within its biosynthetic pathway during three germination periods of four brown rice cultivars with different seed coat colors. The results reveal that the vitamin E content increased during the germination process of all brown rice cultivars. Moreover, the content of α-tocopherol, α-tocotrienol, and β-tocopherol significantly increased at the later stage of germination. The expression levels of DXS1 and γ-TMT genes in all cultivars were significantly increased, whilst the HGGT gene expression levels of G6 and XY cultivars increased significantly at the later stage of brown rice germination. In addition, the expression levels of MPBQ/MT2 in G1 and G6 cultivars, and TC expre
