Transgenic rice line producing high level of flavonoids in the endosperm

摘要

The present invention is to develop transgenic rice to generate high levels of flavonoids in the entire endosperm. Varieties of rice, Oryza sativa japonica cv. Hwa-Young is transformed with maize C1, and RS gene activating with most of the structural gene in the flavonoid biosynthetic pathway. C1 and RS transgene of the expression profile 13-kD rice specifically expressed in the entire endosperm roller Min gene the specific-promoter for use in the endosperm. 27 individually C1 / RS lines of transgenic T1 lines, most of the grains in a light brown-colored variations are transformed with only the vector of rice plants as well as distinctly darker than the wild-type grain. T2 and T3 homozygous transgenic lines bonding properties of the grain is colored darker than the T1 grain size is smaller. ; Endosperm, a flavonoid, a biosynthesis pathway, transgenic rice, grain, vector
