 Abstract 


Anthocyanin-rich purple rice is considered to be a particularly healthy natural food. To investigate anthocyanin biosynthesis in purple rice, two inbred lines (YDD1 and YDD2) were selected to undergo different light stress treatments. The accumulation of anthocyanin in purple rice leaves was mainly regulated by light intensity and wavelength. Compared to Nipponbare, the concentration of anthocyanin in purple rice was significantly induced under high light intensity (150 µmol m-2 s-1) and blue light (470nm light wavelength). High light intensity and 470 light wavelength also induced the transcription of several genes, including the anthocyanin biosynthesis genes OsCHS, OsCHI, OsF3H, OsDFR, and OsANS. Two regulatory gene products, OsB1 and OsB2, were significantly and differentially expressed between YDD1 and YDD2, indicating a complex regulated pathway in purple rice.
