EXPRESSING THE MAIZE ANTHOCYANIN REGULATORY GENE Lc INCREASED FLAVONOID CONTENT IN THE SEED OF WHITE PERICARP RICE AND PURPLE PERICARP RICE

摘要

The colour of red, purple, brown and white occurs in pericarp of rice. Here, the maize anthocyanin regulatory gene Lc under control of the promoter of the rice glutelin gene Gtl was introduced in the white pericarp rice "Chao2-10" and purple pericarprice "Qingjiaozidao". The results demonstrated that some transgenic "Chao2-10" rice pericarps became brown, and the total flavonoid contents in the unpolished rice of the two transgenic rices increased significantly compared with their respective controls. Unpolished rice kernel thickness and weight in the two transgenic rices decreased slightly.
