Rice engineered with genes for β-carotene biosynthesis (Ye et al., 2000) resulted from an intellectual property donation from several multinational companies, including Syngenta, Monsanto, Bayer, and Mogen. These genes are now used in developing tropical elite indica rice using the nonantibiotic selectable marker pmi (phosphomannose isomerase) gene (Figure 7; Datta et al., 2003), which might be able to reduce vitamin A deficiency. Moreover, iron has been enhanced in indica rice by introducing the ferritin gene driven by the
