Vitamin -A deficiency causes night blindness among children. Vitamin - A deficiency often occurs where rice is the staple food since rice grain does not contain Beta carotene. Three transgenic providing phytoene synthase, phytoene desaturase, zeta-carotene desaturase and lycopene cyclase activities were transferred into rice by Agrobacterium mediated transformation. The resulting transgenic rice popularly called golden rice contains good quantities of Beta-carotene.
