Transgenic rice seed as a nutriceutical delivery system.

Takaiwa, F.
Rice is consumed as a staple food by more than half the world's population. If rice were nutritionally fortified or biofunctionally enhanced by genetic modification, it could contribute to the promotion of human health without the need for processing and purification. Incorporation of health-promoting bioactive components or nutrients could thus result in public health benefits that significantly reduce health care costs. Rice seed has many advantages as a production platform of nutrients and biofunctional products over other cereals or vegetative crops in view of productivity and cost, and the fundamental tools required for genetic modification technology have been established for rice. The entire rice genome has been sequenced and is readily accessible, and transformation and expression systems are well developed for a number of agronomically important rice cultivars. The focus of this review is the present state of development of nutritionally improved rice, and transgenic rice seed as a production and delivery system for recombinant products.
