The improvement of Golden Rice and its implementation for the potential alleviation of vitamin A deficiency

摘要

Golden Rice is the name given to genetically modified rice which produces p-carotene (pro-vitamin A) in the grain. In the body, P-carotene is converted to vitamin A. We found that using an alternative phytoene synthase transgene resulted in an increase of P-carotene levels by up to 23 fold. Although the nutritional benefit will depend on the uptake and bioconversion of P-carotene, the new 'Golden Rice 2' has the potential to provide a child's RDA in just over two portions of rice. The activities underway for its implementation will be discussed.
