Golden rice is a variety of Oryza sativa rice produced through genetic engineering to biosynthesize beta-carotene, a precursor of vitamin A, in the edible parts of rice. The research was conducted with the goal of producing a fortified food to be grown and consumed in areas with a shortage of dietary vitamin A, which is estimated to kill 670,000 children under 5 each year.
Golden rice differs from its parental strain by the addition of two beta-carotene biosynthesis genes. The scientific details of the rice were first published in Science in 2000, the product of an eight-year project by Ingo Potrykus of the Swiss Federal Institute of Technology and Peter Beyer of the University of Freiburg. At the time of publication, golden rice was considered a significant breakthrough in biotechnology, as the researchers had engineered an entire biosynthetic pathway.
In 2005, a new variety called Golden Rice 2, which produces up to 23 times more beta-carotene than the original golden rice, was announced. Neither variety is currently available for human consumption. Although golden rice was developed as a humanitarian tool, it has met with significant opposition from environmental and anti-globalization activists.

Famous quotes containing the words golden and/or rice:
“I wandered lonely as a cloud
That floats on high o’er vales and hills,
When all at once I saw a crowd,
A host, of golden daffodils;”
—William Wordsworth (1770–1850)
“The arbitrary division of one’s life into weeks and days and hours seemed, on the whole, useless. There was but one day for the men, and that was pay day, and one for the women, and that was rent day. As for the children, every day was theirs, just as it should be in every corner of the world.”
—Alice Caldwell Rice (1870–1942)
