To the editor:

In the October issue, a letter from Alexander Stein and his collaborators (Nat. Biotechnol. 24, 1200–1201, 2006) discussed the potential impact and cost effectiveness of Golden Rice. What we know about Golden Rice today is that plant breeders have successfully genetically modified rice to express β-carotene; what we also know is that, after a first approach (Golden Rice 1) they obtained rice plants that supply only 15–20% of the recommended dietary allowance for vitamin A; further genetic tinkering has resulted in rice plants (Golden Rice 2) that accumulate levels of β-carotene 20-fold higher.
