Genetic Mutation in Orange Cauliflowers, Identified
Scientists have identified the genetic mutation leading to orange cauliflowers.
The genetic mutation recently isolated by Cornell plant geneticist Li Li and colleagues -- and described in the December issue of The Plant Cell -- allows the vegetable to hold more beta-carotene, which causes the orange color and is a precursor to the essential nutrient vitamin A. While cauliflower and many staple crops have the ability to synthesize beta-carotene, they are limited partially because they lack a "metabolic sink," or a place to store the compound.

The finding may lead to more nutritious staple crops, including maize, potato, rice, sorghum and wheat.
