Regulators Classify Gene-Edited Rice Varieties with Disease Resistance as Equivalent to Conventional Varieties

The Healthy Crops team, with support from the Bill & Melinda Gates Foundation, have used gene editing tools to develop new varieties of disease-resistant rice that regulators in the United States and Colombia have determined are equivalent to what could be accomplished with conventional breeding.

Grain traits traced to ‘dark matter’ of rice genome

Domesticated rice has fatter seed grains with higher starch content than its wild rice relatives — the result of many generations of preferential seed sorting and sowing. But even though rice was the first crop to be fully sequenced, scientists have only documented a few of the genetic changes that made rice into a staple food for more than half the world’s population.
