Also: GMO crops, Bt crops, Golden Rice, CRISPR crops, transgenic plants
Crops changed by adding genes (transgenic) or editing their own genes (e.g. CRISPR). Examples include Bt insect-resistant crops, vitamin-A Golden Rice and CRISPR-edited wheat. All have public regulatory histories. Descriptive only.
