GMO Golden Rice is promoted as a potent tool to alleviate vitamin A deficiency. However, Indian researchers now report that the genes needed to produce it have unintended effects. When they introduced the engineered DNA, their high-yielding and agronomically superior Indian rice variety became pale and stunted, flowering was delayed and the roots grew abnormally. Yields were so reduced that it was unsuitable for cultivation (Bollinedi et al. 2017).
