Genetically Modified Multi-Nutrient Rice Offers Three Micronutrients Against MalnutritionAugust 16, 2017
A group of researchers from ETH Zürich led by Navreet Bhullar and her PhD student Simrat Pal Singh have succeeded in genetically modifying a new rice variety that not only has increased levels of the micronutrients iron and zinc in the grains, but also produces beta-carotene, a precursor of vitamin A.
The group's success was the engineering of a gene cassette containing four genes for the micronutrient improvement that could be inserted into the rice genome as a single genetic locus. This allows the iron, zinc, and beta-carotene levels to be simultaneously increased by genetic crosses in rice varieties from different countries, instead of crossing rice lines with the individual micronutrients to reach their improved content in rice grains.
The new multi-nutrient rice lines are still being tested in the greenhouse and analyzed for their micronutrient content. Bhullar hopes that the new rice lines will be tested in the field next year.
