Genetically modified rice are rice strains that have been genetically modified (also called genetic engineering). Rice plants have been modified to increase micronutrients such as vitamin A , accelerate photosynthesis , tolerate herbicides, resist pests, increase grain size, generate nutrients, flavors or produce human proteins.
Golden rice is a variety of rice (Oryza sativa) produced through genetic engineering to biosynthesize beta-carotene, a precursor of vitamin A, in the edible parts of the rice. [ 1 ] [ 2 ] It is intended to produce a fortified food to be grown and consumed in areas with a shortage of dietary vitamin A .
Golden rice is genetically modified for an increased nutrient level, which has a different color and vitamin A content. Golden rice is the most well known GM crop that is aimed at increasing nutrient value. It has been engineered with three genes that biosynthesise beta-carotene, a precursor of vitamin A, in the edible parts of rice. [130]
A genetically modified organism (GMO) is any organism whose genetic material has been altered using genetic engineering techniques.The exact definition of a genetically modified organism and what constitutes genetic engineering varies, with the most common being an organism altered in a way that "does not occur naturally by mating and/or natural recombination".

Agricultural biotechnology, also known as agritech, is an area of agricultural science involving the use of scientific tools and techniques, including genetic engineering, molecular markers, molecular diagnostics, vaccines, and tissue culture, to modify living organisms: plants, animals, and microorganisms.

By cross-breeding together IR8 with 13 parent varieties from six nations, Dr. Khush developed IR36, a semi-dwarf variety that proved highly resistant to a number of the major insect pests and diseases that raised farmers' rice yields and drove down prices of the staple food for Asian families. [1]
In 2006, the U.S. Department of Agriculture announced that Bayer CropScience's LibertyLink genetically modified rice had contaminated the U.S. rice supply. Shortly after the public learned of the contamination, the E.U. banned imports of U.S. long-grain rice and the futures price plunged.
This genetically modified form of cultivated rice has, however, appeared on the rice market. [3] [4] [5] One way sometimes used for combating weedy rice is to plant a red rice one year and on that land a green rice next year, and so alternating, and in each crop to pull up any rice plants that are the wrong color for that year.
