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 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]
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 .
Genetically modified plants can also be developed using gene knockdown or gene knockout to alter the genetic makeup of a plant without incorporating genes from other plants. In 2014, Chinese researcher Gao Caixia filed patents on the creation of a strain of wheat that is resistant to powdery mildew .
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".

HarvestPlus, a major NGO in the development of biofortified crops, primarily use conventional breeding techniques, and have not yet spent more than 15% of their research budget on genetically modified crops when conventional methods fail to meet nutritional requirements. [5] [6] Golden rice is an example of a GM crop developed for its ...
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.

In 2014, 181.5 million hectares of genetically modified crops were planted in 28 countries. Half of all GM crops planted were genetically modified soybeans, either for herbicide tolerance or insect resistance. Eleven countries grew modified soybean, with the USA, Brazil and Argentina accounting for 90% of the total hectarage.
