Give any two examples of biofortified transgenic crops.

1.	Give any two examples of biofortified transgenic crops.
Answer» Examples of biofortified transgenic crops are as follows: 1. Golden rice and Golden mustard These are transgenics rich in vitamin A. 2. Arabidopsis genes are transferred to soybean, oil palm, rapeseed and sunflower for improvement in oil content and oil quality. 3. Ferritin, an iron storage protein, isolated from soybean and Phaseolus is transferred to rice to increase its iron content. 4. Plants deficient in amino acids like methionine, lysine and tryptophan have been engineered to improve protein content.
