Question

Which of the following is true for Golden rice?

Difficult

A

It has yellow grains, because of a gene introduced from a primitive variety of rice.
B

It is vitamin A enriched, with a gene from daffodil.
C

It is pest resistant, with a gene from Bacillus thuringiensis.
D

It is drought tolerant, developed using Agrobacterium vector.

Solution

This rice is rich in beta-carotene or vitamin A. In this case two genes are introduced from daffodils (Narcissus- plant) and the third one from the soil becteria Erwinia uredovora. Genes are inserted in edible parts of rice to produce beta-carotene which further produces pro-vitamin A. This rice has 23 times more beta-carotene than the original rice.
