Answer:
Due to mutation.
Explanation:
Due to mutation, the rice plants are able to produce gluten like other grain crops such as wheat etc. In this mutation, change occurs in a DNA sequence of the rice plant by exposing the plant to ionized radiation. Due to this radiation, change occurs in the DNA of rice plant and the rice plant is able to produce gluten like wheat plant. So mutation is a very useful method for producing substances which a plant can't produce in its normal condition.
