Insights into the recent approaches for rice (Oryza sativa L.) biofortification

Abstract

Rice is the most essential source of calories for humans among the cereals and over half of the world's population is fed on rice. As part of a complete food systems approach, biofortification is an effective technique for nutrition enrichment which refers to the development of micronutrient-rich diet by utilising traditional breeding practises and sophisticated biotechnological tools. To enhance the profile of rice grain for biofortification-related properties, researchers must first understand the genetics of critical biofortification characteristics. Significant increases in micronutrients like iron and zinc, as well as many other important minerals and provitamins are acquired in rice grain using the biofortification strategies. Most indica and japonica rice types have been biofortified over the world, giving them the titles of high iron rice, low phytate rice, high zinc rice, and high carotenoid rice or golden rice. Some of the recent approaches towards rice biofortification, as well as their effects, have been explored in this article.
