Genomics-assisted breeding approaches for protein biofortification in rice grains

Rice serves as a fundamental dietary staple for billions worldwide, but often lacks sufficient nutritional value, particularly in terms of protein and essential amino acids. This abstract offers an overview of the composition, distribution, and recent advancements in protein and amino acid enhancement in rice, highlighting strategies to boost its nutritional profile. Through traditional breeding and modern biotechnological methods, researchers have developed rice varieties with higher levels of key amino acids such as lysine, methionine, and cysteine, along with increased overall protein content. These biofortified rice varieties show promise in combating protein malnutrition and associated health issues, especially in vulnerable communities. However, the successful implementation of biofortification programs requires careful consideration of safety, regulations, environmental sustainability, and socio-economic factors. This emphasizes the need for collaboration among researchers, policymakers, and agricultural stakeholders to ensure widespread adoption and equitable distribution of biofortified rice varieties. Continued research and investment in protein and amino acid enhancement offer significant potential in addressing global malnutrition and improving public health outcomes.
