Genetics and Genomics Interventions for Promoting Millets as Functional Foods.

Several crops, including millets with immense nutritional and therapeutic values, were once a part of our regular diet. However, due to domestication and selection pressures, many of them have become marginally cultivated crops confined to a particular region, race, or locality. Millets are a perfect example of neglected species that have the potential to address both food and nutritional insecurities prevalent among the ever-growing global population. Starvation and malnutrition contribute to a large number of health-related issues, being the main reason behind the occurrence of most of the severe diseases worldwide. These constraints are repeatedly disturbing both the social and economic health of global society. Naturally, millets are rich in minerals, nutrients, and bioactive compounds, and these crops are less dependent on synthetic fertilizers, systemic irrigation, and pest/weed control. Given this, the review emphasizes the nutritional values, health benefits, processing techniques, and genomic advancements of millets. In addition, it proposes a roadmap for enhancing the utility and commercialization of millets.

Exploration of millet models for developing nutrient rich graminaceous crops.

Protein-energy malnutrition and micronutrient deficiencies contribute to high mortality among considerable proportion of the current 7.2 billion global populations, especially children. Although poverty and diets poor in nutrition are prime reasons for prevalence of malnutrition, nutritionally dense crops offer an inexpensive and sustainable solution to the problem of malnutrition. Remarkably, millets are nutritionally superior to major non-millet cereals. They especially are rich in dietary fibers, antioxidants, phytochemicals and polyphenols, which contribute broad-spectrum positive impacts to human health. However, millets have received lesser research attention universally, and considering this, the present review was planned to summarize the reports available on nutrition profile of millets and non-millet cereals to provide a comparative insight on importance of millets. It also emphasizes the need for research on deciphering nutritional traits present in millets and to develop strategies for introgressing these traits into other conventional staple crops using germplasm and 'omics' technologies. In some millet species, excellent 'omics' and germplasm panels have started to get available which can act as a starting point for understanding as well as of introgressing healthful traits across millets and non-millet cereals.
