    Major transcription factor families at the nexus of regulating abiotic stress response in millets: a comprehensive review
    (Springer Nature Publishing AG, 2024) Prusty, Ankita; Panchal, Anurag; Singh, Roshan Kumar; Prasad, Manoj
    Millets stand out as a sustainable crop with the potential to address the issues of food insecurity and malnutrition. These small-seeded, drought-resistant cereals have adapted to survive a broad spectrum of abiotic stresses. Researchers are keen on unravelling the regulatory mechanisms that empower millets to withstand environmental adversities. The aim is to leverage these identified genetic determinants from millets for enhancing the stress tolerance of major cereal crops through genetic engineering or breeding. This review sheds light on transcription factors (TFs) that govern diverse abiotic stress responses and play role in conferring tolerance to various abiotic stresses in millets. Specifically, the molecular functions and expression patterns of investigated TFs from various families, including bHLH, bZIP, DREB, HSF, MYB, NAC, NF-Y and WRKY, are comprehensively discussed. It also explores the potential of TFs in developing stress-tolerant crops, presenting a comprehensive discussion on diverse strategies for their integration.

    The promise of millets in the twenty-first century: emphasis on breeding, nutrition, food security and sustainability
    (Springer Nature Publishing AG, 2023) Bandyopadhyay, Tirthankar; Singh, Roshan Kumar; Ramesh, Palakurthi; Maurya, Jyoti; Prasad, Manoj
    Global population is expected to cross 11 billion by the turn of the century, which has put immense pressure on the existing agricultural systems worldwide. This is complicated by gradually decreasing productivity and acreage as a result of climate change in addition to ever-increasing input costs of resource hungry staple crops like rice, wheat, and maize. Unfortunately, the most affected by these events are those who have the least resources at their disposal to mitigate the issue, especially in countries of Asia and Sub-Saharan Africa. It is therefore pertinent to explore and adopt alternative and/or complementary crops that are easier to cultivate, climate change tolerant, less resource hungry, nutritionally richer for human consumption, and agriculturally sustainable. Millets are perfect cereal crops which meet all of these requirements and can realistically provide much-needed solutions to current global food and nutritional security challenges. In this review, we provide a bird’s eye view of the relevance of millets in global agro-ecosystems in the context of their nutritional and agronomic attributes. Furthermore, we share perspectives on the major areas of crop improvement programs worldwide and discuss major challenges confronting the same. Finally, we discourse on the scope of millets for wider acceptability and highlight major points at the interface of genetic intervention–crop management post-harvest practices worth considering to potentially facilitate robust millet-based nutritional and food security.

    Genetics and genomics interventions for promoting millets as functional foods
    (Bentham Science, 2021) Dhaka, Annvi; Singh, Roshan Kumar; Muthamilarasan, Mehanathan; Prasad, Manoj
    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.
