In English, "millet (s)" refers to a group of cereal grains. Millet is a staple grain in several impoverished countries, as well as a part of many more prosperous countries' traditional diets, and it is growing increasingly popular across the world. It is a valuable source of dietary energy. Millet seeds are shown to have various health-promoting properties as well as of their high calorie level. Millets have been utilized for both human food and fodder for around 10,000 years. It thrives in dry, hot regions and produces small, seeded grasses. While millets are a valuable source of protein, calories and minerals, there hasn't been much research on the potential of biotechnology to enhance millets. Researchers and scientists have conducted studies with millets; here, we assess their nutritional value and write about how biotechnology can improve millet crops.

Millets, comprising a diverse group of small‐seeded grains, have emerged as vital crops with immense nutritional, environmental, and economic significance. The comprehension of complex traits in millets, influenced by multifaceted genetic determinants, presents a compelling challenge and opportunity in agricultural research. This review delves into the transformative roles of phenomics and genomics in deciphering these intricate genetic architectures. On the phenomics front, high‐throughput platforms generate rich datasets on plant morphology, physiology, and performance in diverse environments. This data, coupled with field trials and controlled conditions, helps to interpret how the environment interacts with genetics. Genomics provides the underlying blueprint for these complex traits. Genome sequencing and genotyping technologies have illuminated the millet genome landscape, revealing diverse gene pools and evolutionary relationships. Additionally, different omics approaches unveil the intricate information of gene expression, protein function, and metabolite accumulation driving phenotypic expression. This multi‐omics approach is crucial for identifying candidate genes and unfolding the intricate pathways governing complex traits. The review highlights the synergy between phenomics and genomics. Genomically informed phenotyping targets specific traits, reducing the breeding size and cost. Conversely, phenomics identifies promising germplasm for genomic analysis, prioritizing variants with superior performance. This dynamic interplay accelerates breeding programs and facilitates the development of climate‐smart, nutrient‐rich millet varieties and hybrids. In conclusion, this review emphasizes the crucial roles of phenomics and genomics in unlocking the genetic enigma of millets.

“…As the human body cannot synthesize Se, dietary supplementation is the safest way to meet Se requirements ( Rider et al., 2010 ). Utilizing biofortification techniques to enhance the nutritional value of staple crops is a cost-effective and feasible approach to mitigate micronutrient deficiencies ( Ingle et al., 2023 ). Foxtail millet, rich in carbohydrates, proteins, fatty acids, vitamins, and minerals, is considered one of the most important nutritional cereals ( Xiang et al., 2019 ), and its biofortification significantly contributes to nutritional security ( Kaur et al., 2019 ).…”

IntroductionSelenium-enriched foxtail millet (Setaria italica) represents a functional cereal with significant health benefits for humans. This study endeavors to examine the impact of foliar application of sodium selenite (Na2SeO4) on foxtail millet, specifically focusing on selenium (Se) accumulation and transportation within various plant tissues.MethodsTo unravel the molecular mechanisms governing selenium accumulation and transportation in foxtail millet, we conducted a comprehensive analysis of selenium content and transcriptome responses in foxtail millet spikelets across different days (3, 5, 7, and 12) under Na2SeO4 treatment (200 μmol/L).ResultsFoxtail millet subjected to selenium fertilizer exhibited significantly elevated selenium levels in each tissue compared to the untreated control. Selenate was observed to be transported and accumulated sequentially in the leaf, stem, and spikes. Transcriptome analysis unveiled a substantial upregulation in the transcription levels of genes associated with selenium metabolism and transport, including sulfate, phosphate, and nitrate transporters, ABC transporters, antioxidants, phytohormone signaling, and transcription factors. These genes demonstrated intricate interactions, both synergistic and antagonistic, forming a complex network that regulated selenate transport mechanisms. Gene co-expression network analysis highlighted three transcription factors in the tan module and three transporters in the turquoise module that significantly correlated with selenium accumulation and transportation. Expression of sulfate transporters (SiSULTR1.2b and SiSULTR3.1a), phosphate transporter (PHT1.3), nitrate transporter 1 (NRT1.1B), glutathione S-transferase genes (GSTs), and ABC transporter (ABCC13) increased with SeO42- accumulation. Transcription factors MYB, WRKY, and bHLH were also identified as players in selenium accumulation.ConclusionThis study provides preliminary insights into the mechanisms of selenium accumulation and transportation in foxtail millet. The findings hold theoretical significance for the cultivation of selenium-enriched foxtail millet.
